I have a 2007 VW passat v6 with a intermittent power

Customer Question

Hi i have a 2007 VW passat v6 with a intermittent power steering issue. This is an electric power steering system. I have a 00778 Steering angle sensor g85 no or wrong adaptation code and a 00569 steering motor current circuit open. This vehicle has come in 3 times with the same problem. The past two times i have cleaned all fuse connections and ground connection under the air cleaner and around the fuse block. Each time i have regained power steering. We gave it back to the customer and a day later he has the same issue. Today we unplugged a connector and plugged it back in and we regained power steering. Not sure where to go from here for a solid fix? Could it be a simple angle sensor replacement or relearn? Any advice?

Hi Im David, what connector did you unplug? do a steering angle sensor calibration. if that doesnt work replace the steering angle sensor

Customer: replied 10 months ago.
It is the connector going to the steering motor on the rack. It has about 6 wires. We unplugged it and plugged it back in and it seemed to work. we will try the calibration and get back to you

Vehicle Information


Steering System, Adaptation Requirement after Replacement Part Installation

Technical Background

Service parts are shipped with a software mapping default and have to be adapted to the individual vehicle requirements.

Production Solution

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.


Prepare by getting the vehicle PR-codes for suspension (i.e. L04, G05 etc.), park assist (i.e. 7X5, 8A3 etc.) from the trunk of the car or ELSA.
Depending on optional equipment more or less PR-codes may be needed.
