got some issues with my girlfriends tt, it has a bad splutter under load/boost, at its worst in third gear about 3000rpm which at times makes the eml light flash. I've plugged in vcds and it just came up with random multiple misfire. It had new plugs about 5k ago. Wired thing is, it's smooth on idle and drives well when not booting it!
Was just curious if there was a common fault that may cause this?
i was thinking coils, but would have thought that would be a constant misfire on idle ect
or maybe a maf? But would have thought that would flag a fault in the memory?
only other thing there was an old fault that cleared and didn't come back, relating to the inlet cam sensor.
cheers for any help given!
