This gave me loads of grief and took ages to find, the CAN high was be dragged down by the engine bulkhead harness, it had dropped down from its securing points onto the back of the engine and had started rubbing through. God knows why Peugeot have so many colour changes for the high speed CAN system, plus on this model there is a CAN interface fitted in the nearside wheel arch for the radar. All done now so happy days
