Now that my A3 1.9TDI MY2000 (distributor type fuel injection) is nearing 250K, I'm thinking about what to get next. From what I've read, the following is the situation on reliability with the various VAG 1.9/2.0TDI diesels (please correct me where I'm wrong!):

1.9TDI PD 105bhp - Bosch injectors - this engine is the best of the lot, bombproof and the only issues were cracked injector looms.

2.0TDI PD 140bhp - Bosch injectors - this engine suffered from cracked cylinder heads which was worse on 2003/04 engines, was improved on 05 engines, and generally solved on 06 engines. It also suffered with oil pump faliure, due to issuesd with the pump chain (?).

2.0TDI PD 140bhp - Siemens injectors - very troublesome engine with a high rate of injector faliures and also cracked injectors looms.

2.0TDI PD 170bhp - Siemens injectors - very troublesome engine with a high rate of injector faliures, cracked injectors looms, and DPF issues.

2.0TDI CR 140 + 170bhp - Siemens injectors - generally better due to redesigned injectors, but still suffers from injector faliures

VW - VW Diesels - which one? - 659FBE

If only things were as simple as the (correct as far as it goes) summary of VAG diesels above.

The 1.9 is definitely the pick of the PD bunch but you have missed out several versions. The best 1.9 PD of all is the 130 PS AWX/AVF (designations for N-S installation) but there are of course E-W derivatives of the same engine with differing codes.

The 130 PS PD will give the economy of the 105 PS version if you wish - or very useful performance in the real world of low speed torque.

There is also a 150 PS 1.9 which I do not recommend + a few odballs badged by SEAT.

The 2.0 PD is a real can of worms which I cannot recommend. Cylinder head problems have been evident across the range but there are two stone-dead killers. One is the oil pump drive on the balancer shaft engines (not all are). The hex drive shaft mills out the pathetic slots in the bore of the slave balancer shaft and oil pump drive is lost. The other is the Siemens injector saga.

Early DPF installations for the 2.0 PD are a potential money pit and will negate any diesel savings.

The jury is still out on the CR engines which run very nicely although lacking the "shove" of the higher powered PDs. I am less than convinced of the long term durability of a fuel pump lubricated in fuel (the PD pumps are oil lubricated) which develops pressures approaching 2 kBar.

I'll have another look when my AWX PD is worn out - but I think the complexity of the later DPF management systems will make these latest engines a liability to own.

If you want a newer car I'd go for the 104hp 1.9 PD diesel with a remap. Previous versions of this engine have been widely remapped and seem to be able to produce considerably more power with few issues.

Older cars - why not consider a Passat 1.9 TDI 130 (2000-2005 model), the Skoda Fabia vRS Mk. 1, also with the 130hp TDI engine, Skoda Octavia Mk1 if you need a larger car. Other cars available with the same engine such as Mk4 Golf, Seat Leon Mk 1, VW Polo GT (rare). These older cars benefit from not having a DPF with the associated risk of clogging if used for short journeys and eventually requiring replacement.

Other recent diesels without DPFs include the Honda Civic 2.2 CDTI and the Kia Cee'd CRDI (pre-2009).

I currently have a Leon FR TDI 1.9 with 150hp but the Polo GT I test drove seemed to pick up better, despite having the 130hp engine. I've also heard of camshaft wear issues with the 150hp motor on the SEAT Cupra forums.

It's a shame the later VAG diesels are so problematic - I deliberately opted for an older car to avoid the problems and also DPF issues...

VW - VW Diesels - which one? - cws

Thanks for the input above. I'd forgotten about the 130bhp 1.9TDI engines! The ideal next car would be the Passat 130bhp.

Was it just cam shaft wear issues with the 1.9TDI 150bhp?

I just can't believe how, after producing the brilliant 1.9TDI, VW messed up so much with the 2.0TDI....... That engine promised so much and should have been an improvement on the 1.9TDI. I guess we blame the bean counters AGAIN.

VW - VW Diesels - which one? - cws

By the way 659FBE - do you run/work at a garage, specialising in VW diesels?!!

VW - VW Diesels - which one? - 659FBE

No garage, just a history of working for a well respected (now gone) UK diesel fuel systems manufacturer followed by a stint running an engine test lab.

