Steering System, Adaptation Requirement after Replacement Part Installation
Service parts are shipped with a software mapping default and have to be adapted to the individual vehicle requirements.
No production change required.
Follow the Guided Fault Finding instruction of VAS 5051B/VAS 5052 tester, and as outlined in this technical bulletin. The CD will not work with the
tester VAS 5051A.
TIP: Non observance of the following points may lead to control module failure. VAS 5051B or VAS 5052 must always be connected to the approved
power supply at the approved voltages. Under no circumstances should the power supply be interrupted or the diagnostic connector unplugged during the
flash procedure. Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.
Connect vehicle to approved Volkswagen battery charger Midtronics InCharge 940 (INC940) tester/charger to maintain proper battery voltage.
Insert CD, Part No. W42RACKMAP50 with steering rack adaptation files.
