Sorry by reviving this old topic, but it is better to write on existing one than creating 1000 of same issue..
Would love to know if the issue he fixed? I have nearly same situation, but little bit toughter...

While car has ERRORS on ABS brakes RED and ABS, - commutations between all modules (except ENGINE and AIRBAGS) are gone. Can't read any codes or do live data. Speedometer doesn't work, all units looks like working. Today turned car on and ABS light gone, so instantly checked the codes are stored, and found communication related trouble codes. Anyone can help me? Can't find anywhere the CAN commucation line scheme, where it is located, wanna check wires there. Also Once everything get back to working, it stops after first brake pedal press on snow (with a little slide), ABS turns back ON red STOP also, commucation lost again between all modules expect Engine and Airbags.

Anyone can help me out? It is Wife's car, and during winter I must ensure her safety drive.
