Nope, that's more likely to be the ECU relay, both that and the fuel punp relay should be changed at this age of the car regardless as they're a common fault. To be sure of diagnosing the problem properly you should get hold of vag com and give it a quick scan. You can always ask if theres anyone near you that will come and scan it for a couple of beers

had the same problem with my 8v. would drive fine the revs would die and pick up and then die, so on. and some times it would start up like it. turned out to be the maf sensor. if you can get the vehicle to do it at a stand still, open the bonnet and unplug the maf, if its the maf, when unplug the ecu puts a set vaule in and should run quick normal. hope this helps

Well it was nothing to do with the earth!!.
Cleared the engine speed sensor fault and started the car again, didnt come back straight away. Went out last night and all was good, but this morning coming down the motorway the revs dropped and picked up again.  :rolleyes:

Turned into work and the car died on me, then started it up again a couple of minutes later to go into my car park and it died right at the barrier!

Going to try the ecu relay next i think. Does anyone know the part number?

run another scan, if the engine speed sensor shows again you know what needs changing

I'm going to do that as soon as i get home, but i though i might aswell change the ecu relay as its like 14quid, Then i guess i'll have to get the speed sensor changed  :cry:

Update for anyone who is interested.

I have been home for lunch and did a check with vag com. No faults were found with the speed sensor.

I have also ordered a new ecu relay £11.38 from local vw dealer. I can pick it up tomorrow, so i guess its cross fingers now   :tongue:

probably an old fault code then, shame the ECU doesn't log a date when the fault was first logged
