Re: Golf GTi check engine light
What year is your car? I heard there are some problems with 08-09 Audi/VW 2.0 TFSI engines, which is related to the camshaft adjuster.
My audi had the problem, just out of workshop for 1 month. Same problems you are complaining about.
Luckily under warranty, so in total they changed the camshaft adjuster, cam shaft, intake manifold. Lots of work!
better get yours checked... it is actually a service recall by audi.
