Mk3 gti cabriolet 8v aag engine cutting out problem

[Hongkongphooey]

I had a similar problem with my 8v run around.

Replaced HT leads, rotor arm and something else I can't remember after a few beers! However that wasn't the cause.

Clean the throttle body thoroughly and you should be fine. This won't show up on any vagcom fault codes bit will save you lots of cash.

Try it

dirty TB won't cause short to plus fault.
it's either hall sender or the wiring.... wiring can be found out with multimeter, hall sender itself can be tested but if the fault is intermittent it's more difficult.

Does the oil light flash, if so this is the crank angle sensor, had exactly the same problem with mine.

Try this run your golf up to normal temp turn on every thing ie wipers heater lights and electric rear window run the engine above 2,000 revs and then put a multi meter on your battery if it goes bellow 12v then cutts out when the fans cut in it could be your alternator output if you have clamp to read the amps even better.
You did say that the fault cleared then happened 40 mins later when the fans cut in
Just a thought

problem with the hall senders is they break up when hot causing miss fires/stalling etc and will run fine when they cool down again, wiring is normally a less intermittent fault but still worth checking as the wiring becomes brittle with age!

I can supply a delco (reman) unit for £189 delivered exchange or a budget unit at £105 exchange (both have 2 yr warranty)

Has the timing been done recently?
I always check this when I get a hs fault, if the dizzy is out it shows as a hs fault.
Your showing a short so it most likely is but worth checking

I think mine has the same issues.

1995 Mk3 2L 8v.

Warms up nicely till it gets to 90deg c. If you rev it up slowly and take your foot off the accelerator, it dies.

I've replaced:
MAF
Temp sender unit
Fuel Relay
order a new Hall Sensor - coming on monday

Found the coil pack has a dodgy earth strap. Where can I buy a new one? Could this be the cause?

[gasketface]

Could be coil pack itself.

You could make an earth strap out of a bit of amp power lead with a couple of crimp connectors,if not a good motor factors will have one.
