Hi, I'm new here but I've had a Golf for a couple of years now. The thing is, lately the car has been running really badly when it is hot. I have taken it to a local garage who say there is no diagnostic port and a good friend has had a look too. My mate knows a bit (he runs 300hp rally cars and builds specials) and he can't find a port either. He doesn't know much about Golfs though, his last one was a Mk2 more than 10 years ago. The car runs OK when cold but when up to temp. it splutters and loses nearly all power. If I put my foot to the floor it clears after a while but still seems under powered and the problem comes back almost straight away. My friend has checked the AFM, the compression and plugs leads etc. He thinks it may be a faulty sensor or broken wire.
What do you guys think? About the car that is!
Cheers Lauren.X
