I'm looking to spend £6000 to £8000 on an A4 diesel (2000 or 2001 year model). I found a website called audidiesel (you can find them by searching google), they seem to be doing good business. I was wondering if you guys have any experience with this company. They specialise in high mileage audis.
How do A4 diesels hold up against high mileage (110,000 miles)? Will I be looking at massive repair bills some time in the future? I would like to put at least another 150,000 miles on it.
I think there have been a few back roomers who have called the A4 diesel a good car ruined by the engine. I don't know about high mileage but the low kilometreage one I have been using is dire - slow, noisy and not very economical (9 to 10 l per 100 km).
Are they reliable at high miles? No idea, it'll be going as soon as the company agrees to get me a replacement.
I have a high mileage (140k) 2.5 TDI 1999 A4. Runs brilliant. No squeeks rattles or similar from in the cabin and the engine purrs very nicely.
10K service intervals, although minor service is only £60 from audi dealer.
Quattro gives the car great stability especially in wet and the power from the 150bhp engine is fantastic. Sub 10 seconds for the 60 dash and quicker than most things on the road when you are moving.
Economy from this engine is around 38-42 mixed mpg, the 110 model you will get closer to 50.
The car feels like a quality product. Everything electrical works,
Only problem for me is the lack of space in the back - I could do with a bit more so I am looking to change for an A6 -ideally with the same engine.
My experiences with a 1998 A4 1.9 110bhp TDI are unfair because most of the problems I had between 70 and 100k miles were design/manufacturing faults since rectified.
So I list them in 2 categories:
1.Faults since hopefully designed/manufactured out
Catalyst: faulty baffles (tinkling sound from exhaust on idle. Can result in complete blockage. Manufacturing defects since remedied.
Front lower wishbone bushes. Failed after 80k miles. Since then I believe design has changed. Horrible squeak from front suspension on bounces.
2.Inherent Faults or Potential one. (may be redesigned/sorted. I dunno)
Aircon condenser failed. BIG bills to fix: dash strip donw. £800 ish
Timing belt tensioner. At 100k IT MUST have been changed at least once.. or twice (plus belt). Mine ground itself to death slowly : noise + rust around tensioner. If it goes HUGE bills. New engine.
See HJ on worn fuel injectors.. If they do wear engine will wear out by 150k.
And WEAR AND TEAR
Front disks: will or should have been replaced at least once.
Rears may be rusty. Mine all done at 70k - fron and rears.
I would certainly buy another Audi but not a 1.9 TDi. My two UK-based petrol cars have been marvellous and have cost buttons in repairs.
The 1.9TDi quattro in Spain is another matter altogether, I find it noisy and simple unacceptable in what is supposed to be a prestige car. I have found the economy to be very disappointing and the build quality is simply not what it was even 3 years ago.
The 2.5 TDi is another matter altogether, still noisier than a petrol but at least it goes well.
My Seat Toledo TDiSE 1.9 110 bhp, which I bought new towards the end of 1999, has now done almost 185, 000 miles and is the nicest most reliable car i have ever owned. I mention this, as they used the same diesel engines in Audis, Passats, Golfs, Skodas at that time etc etc. All the quantities of extras still work ( I bought it near Sidmouth even though I am now in Dublin since 2004 ). It is also still on it's first clutch etc etc. and has it's orrigional exhaust. It does over 60 mpg on long runs. It would be hard to find a truly better car.
I think there have been a few back roomers who have

One backroomer to be precise and I think that's the only comment we ever heard from him/her. I would personally ignore this since it is one of those subjective, throw-away comments which virtually anyone could say about any car. Let's have some proper feedback.
FWIW, my brief experience of the 1.9 was much the same as my more extended experience of the similar Passat. If you don't mind a good throaty roar from the engine (not booming, or irritating, but nevertheless, there...) then this car seems good enough. But I don't know about mileage and reliability.
Good to hear of a flourishing high-mileage 2.5 TDI, as that'w what mine is.
The 1.9 TDI is the same engine as in other VW group cars, including the Skoda Octavia which is finding favour as a taxi. I'm sure I've seen plenty of stories of Octavias running up high mileages without missing a beat.
Another thing to look out for is Auto Gearboxes. My best mate had to have his replaced at 60,000 miles on his A4 and at the same time his colleague had the same problem. It was manifesting itself as noisy clunking at changes and then struggling to change gear smoothly. All replaced under warranty on both cars and might well have been an isolated issue. Worth paying attention to on a test drive though.........
I have a 2007 A4 2.0TDi 140 and at 50K it is really getting into its stride in both performance and MPG.
The previously mentioned engine woes of the A4 were the older 2.0TDI engines which had a non-gear drioven oil pump, mines a BRE so should be okay. Yes they are a bit noisy at tickover and externally, but as soon as you get rolling this is irrelivant.
I find many common rail diesels to feel a bit puny in comparison with the VaG PD unit.
I would say on an oldish A4 you need to look for potential clutch problems and obvioulsy cam-belt swap outs. Other than this, if the suspension doesnt feel strange or make any strange sounds you should be okay.
