Hey guys - owned the s3 for just a couple of weeks now and had it at an Audi specialist to have certain things done. Had an oil change service, CV boots replaced, new brake discs and pads, thought all was well.. BUT, I picked the car up on friday - was taking it easy cos of the new brakes and car was running perfectly. Parked it for the weekend and only drove it again this morning. Now, the car is shuddering like hell - especially under harder acceleration and it feels like there's no power AT ALL. Even the dash shakes. I have no idea what the problem could be. Heard of limp mode - but I'm new to the s3 so I have no idea if that's the problem. I'm sh!tting myself now - anyone know what could be wrong!? Thanks, would really appreciate some help.
