Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

Hi.

Got a 2016 golf about 18 months ago.

A week ago there was a slight loss of power and white smoke coming out the exhaust.

Next morning the engine started shaking.

Diagnostics showed error code p00af and p2536 turbo charger sensor error.

Then the coil and engine light came on and a warning that oil pressure is low.

Had it towed to two different places that said that engine was out of oil for probably days or weeks and when they topped it up, the white smoke from exhaust was too much.

Initially they just said that's it's a non runner sc*** and no hope at all.

Then they told me it might need a turbo replacement, and if that doesn't work, then engine replacement and they'll be happy to do it for me if I provide the parts etc etc.

Car had absolutely no issues or warnings before all this.

Now it's just parked and I'm struggling to find any solutions or workshops that can provide any sort of solutions

Don't want to keep getting it towed back and forth to different places and being told different variations of the same stuff.

Car has only 60k miles on it and has been perfect upto this point so I'm not sure I want to sc*** it just yet.

Can anyone provide any sort of advice or suggestions about how to proceed?

Thanks

It sounds like the turbo to me. What engine do you have?

Personally, I'd get it towed to a decent VW specialist and brace myself.

If it’s run out of oil , the turbo is usually one of the first components to self destruct. Doesn’t sound promising.
Volkswagen Golf - 2016 golf engine issues - gordonbennet

If you've run it out of oil the engine's basically knackered, if you are a good DIYer you might be able to strip and rebuild not a serious proposition paying someone else skilled enough do do this.

So the question is, was it out of oil? if so you need another engine and ancilliaries from an accident damaged write off.

Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

I'm not savvy so ill need to find a specialist.

There were no warning lights but I did check oil visa the dipstick and it was fine.

The garage told me it had no oil and probably didn't have any for days. Probably weeks.

I didn't notice any change in performance so didn't think of checking the oil.

Any estimates about the time and costs if it is engine replacement or just turbo?

Thanks

Thanks for the reply. It's a diesel 1.6

Volkswagen Golf - 2016 golf engine issues - Adampr

New engine would be a write off. Turbo, I don't know, but probably tipping over £1k at a VW dealer or specialist.

The 1.6 TDI has a bit of a reputation for oil-based problems. As yours hasn't been driven much over the years, it may have been gradually clogging. Even if a new turbo fixes the current issue, there are several things that could have started it off and cascades to where you are now.

As before, get it taken to a specialist, but they may well say it's not worth fixing.

Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

Ah ok fair enough. Thanks for taking the time.

I'll wait till I find a decent specialist and take it from there.

Incase if it's a write off, what would be the options about what to do with it?

Volkswagen Golf - 2016 golf engine issues - Adampr

When I said 'write off' I meant that it would probably cost more.to fix than it would to go and buy an identical car. I may well be wrong though, given the price of used cars these days - it would appear that your car is probably worth about £10k....

There is a garage near me that seems to exclusively sell Japanese imports and cars that have broken their timing chains. That means very little, other than that there is obviously a gap between the cost to repair and the retail value.

Have it looked at by a specialist who knows the characteristics of the engine and take it from there.

Because c.r.a.p. are the last 4 letters.

Though oddly, doesnt the Mary Whitehouse Module allows you to call the 2017 Engine of The Year (awarded by an International panel of journalists, who should know c r a p when they see it, given that they are heavily involved in its production)

"The Purec*** engine"

Ok, apparently not. Could have sworn I'd see someone do that, but maybe they were using the spaced character circumvention?

Apparently Mary doesnt move in mysterious ways after all.

Sorry to hear about your engine OP. They need oil.

AFAIK there is no real way to assess the extent of engine damage caused by lubrication..er...failure, other than by stripping it and looking at the bearing surfaces, though if it cant be rotated by hand its had it, and with experience the effort involved in rotation by hand could probably give a pretty good clue. A look at the cylinder walls with a borescope, and maybe a compression test (though you need special gear for diesels so likely not DIY-realistic) might also be informative.

Otherwise its educated guess territory, but you can probably get away with stuff on a lower compression petrol engine that will be terminally destructive on a diesel.

Sounds like your engine is still running, but the turbo is bust, and the remaining lifespan of the bearings is unknown. It'll very likely be shortened, but its not possible to say by how much. An oil analysis, which your average garage will probably know nowt about, could give you a clue. You send a sample off to a lab and the lead, copper and particulate content allows them to assess bearing wear. About 40 quid IIRC.

Once upon a time it might have been possible(though non-trivial) to delete your turbo (if that were all that was bust) but that probably isnt practical on a recent highly integrated unit with no comparable NA model.available;

oilanalysislab.com/contact-oil-analysis-laboratori.../

I THINK this is the lab I posted about before, distinguished by allegedly providing info on large wear particles, which are normally missed by a standard spectrographic analysis.

Large wear particle info is useful as an early warning of engine failure.

IIRC a one-off sample wasn't very expensive, but pricing has apparently become more opaque,(if you dont have an account, which I dont) and the website more "hypey" than I remember.

Couldn't hurt to enquire though.

Can I clarify when the fault happened did you still have oil still showing on the dipstick as the two statements above are conflicting? On Vag cars you normally get an oil LEVEL (orange) warning if the oil level is low well before damage is caused.

If you had no oil then the engine/turbo will be probably cream crackered.

However this could have been a cataphoric turbo failure which can cause a drop in oil PRESSURE (red) as pumped oil is squirting past turbo bearing / seals and down the exhaust causing the drop in pressure and smoke. I think in either scenario the turbo has gone but there might be a CHANCE the engine is ok if you stopped very quickly although this won't have done the cat & DPF much good either.