I too am amazed that VAG took their eyes off the ball in their diesel engine development programme, but I can guess what happened. The PD engines - brainchild of Bosch - gave VAG a clear lead and sold them a lot of cars worldwide. Unfortunately its component parts are very expensive.

Looming ahead is Euro IV> which usually mandates the use of a DPF in engines with a high specific output. This is the kiss of death for the PD which is unable to provide pressurised fuel when the engine exhaust valves are open in order to burn off the soot in the DPF. A CR engine can do this.

So, the writing was on the wall for the PD years ago, but VAG did two really stupid things in my estimation. Putting all of their best engineering effort into the CR engines, the modifications to the 1.9 to enable it to become a 4 valve 2.0 were probably done by the apprentice. I have found some design features of the 2.0 PD which in my judgement are "not quite right". The second thing they did to the PD was to form a joint venture with Siemens to make their own unit injectors in order to minimise the amount of third party profit they were paying. Bosch is a premium supplier (and knows it). VAG were paranoid about costs.

The Siemens injectors are about as wrong as it's possible to get in my design experience and I would not wish to own one. Observe the twin lever movement magnification system for the servo valve and consider the probable effects of (conductive) oil ingress into the piezo stack. Diesel engine oil is very sooty.

So, a bit of a sad story really. The CR engines might be alright, but the DPF and its control have in my view now wrecked the job.

For sensible money, a Euro III PD 1.9 is the best of the bunch - the 130 PS unit being the nicest to use with an outstanding light-foot fuel consumption. I have one.

I have no friends whatever within VAG...

Interesting information 659FBE.

Is it also true that some 130hp 1.9s contain piezo injectors, or were these restricted to the later 2.0 engines and the current 104hp 1.9?

I have to say that I'm not really impressed with the 150hp 1.9 in my Seat Leon - it feels sluggish picking up from low revs and does not really seem to respond unless driven with a lead foot and revved above 2500rpm. The usual issues (MAF, Intercooler pipe work, EGR) have been checked out and found to be OK.

MPG has also only been averaging 49 to date and quite a bit of that's been on motorways at steady speeds of 70-80mph without much acceleration.

Although the Ford diesels get a hard time for reliability issues, my old Focus 1.8TDCi pulled better from below 2000rpm and, after remapping, went harder when revved as well. This despite the old 8v all-iron Ford diesel being a pretty ancient design and not gaining much more than 20hp when remapped...

The jury is still out on the CR engines which run very nicely although lacking the "shove" of the higher powered PDs. I am less than convinced of the long term durability of a fuel pump lubricated in fuel (the PD pumps are oil lubricated) which develops pressures approaching 2 kBar.

I went from a 2.0 TDI PD 140 to the CR TDI 143, as you say there is less 'percieved' shove but this is just because the engine is much more flexible - amazingly so.

2.0 TDI's with engine code BRE are trouble-free generally, ie no oil pump or injector issues or any DPF.

The PD pumps can barely be called pumps, but are just cam-driven pistons, but I would think that CR rotary pump technology is mature now after the nightmares of the earlier systems on Fords etc. I occasionally put a bottle of 2-stroke oil in mine to be on the safe side, I guess 29,000 psi is quite a lot of fuel pressure !

VW - VW Diesels - which one? - dieselnut

I occasionally put a bottle of 2-stroke oil in mine to be on the safe side

I have a Passat with the same engine that has done 163k & have thought about adding 2 smoke oil for a bit of extra lubrication. I know it is 'low ash' but i'm worried it will help to block the DPF as the ash won't burn & just build up in the DPF.

VW - VW Diesels - which one? - Rattyvee

I've just hit 260000 miles in an 02 Passat estate

It's an AWX 1.9 TDi PD130

It's needed precisely NOTHING but oil, filters, belts

I drive very gently & avoid stopping or bunching up in traffic

I can get 60mpg if I take it easy

goes as fast as I need when called for

I'm looking for a newer car , probably an Octavia with the same type engine if possible !

VW - VW Diesels - which one? - 659FBE

Well done - best engine with good maintenance. I hope mine is as good - so far, no problems.

