CAN Issues

[nator187]

I'm trying to track down the culprit for these codes that consistently return after I clear them. I've done some research and inspected the CCM already. I see no signs of water damage or corrosion in the plugs, on the pins or on the board itself. When I drive around the block with the VCDS watching 19-CAN Gateway the connections seems to be intermittent at times. Same thing happens when watching the 03-ABS Brakes. I was watching the brakes because occasionally I see a check brake wear message on the dash but no codes in VCDS. Any ideas?

Side note, the windows don’t roll up/down anymore and the interior lights do not come on.

Found a broken wire in the loom south of the CCM and the orange wire joints were corroded. Repaired both and all is well.

I had a good thread you might check out on CAN wiring. It applied to B5.5 but most likely the corrosion issues are pretty much the same especially arround the CCM.
