Hi, I have an Audi A3 2.0T FSI Quattro from 2006 (200bhp model). A month or 2 back I chipped the car with the MyBlueFin machine to give it a bit of extra HP and Torque. The car has been running great until today when I went for a short drive.

When I started the car, it sounded a little funny, but nothing really to worry about. Then after giving the car a good clean with a jet-wash I went down town. On the way back up to my place (uphill) the car couldn’t keep its stationary revs of (1000rpm) when i had to stop and i saw the needle jumping all over the place. Eventually after a few seconds the engine cut out. I managed to get the car starting again within a few seconds and drive home.

When i parked my car the same thing happened again, and the engine cut out.

Now i remember that a week or so ago I also saw that the rev needle was jumping around a bit when the car was stationary (900rpm - 1300rpm, instead of steady 1000rpm), however back then I didn't cut out.

Any idea what the problem might be? Do you think it has something to do with the fact that the car has 40bhp extra now? I do run the engine pretty hard (often full speed on motorway, and rev to 6500rpm while accelerating.)

Thanks very much for your help.