For a replacement, I would go for a 1.9 PD with Bosch injectors in the body/badge of your choice. This will limit you to about MY '05 (10th digit in VIN). Some surprisingly late Octavias were fitted with rotary pump engines, so you will have to find a very late Mk1 to get a PD 130 engine, which is the one to have. You should recognise a PD engine by now...

The cam cover should have a paper label giving the engine code (usually, but not always, 3 letters, eg. AWX). Alternatively the engine code is on the build sticker in the spare wheel well or on the inside front cover of the service book. Google the code for a quick way to get the important engine details.

I hope you find a good one. I've met all kinds of diesel engines in my time, and the AWX is the engine of my choice.

Personally I think the VEP (distributor pump) 4 cylinder TDI engine such as the 1Z, AHU, AFN, AHF, ASV and others is the best of the lot, absolutely bullet proof and go on forever.

VW - VW Diesels - which one? - geordie33
Very interesting discussion as I know little about engines.I have a 56 plate golf tdi sport.It has done 40k with a mixture of short runs and usually a couple of 50 mile runs per week.It has been no bother and I can get 60mpg no problem but reading about VAG diesels on this forum I was thinking of getting rid before problems start.Perhaps I will keep it after all.
VW - VW Diesels - which one? - Crasher

All of the basic engines on the Golf diesel are fine, the 150PS unit in the Golf 4 had issues with cam follower failure, some early 115PS versions failed in a big way with their con rod small ends and all the TDI's suffer from turbo issues, especially the Golf 5 140PS version BUT having said that the main block/head and extremely strong.

VW - VW Diesels - which one? - 659FBE

I would generally agree with you, but as usual from VAG, the route to a reliable engine is a complicated one.

The basic engine is very strong and long lasting given correct basic maintenance but the later PD engines suffered from "development" (cost cutting?) of the basic design which for me, makes the product less useful. The change from Bosch solenoid actuated to Siemens piezo actuated injectors for the later PDs is probably the best example, and there are some others.

I rest my case - one of the last 1.9 PDs with Bosch solenoid injectors and no DPF is the engine to have if low running cost is important to its owner.

Crasher, did you verify my observation that the cambelt tensioner nut tightening data is in fact moulded onto the upper belt cover on the 8V PD engines? I've looked at the recommended torque for an M8 nut in this position on engines made by others and the VAG figure is the tightest by a very long way. PSA recommend 20 Nm. Draw your own conclusions...

659.

VW - VW Diesels - which one? - Crasher

The reason for the change of injector design was that the 4 valve per cylinder layout did not allow room for the type used on the 8 valve, Siemens really screwed up with the Piezo injector manufacturing, a good basic design compromised by cost cutting as you say.

The real killer on all engines is extended drain oil change intervals, this was a marketing ploy that backfired, it is simply not possible to make the oil protect for 20K miles without some loss of protection. Nearly all my customers are on Platinum oil and 1 year/9300 mile intervals (except the 150PD which we recommend at 5K) and PD lifter failure is a thing of the past. Some customers do 20K or more a year and they insist on keeping these intervals, I don't argue as I will probably be making out the bill for a new engine in a couple of years. The lasted DLC treated lifters are also proving to be extremely good.

We have done a lot of 8v PD cam belts in the past few weeks and I still have not seen one with the tensioner torque spec on it.

Hi

I always read these detailed articles with great interest. Just a couple of questions out of interest / curiosity if I may (forgive the somewhat random nature of some of the questions, but I want to capitalise on the opportunity while there are a few very knowledgeable people fresh in discussion):

1. With regards to the VW CR 2L TDi, would there not be enough examples driving around by now to get a very good idea of whether this is a reliable engine or not? It’s used in so many applications and it’s been around for a few years now (I think).

2. In terms of the CR injectors being reliant on the fuel for its lubrication (I think 659FBE has raised concern about this somewhere), surely we must know by now how long these injectors will last as many other manufacturers (Fiat, BMW, Mercedes etc) have used CR system now for the better part of the last 10 years or so.

3. I have a 1.9 TDi Seat Altea XL with code BXE. Think it’s a much underrated car and it’s still running like clockwork after 5 years and 106k. I do maintain it by the book and then some though. Should I worry about this engine? I just ask because if I listen to what you guys always say it sounds like this one doesn’t fall into that vintage bracket you always talk about.

