AUDI A6 2016 NO LIGHTS ON A CLUSTER,NO ABS AND NO POWER STEERING

[Tomas0710]

Hello everybody.Hope to get some fresh ideas from you,guys..I bought a Audi 2016 2.0 with electrical problem.Auction described as power steering problem.But later found out that cluster doesn`t work and ABS also.I checked with a scanner,says no communication with a power steering module,ABS,and instrument cluster.I can start the car without cluster..! I thought Audi has immobilizer inside cluster. Today I tested CAN BUS numbers,they are ok.All fuses are ok.Car runs and drives.Wow..

I'd start with the basics, check the grounds and the voltage at each thing that isn't working.
