Driving home last Thursday, went to accelerate and boom, judders and vibrations and one poorly sounding GTI with engine warning light flashing away.
Came straight on here and read up, sounded like a coil pack failure. Had a busy weekend planned and having read about the VW re-call I realised it wasn't going to help me get back on the road asap. So a quick trip to Euro car parts in the furby and I have a new coil pack... I don't claim to have any mechanic skills but through brute force and ignorance managed to swap the failed one (it had to be the 4th one that had failed!) Problem solved!
It's probably a very simple job for all you experienced mechanics, but I'm chuffed anyway!
Big thanks to everyone who has ever posted about coil packs, I've probably read every post going!
