My s3 has suddenly developed what i can only describe as a misfire, if i build the revs very slow then it seem ok and revs pretty freely in neutral. The problem is if i want to accelerate or drive fairly quickly.
Power is lost and the car judders, i can also hear chattering as though i was backing on and off the throttle.
My technical knowledge is pretty much zero but there was a lot of talk of the standard diverter valves failing, could this cause it?
Or could it be something like the spark plugs or coild pack?
the car is a 2007/57 s3 with 25k, was serviced a while back at Audi and has been running fine.
I am using GIAC software and the Evoms so am in two minds weather or not to go straight to Audi or try a local garage and see if anything shows on a diagnostic check.
Any ideas or advice would be great so i can pass it on to the garage.
Thanks
