Hello all,
I need guidance for troubleshooting a CAN BUS wire short on my 2010 Audi Q7 TDI. It has a lot of options, so there are quite a few electronics. Can someone please advise me of the recommended troubleshooting procedure, resources (i.e. diagrams and list of cable runs to be checked) as well as any way to isolate the specific area where it's broken? Here's the section of code reporting the CAN bus problem:
