This problem has come back...!
Basically it usually happens either if I rev it high out of gear (which i don't do!) or mostly when i park up and turn the engine off.
All the needles (petrol, speedo, oil) drop to the bottom, however the rev counter drops to about 1,000 rpm and then sort of twitches a bit and seems to settle between 0 and 1,000rpm. So when i start it up next time it (depending on tempreture outside) sits at between 1,500 and 2,000rpm
A couple times i'll go out the next morning and it will have dropped back to 0, but its doing my head in now!
So what do i do? Im thinking just buy a set of clocks from a breaking gti, as i doubt anyone would sell me just the rev counter.
Yeah...or neah?
