Is it generally running poorly at all revs?
Running OK to 5,000 rpm and hitting the limiter?
Running OK sometimes and having bad days?
Starting OK?
Would be worth checking the codes if you can find someone with a scanner - ask in your local. Any VAG group scanner would probably work.
Its hard to explain really! When pulling off in 1st you have to give it some revs or it bogs down and takes a while, it seems to have nothing after about 4000k rpm? it revs upto the red line but doesnt seem to "pull" if that makes sence??
it starts ok, but if I rev it to say 3000 rpm then lift of the revs drop to about 100/200 rpm and sometimes will stall.
It has a de-cat and magnex stainless system and pops and bangs on over run some/most times