One option is to try posting on eBay declaring the issue - you may be surprised at the outcome especially as the car is probably registered as euro 6 ULEZ compliant,

Hi folks.

Thanks for the replies even though most of it is alien to me.

The car had absolutely no warning lights whatsoever.

No drop in performance or anything of the sort.

It had oil. Got a mate around with obd who checked just to make sure it had oil.

It was only the garage people who said it's been out of oil although currently, it's the garage people that were a bit shady by the looks of things.

It's finally with a reliable VW place so fingers crossed.

Of course I have no experience of newish cars, and dont much want any,

BUT does one really use an obd reader to check the oil on a 2016 VW Golf?

Please say it isn't so.

Haha. No. Meant that I got the mate around to check fault codes and while he was here, got him to check the oil the usual manual way.

Two seperate prcoesses.

Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

So the garage said turbo is gone and needs replacement.

470 for a new turbo and 1000 for labour.

They are saying they are confident but cannot officially gurantee this would fix everything and there is a possibility of further issues/expenses.

However, they cannot do anything or check anything else before turbo replacement.

Can someone advise whether the costs qouted are reasonable, and how to do pro's/con's to go ahead with it or not.

Many thanks.

Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

to add, they said dpf is blocked and theyll need to clean that as well so costs include that as well.

Volkswagen Golf - 2016 golf engine issues - Adampr

The price for the turbo seems about right. On the labour costs, I wouldn't know how long it takes to replace one, or what their rate is, but it seems at the high end of the reasonable range. There is always someone who'll do it cheaper so, in your position, I would probably go on reputation rather than just the bottom line.

The DPF will be full of oil from the turbo s***ting itself so, yes, it will need to be cleaned.

£470 for a turbo (re-man?) seems reasonable but £1000 for labour seems a bit much.

I would hope this includes clearing crud from turbo oil feed and drain pipes and filters, unless this is done the replacement turbo may not last long.

Volkswagen Golf - 2016 golf engine issues - elekie&a/c doctor
Turbo failure is usually the result of some other problem , usually oil related . The fact you had the low oil pressure warning displayed indicates this engine has more issues than you may think. It’s worrying that you could spend all this money and not get to the root cause of the problems.

More specifically, he might be putting a new turbo on a wrecked engine.

OP, before taking this risk, I'd say you should do/get done everything possible to check out your engine. This probably means finding a good diagnostician, a good trick if you can do it.

As well as the conventional compression test, endoscopy, oil analysis, turning over by hand, and perhaps other stuff I havn't thought of there is a thing called a Relative Compression Test, (look it up) which measures and records current draw on the starter as it turns over the engine.

This has the advantages that

(a) You dont need special high pressure diesel gear (but you do need an expensive scope)

(b) Used with the cylinders decompressed (injectors/glow plugs out?) it might, with experience, give clues as to the state of your bearings.

You'd need to find someone to do it and interpret the results though.

Volkswagen Golf - 2016 golf engine issues - Mallakxxxx

Afternoon all.

Thanks for all the advice and suggestions. Much appreciated.

From the information gathering so far, it is highly likely that replacing the turbo might be useless if irreparable damage is done already.

However it's been frustratingly hard to find any place/person that would provide a definite diagnosis. Since I've had to pay to tow it back and forth three times already, I've told the guy to go ahead with turbo replacement.

He's highly recommended and has explained as well that it's not risk free.

Hoping for the best, planning for the worst.

Will update when its done.

Thanks all.

Volkswagen Golf - 2016 golf engine issues - edlithgow

Dont think a definite diagnosis is possible short of an engine strip, only indications.

(Another possible indication that I forgot would be measuring oil pressure.)

One of the possible indications doesn't require towing anywhere, just posting off an oil sample.

Ultimately though, whatever clues you collect, it comes down to whether you feel lucky or not. I hope you are.

In future (Assuming there is one, which seems reasonable) perhaps worth trying to find out what the highest viscosity permitted (not just whats recommended) for that engine would be (assuming they allow you any leeway at all) since a higher viscosity is likely to give mildly compromised bearings an extended lease of life.

So the guy sent me this pic of blocked oil filter and said he's gonna sort this out and finish the replacement.

Also said that the engine is still shaking so might be injector issues next.

From the previous diagnostics, I remember someone mentioned something about cylinder 3 but not sure what.

Any ideas what could possibly be the next issue?

Going tomorrow morning to see what's what.

Volkswagen Golf - 2016 golf engine issues - edlithgow

Didn't think of that, though I should have. Perhaps I didn't because I've only ever had cars that would require you to cut the filter open to examine its contents, but maybe this one has a removable filter element. A relatively straightforward post-incident check.

TBH it sounds rather bad, though of course I havn't seen it.

One might consider getting the filter debris analysed (or just looked at by someone experienced) to try and asses where it came from.

Could be, most obviously, from turbo bearing breakup, or t could be that there is a failure elsewhere that has lead to the turbo bearing breakup. Either way, it suggests you have had circulating junk in your lubrication system, which wont all have been stopped by the oil filter and has likely done systemic damage.

I'd probably get an oil analysis done before finally calling it, but its not sounding such a good bet now.

Cylinder 3 comment is too vague to be interpretable.

No obvious (to me) connection between injectors and your lubrication system, so either you've got an independent fault, or the vibration reflects knackered bearings, (perhaps describable as "rod knock", though a mechanic should recognise that), or bore wear
