Hi all, just after some advice really. Picked up my mk4 gti yesterday and the rev counter was working fine. After about an hour of driving i noticed it was stuck on just over 2000 revs. Upon stopping and switching engine off the needle just stayed on 2000 revs. I tried restarting and revving the engine and the needle twitched a bit and moved up to about 2500 and is currently stuck there. Has anyone experienced this before and can offer some advice please?
