Hi,

I have an N reg 1.8T, about 6 months ago the turbo blew, have had a long running saga since. I had a new one fitted by my local garage, this turbo was faulty so they replaced it with another then a bit of exhaust blew, then the next bit blew, both replaced.

Now I have a problem when I accelerate hard, if I stick the pedal down the car suddenly loses power and sounds / feels like something is about to snap, if I take my foot off the pedal and apply again lightly it continues fine. The garage first fitted a new "temperature sensor", this didn't fix it, they have just fitted a new "diaphram", this hasn't fixed it either - they are now scratching their heads... They can replicate it but it doesn't give out any fault codes.

I confess I don't really know much about engines in the slightest but if anyone can suggest something I can suggest to the garage I'd be extremely grateful as this is driving me mad now! Is this time to take it to Audi? I've already spent a fortune so would really rather not....

Many thanks,

Nick.

have you tried unplugging the MAF, if it drives better with it unplugged then that's the culprit, it's a fairly common fault

nick . where do you live ?

East Grinstead in West Sussex, according to the garage its not the MAF or it would be doing this all the time, it's only when i press the pedal down more than half...

Thanks for the suggestion tho...

Are you getting fuel cuts ?

Car suddenly cuts out with a bang then cuts back in.

My old evo used to do it occsionally caused by overboosting of the turbo.

Usually caused by a change in air filter, exhaust etc... ?

Never heard of that on a real car lol. Sounds like the car could be going into a form of limp mode??

What fault code does it have ???
