Hi all, wife got a power steering module warning but still drivable, by the evening it was a total failure. Trouble code :- B20000 Ctrl module faulty, B200049 Ctrl module faulty and a C10AD29 sensor for motor position intermittent. In another ODB section we also get a 01309 - power steering control module trouble.

I have removed the module unit from the nbottom of the audi, it "looks" fine with no signs of water ingress. Does anyone know what the end letter means on the part number 8K0 909 144 (B) and (J) Trying to find someone who reconditions them, how important is te end letter. Anyone got any advice. Is it likely to be this moule or should I concider replacing the lot, Car is a 3.0 v6 tdi. 2014 with 190,000km on the clock.
thoughts?