4. And now slightly off the diesel track following on from another thread – VW 1.4 Tsi. I drove a Passat 122ps DSG version in Germany about 3 or so years ago on holiday for 2000 km. Pulling very quietly and smoothly like an Ox from idle speed with 4 adults in a Passat – I thought it was the best thing since sliced bread. We achieved circa 42 mpg on that trip, which I thought was phenomenal at the time. Now I read that the engine has problems like time chains breaking etc. And on the twin charger there’s all sorts of horror stories. Can I assume that by now VW would be aware of these issues and that they would have sorted all these issues? So if I buy a 2011 or 2012 model second hand in 4 years time it would be fine from a design point of view. Rock solid like my other old car the Fabia 1.9 SDi, which I don’t think you’ll be able to nuke to death if you try. Or is that wishful thinking?

Would love your comments. Thanks

VAG have just won the Golden Carrrot award this year its awarded for the biggest disaster of the year in motoring inGermany.Its for the chain in the 1.4tsi.

VW - VW Diesels - which one? - 659FBE

Lots of points to think about here - the situation is very complex and the financial penalties for buying the "wrong" engine from VAG can be dire in view of most customer experiences with design problems out of warranty. I'll throw a few general points into the hat:

The great advantage of the PD as an operating system for a diesel engine is that the cam/roller follower system which any diesel fuel pump has to have, is oil rather than fuel lubricated. Injection pressures on all diesels are now so high (in order to achieve smoke and efficiency levels) that these components are highly stressed. In a common rail engine, the fuel pump is fuel lubricated - making the lubricity of the fuel a critical factor. They don't like petrol...

PD cams and followers last for ever - even if you use the wrong engine oil, it's the valve cams and followers which suffer damage.

The common thread here is engine development, and it's my deduction that VAG have run out of experienced engine designers - maybe those who detailed the original 1.9 PD have retired. The PD engine was, in my view "wrecked" by the switch to Siemens piezo injectors which will not tolerate sooty (conductive) engine oil and there have been other, equally fundamental changes from the 1.9 which do not meet my criteria for reliable operation. Chain drives are the best example.

The first 2.0 PDs for N-S installation (Audi) had twin Lanchester shafts chain driven from the crank. A recipie for failure due to torsional oscillation - and they all did.

The VAG "chain" engineer was evidently not pensioned off as other chain camshaf drives have appeared (see above post) which, quite evidently to me, have been designed with no regard for the dynamic forces under which they operate. Internal combustion engines are not electric motors.

I'll stop there - but suffice it to say that other than the simple oil pump drive on the 1.9PD (which lasts for ever - no torsionals), I have yet to see any chain drive from VAG which I would spend any of my own money on. Pity - bring the experienced engineers backout of retirement.

The current V6 VAG diesel engine is the worst example of a chain drive I have yet seen - complete disaster in my view. Google "VW SSP 325" (select quick view) and look about half way through for a drawing...

Thanks for all the comments. It's a shame, my current run around (Fabia 1.9 SDi) will still go for a long time I'm convinced, but it is already 10 years old and I fear the body will rust away around the oily bits which seem to be strong. The family car (Seat 1.9 BXE) is also still good, but I will have to replace them at some point in the next number of years. Sounds like it's not going to be with a VAG 1.6 / 2.0 CR TDi or the 1.4 Tsi. Mercedes engines I don't trust and BMW may or may not be good, but both are too expensive for the likes of me. Honda probably have a tough new 1.6 diesel, but they sadly stopped with the FR-V, suppose I can still go for the new civic as a replacement for the Fabia. Toyota Verso diesel is probably the other safe option. There's perhaps also the Nissan Qasqai + or the Ford C / S Max. Though I wonder whether these above mentioned cars are really that much more reliable than VAG's new CR diesel - are they? From what I see the Prius is very reliable and you now get a 7 seater, maybe that's the future then - electrical motor + Atkinson engine what can go wrong.....

Oh, almost forgot, the 1.4tsi won that award this year, was that for engines manufactured a number of years ago and are now showing their weak points or was that for engines manufactured in 2012 - or are they all teh same unchanged?

