Car wont start,fans running and vag com issues?
mk4gti-t:
Great thanks for the advice. How do I go about disconnecting each device from the can? Ta. Oh and no work has been done at all. The only thing I did previously was to jet wash it the morning before it failed. I did wash under the arches quite thoroughly so water may have got in somewhere.
doylebros:
Start with the most common failure items ecu,instrument cluster etc and re-scan then check to see if the other items communicate with each other.
If its the ecu - then check the exhaust sensor wiring hasn't burnt through / was a common area if exhaust mods have been under taken.

Ok but how and where should I disconnect them from? Also the car is totally standard as far as I know so no exhaust mods have been done.
doylebros:
Most of the items just need unplugged i- f you can reach them however,not everyone is simple to get to!
The cluster is easy start there -

Just go to the section which shows the cluster being removed on the link and as I say rescan and see what shows up each time.
