Audi A6 C7 coolant leak into mechatronic wiring

My 2012 Audi A6 3.0TDI quattro started showing engine malfunction error. Found out Mechatronic plug in wiring had coolant in it. I cleaned it using contact spray and plugged it in again. After 2 months there was coolant present again in the same part. Recleaned it again and now I get steering mulfunction,TPMS and ESP errors and steering becomes manual. Reading in forums I see that the coolant solenoid valve above mechatronic wiring is a known problem in this car by Audi Bulletin TSB# 2033806/7.

Every time I accelerate hard I get steering errors. I also have a consumed engine mount but I dont think it relates.  Do you have any solution about this problem as noone knows anything about it including audi. 

Diagnostics shows no errors but coolant valve error.
