Before Pedro asks - I assume that it was a diesel?

Suggests a fault at the TC ecu as the TC ecu is a gateway for the high speed can-bus. Look for corrosion on the TC ecu's pins.

The suspension ecu's can-bus passes through the TC ecu whereas the gearbox and engine are on the other side.

So is something like contact cleaner good to use on these ECU connections.

I had this fault reappear today, 7 days after I left the car on battery charge over night.


I removed the battery and tried to check the ECU pins, could get at the front ECU no problems , all nice and clean , How the hell do you undo the back ECU connectors on the top.

There's a little clip you need to push on, then the lever will swivel over and push the connector out of it's socket.

They need to be done in order, right to left I think..

Great just what I needed, a challenge.

When you know the trick Ean, it's very simple!
