Control module adaption:
After replacing either the ESP/SPS control module (N47-5) or the brake booster (A7/7), it is absolutely necessary to perform an adaption of the ESP/SPS conmtrol module (N47-5) as well.
The ESP/SPS control module (N47-5) has to learn the values for the BAS solenoid valve (A7/7y1), see HHT menu.
In case of complaint, and no fault is present in system, perform 23 in its entirety.
