I think the earth is bolted on the top right on the rocker cover

What age is it ?       If its the later mk2 , and I remember correctly , if the rev counter and the warning lights and I think the MAF don't work it could well be the printed circuit in the dash which comes with the rev counter in one unit  complete ( If my memory is correct ) fairly common on the later mk2 golf gtis  .

Hi,
I've got exactly the same problem on my 1990 8V GTi...

Previous owner claimed that "sometimes" it would work, sometimes not, the car runs fine otherwise -
just no tacho, MFA or oil pressure light...

Which fuse needs to be removed to reset and what is it rated at, please?

thanks in advance,
J.

Unfortunately , from what you're describing I think you need to replace the printed circuit which includes the tacho to cure this fault .
 I have changed a few on the later mk2 GTIs and they had exactly the same symptoms as yours.
I honestly don't think reseting will cure this problem

yeah i would agree if the mfa had just gone then it might be ok however you can  get clocks off ebay for not loads of money

nah definately try the fuse all the things that are gone on yours is what happened to mine i think it was the 4th from the far en (the drivers door end) but check what it says think it was on with interior light but you will see your clock go out when you have got the right one! hope it works for you mate!

I have the same problem. I pulled the fuse out but that didn't work. Do you have to leave it out for a certain time? I think I will have to replace the tach part of the dash. Does anyone know a site with a decent FAQ step by step guide on how to do the dash?? I think this is quite a common problem.
