So I have a 2013 gti that is stage two. Cars been stage 2 for about 2000 miles now and everything has been fine until about a week ago. I've been hearing a strange clunking sound from what sounds like the gearbox or even below that. doesn't happen all the time but when it does happen I can feel it in the pedals. mostly the clutch and brake sometimes the accelerator. No clue what it could be wondering if any of you have had this happen and know of possible fixes or what the problem might be. Any help would be awesome.