Thanks again

VW - VW Diesels - which one? - 659FBE

To answer the question above, I just might take a chance on a VAG CR diesel - but only after comprehensive Internet (and soul) searching for potential problems. This would satisfy my geneal liking for diesel engines both in terms of their inherent thermal efficiency and their ability to do my job which is towing and motorway cruising. For both of these applications, a high torque and highly (top) geared prime mover is a definite asset.

If my searches suggested the likely probability of DPF or timing drive or HP fuel pump failure, I would go for a petrol engine. This might well be Japanese, as they make these engines well. I'd find Japanese fittings, furniture, displays and ergonomics difficult to live with though. Their cars don't say "executive" on the boot lid any more, but the idiom is still there.

What year / month did piezo injectors replace solenoid injectors in the 1.9 engine?

Would I be correct in assuming that it took place at different times for different models? And if so, when did it happen for VW Golfs?

VW - VW Diesels - which one? - Crasher

As far as I know the 8v still uses solenoid injectors. The BKD is the most numerous 2L 16v unit and these suffered turbo, dual mass and cylinder head problems but generally are a very reliable unit.

Hi guys

Sorry to retrieve this old thread but I have a question that is related.

I am looking at buying a '57 Altea 1.9 diesel 105bhp. Having looked at the Vin i'm pretty sure the engine was a bxe but I am only going on memory.

Is this the VAG engine that has Bosch injectors?

Is there anything else I should be aware of if i purchase the car?

Thanks for all the info above, all good to know

VW - VW Diesels - which one? - cws

As far as I know, all of the 1.9TDI engines had Bosch injectors (some correct me if I'm wrong!), so you should be safe. I'm sure, however, that I've read about some issues on either the BLE or BXE engines breaking con rods (have a search on here/google it) - seemed to be specific to SEATs (not sure if BLE/BXE engines were SEAT only?) and SEAT dealers were trying to blame owners not keeping the oil topped up.....

Anyway, as the OP of this thread, I'll add that my time with VW diesels has now come an end. The 2.0TDI was just one of many reasons why it was time for me to ditch VAG, so went for a Mercedes C-Class 220 diesel > proven engine, timing chain as opposed to a belt and an autobox so no failing dmf's.

VW - VW Diesels - which one? - balleballe

I'm pretty sure that all PD injectors are Bosch

Edited by balleballe on 16/04/2013 at 11:26

VW - VW Diesels - which one? - 659FBE

They're not.

The 2.0PD when fitted with a 16V head (not all were) had Siemens piezo actuated injectors, some of which became the subject of a recall. This was due to sudden and unpredictable engine stoppage, probably caused by conductive oil ingress.

To the best of my knowledge, all PD engines with 8V heads (which also means all of the 1.9s) were fitted with Bosch electromagnetically actuated injectors. These are reliable.

VW - VW Diesels - which one? - Lewis77

Just googled the BXE engine/con rods issue you mentioned and there definitely appears to be a common problem here given the age and mileage of the vehicles it is happening to. I was on the verge of making an offer until I read your message, looks like I owe you (and others) one!

The question is what the heck do I look to buy now?!

VW - VW Diesels - which one? - cws

No problem Lewis77 - that's what the forum is for :-)

The 1.9TDI PD engine is a good lump, but seeing as you're looking at an Altea, I assume you also want space? I'd seriously consider a Skoda Octavia Estate - a mate has got one and it is brilliant. Well put together, and does everything well that it says on the tin. Stay away from the Golf Mk5 - bag of ****! Even though it is available with the 1.9TDI, my own personal experience was awful build quality, rust issues on the front wheel arches and an interior that looks tatty fast.

Pesonally I'd look at a Hyundai or a Kia. I continue to be impressed by the cars they produce and you've got a good warranty with them - they just seem to get better and better.

VW - VW Diesels - which one? - Lewis77

Cheers CWS the last car I bought was a lemon and i'm determined to avoid doing the same! Yes you're right I do want something with space, the Altea is by no means something I must have I just want something solid and reliable. I have looked at the Octavia and given it has the 1.9 PD 105 in it it has to be considered. It's daft that when we are talking about the likes of VW that they can have such common and expensive problems even if looked after right.

Funny you should say that about the Kia and Hyundai I asked Honest John and he suggested the same. Might have to adjust my thinking, he says that the 1.6 diesels didn't have DPF until 2010 either so it looks like it could be the way forward. They look to have good running costs as well. I'll get there in the end!

