Couple of weeks back my standard mk5 GTI decided to aggressively limit the revs at about 3700, almost feels like a rev limiter kicks in and the revs drop very quickly! Drives fine up to 3700rpm with no other symptoms. It seemed to have resolved itself for a couple of days and has now started to do it again, any ideas??
Checked the fault codes and these were stored:
00051
00049
01112
00581
01089
12555
We cleared these, took it for a run and the problem was still there, but when we checked for fault codes again there were none?
Any help would be massively appreciated
