My '07 GTI has just developed a stuttery misfire. I was driving up a slight incline in 3rd gear (DSG), part throttle at maybe 40km/h, eased my foot down a little further and just like that she starts stuttering away. Engine light came on, she stutters at idle and is hard to get off the line, but I managed to get her home ok
I'm thinking possibly vacuum leak but probably more likely a dead coil pack... any other suggestions? Anything I can do/check? Or do I just need someone with VAGcom(?) to diagnose the problem?
Cheers...