Thanks again

Ideally I am looking for an 03 A 4 Avant with an AWX engine 1.9 TDi to replace the A4 saloon I have with the same engine, which I am so impressed with.
Can you tell me which year to go for which will guarantee this brilliant engine and where do I look on the car to check I have the right engine.
Also is it safe to go for an auto version?
VW - VW Diesels - which one? - 659FBE

A 1.9PD A4 of that year will probably have the AVF engine - which is fine. It's very similar to the AWX but has the fuelling set for a slightly higher peak torque - on paper. When actually comparing them, there's much more difference between individual engine samples. My AWX out-performs many AVFs that I have driven - these engines vary quite a bit. A good one of either type will go like a steam train.

The way to tell them apart is to look at the auxiliary drive. The AWX has a separate drive belt for the aircon compressor which is mounted on the right hand side of the engine (looking towards the front). The AVF has one drive belt for the lot and the compressor is on the left.

The engine type designations are printed on the cambelt cover, on the build sticker in the spare wheel well, and on the front inside cover of the service book. The engine output in kW is also given - divide by 0.746 to get BHP (or 0.735 to get PS).

Both of these engines are useful and reliable - assuming correct maintenance (absolutely vital, as they are now old).

Beware any auto transmission - the torque of the PD wrecks them and their general reliability does not meet my standards. A failing auto usually begins to hesitate to engage reverse as the clutch drum breaks up. Expense quickly follows.

The 5 speed manual gearbox is better in all respects than the 6 speed and if you get one of the later ones (eg. GGB) the top gear ratio is very nearly as tall as the 6 speed unit (a difference of 120 engine rpm at 70 mph - not worth bothering about). The 6 speed units can suffer pinion bearing failure due to incorrect bearing preload and also have a linkage design which can make them sloppy when they age.

One advantage of the 6 speed transmission is that it is fitted with a larger clutch - not a deal breaker unless you are heavy on clutches or tow. As transmissions cost more than clutches, the 5 speed unit is generally a better choice. If test driving a 6, check for a road-speed dependent whine on and off load.

Good hunting. By far your biggest problem will be finding a car which has had good maintenance and annual oil changes of the correct type throughout its life. A main dealer service record is no guarantee of this - a good independent, in my experience, will have done a better job.

Thank you - that was a most interesting read. We have a Passat with the AWX 1.9 TDi PD130 engine and it has been both reliable and economical.

However I cannot say the same for the electronics and I am therefore looking around for a replacement. My inclination would be for an Skoda Octavia but I am now very skeptical about the later engines !

Your comments on the experienced (and now probably retired) engine designers were pertinent. It is hard to imagine that after designing and proving a good design some bright spark says "lets change all of this - I am sure it will be better"

I suppose the continual pressure to make it cheaper over rides everything else ?

And of course the 'make it cleaner and leaner' imperative.

Hi Steveieb, I know it's been 7 months since, but did you find a A4 PD130?

I have wasted no time at all in doing jobs on it as reccomended by 659 and craig pd/130,

1: front upper suspension pinch bolts

2:track rod end pinch bolts

3:Plenum chamber checked, rubber drains were removed, carpets dry.

4: Pollen filter upper foam seal siliconed.

I hope you found what you were looking for.

I feel able to contributhere having owned the lions share of the VaG engines mentioned. Had an A4 with the 1.9 AWX engine, it was sublime, took any amount of thrashing and always did late 40's mpg - bit smokey thoughh.

Had a Passat 2003 with the 105BHP engine this was trouble free but a bit puny - also I believe the engine internals of this engine are not as meaty as in the AWX engine.

Cam wear on all PD engines - lots of stories about this on the internet but this is almost always caused either by failure to service or the use of the wrong oil - ie not 507.6 or 507.7.

I have had an A4 with the 2.0 CR engine 65K miles with no problems at all (other than a failed DPF pressure sensor a 10 min fix).

Currently have a 2.0 CR Passat with 48K - not a peep of trouble and mid 50's MPG.

The CR engines are no longer critical for CAM wear as they dont dirive the unit injectors.

Agree that 2.0 PD engines around 2003-2005 had a catastrophic oil pump drive design fault but I luckily missed these.
