A3 1800 Turbo Sport

[Danlam]

My wife recently bought an 03 plate A3 1800 Turbo Sport and when she brought it home I couldn't wait to jump in and take it for a spin. However, it is gutless after around 2000rpm and hardly has enough power to overtake - definately not what I expected from a Turbo sport!

Anyone tell me where to start looking - is this a common problem?

Hmmm. Perhaps a ******** turbo or disconnected pipe?

 

[Danlam]

How do I check for '******** turbo', is it something the dealer will have to do?

First port of call would be to check for fault codes, you don't need to take the car to a dealer as most decent independants will have the kit to read the codes but it would be advisable to take your car to a specialist in VAGs rather than a general garage as they will have more experience of the sort of issues relating to these engines...

I took it to my local garage (specialises in VW's, Audi's and Skoda's) who hooked it up to his machine. The readings resulted in a new Air Source Meter and Temperature Sensor, which improved things, but it is still flat - he's offered to have another look free of charge but I was wondering if there is a common fault that doesn't show up via the 'normal' channels.

I'm not expecting a mind blowing performance but my other car is a 105bhp Golf TDi and it is much quicker than this Audi!!!

I'd of said possibly the maf, try disconnecting it and going for a drive, if things improve then that's your fault, if they don't then you can definately rule that out..,

 

[Danlam]

At the risk of sounding thick, what is a 'maf' and where is it! My DIY mechanicing days stopped about 15 years ago when I got my first company car!

MAF = Mass air flow meter, and is found on a pipe coming from your airbox or cone with a connector on it

 

[JS1500]

No. 10 is the MAF.

(thanks to Westle for posting the diagram in his thread!)

Yeah sorry mate, the air box on the right of your engine bay has a fat pipe coming out of it, there should be an electrical connector going into the pipe, just unclip that and go for a drive.

You'll get a fault light come up on the dash but it'll go out when you plug the connector back in...
