    I have a number of what I would consider to be CAN bus connection/communication issues and wanted to inspect the loom in the areas of junctions/joins.

    I have a wiring diagram, but am not sure of the routes of the wiring and where the splices might be. I understand that there are some on the drivers side sill area under the carpet and this is a common problem area?

    I physically checked accessible connections to the ABS, EEC, central convenience module and the instrument cluster, I would be grateful for any pointers to common failures in these areas. Recent history of the car is one year stored in damp conditions, mildew evident in car, now mostly dried and cleaned, but I suspect moisture ingress to be the main culprit. Plenum chamber had an estimated 1L of water, so probably more at one point and likely to be cause of damp carpets.

    Auto-scan attached to show the current issues.

    The front passsenger footwell is known problem area where water ingress can corrode wiring....worth lifting the carpet as it's not always obvious that it's wet underneath.
    I assume you have cleaned the plenum drains behind the wheel arch liners?

    Yes, plenum areas drained, as that's where the water was found. I'll have a look under the carpets and provide feedback.
    So are you saying both footwells have problems on these cars, or is it dependent on which side the steering and controls are?

    Yes both sides, behind kick plates and below carpet. Passenger side seems more common, perhaps simply because of road camber when parked. The harnesses will need to be opened up going forward to reveal splices. Not saying this is your issue just common areas for electrical
    gremlins.
