A4 2.0 TFSI common problem

Hi all new member here, hope this is in the correct place (I've also put it in the tech section). I was intending to buy an Audi A4 2.0T FSI Quattro S-line after looking for the perfect car for the last 4-5months. I've always been lead to believe that the 2.0 FSI turbo unit (as found in the Golf GTI) is very very reliable. However, after reading the article on page 19 of Audi Driver June 2007 (Issue 6 Volume 11) entitled Mysteries of the 2.0 TFSI I'm having second thoughts. The article discusses details of a 'common fault' around fueling which can cause the car to hesitate or for the ECU to put the car into limp mode. This is then cured by either running a test on the ECU and replacing the regulator or replacing the regulator and pump. I was wondering if anyone could answer the following questions for me:

Is this really a common fault have people experienced this problem?

Is it something that would be covered by the warrenty?

Which year of models does it effect?

Is there a proper cure, recall or mod as it sounds like it could re-occure every 15,000miles?

I would really appreciate peoples views on this, as I'm not keen to invest a lot of hard earned cash if a fault exists with this engine.

Any other comments about positives or negatives of the model would be appreciated!

I've had two 2.0TFSI special edition s-lines since March 2006 and have never had any problems nor have heard of any like you describe.

If it was a fault with the regulator and/or pump then it would be covered under warranty as would any ECU recall.

The only recall I've had was an ECU one recently which was for spurious error messages 169144-ok.gif

11,000 miles on my S-Line Special Edition and no problems here. The way I understood it, it was more likely to affect tuned cars that demanded more fuel and the pump/rail couldn't deliver sufficient fuel at a high enough pressure.

I really wouldn't worry about it. It'll be covered under the Audi warranty (assuming you haven't tuned it - which might give them a get out) and if it does become an common problem, they'll need to issue a recall/rework to solve it.

To be honest I wouldn't even use Audi Driver magazine as toilet paper...

Why do you say that? I think it's quite a good magazine. Just as well really, seeing as it appears to be the only independent Audi magazine again - TotalAudi seems to have died on its arse before it ever really got going. frown.gif

This problem was an ECU map problem and has been rectified in an update that started rolling out through the dealer network around 2.5-3 months ago.

I wouldn't let it stop me from buying one at all.

And I also think that Audi Driver is a great magazine (plus my mechanic writes for them) 169144-ok.gif

The biggest issue I have with it is that there information is always about 6 months out of date and usually in accurate. If I remember correctly they were complaining that the radio's in the A3 didn't have MP3 CD Compatibility...and this was only in an issue from about 2 months ago!!

Thanks for the responses. I take it none of you would let the article stop you buying one then? Think i'll take it for a test drive at the weekend then!!!

Mate, they're built like tanks. I've treated all my Audis like crap, but never had a breakdown!

I've had plenty of punctures, broken windscreens etc - but thats not really their fault grin.gif

Fair enough, I've had wiper blades fall off, broken glove compartment hinges and a few other bits and bobs - but wear and tear with high mileage occurs on all cars.

If you like the car, don't be put off by apparent "reliability" issues. They're as good as the competition and some. (except jap cars of course - but they look shite and the interiors aren't as nice)
