If the old Control Module is still accessible read/copy it's Coding to the new Module.<br>
If a complete [https://www.ross-tech.com/vcds/tour/autoscan.php Auto-Scan] containing the original Coding of the Control Module is not available Coding information is available while connected to the vehicle with VCDS using the '''[http://www.ross-tech.com/vcds/tour/recode_screen.html Long Coding Helper]'''.

* 40168 = Basic Setting Enabling


== Basic Setting ==

=== Steering Angle Sensor (G85) Calibration ===

'''[Select]'''<br>
'''[16 - Steering Wheel]'''<br>

Turn steering wheel at least 30 ° left or right and back straight ahead (Tolerance: ±0.5 °).<br>

'''[Security Access - 16]'''<br>
Enter 40168<br>
'''[Do It!]'''<br>

'''[Basic Settings - 04]'''<br>
Group 001<br>
'''[Go!]'''<br>
Activate the Basic Setting.<br>
'''[ON/OFF/Next]'''<br>
After a successful basic setting, field 3 should say "OK".<br>
'''[Done, Go Back]'''<br>

'''[Meas. Blocks - 08]'''<br>
Group 033 Field 3 (Steering Angle Sensor -G85-)<br>
Specification: 0.0 °<br>
Tolerance (when straight): ±0.5 °<br>
'''[Done, Go Back]'''<br>


Notes:
* To confirm the status of the G85 calibration see MVB group 032.
* If the basic setting group results in an error message verify the live G85 reading is  ±1.5 °.  Readings such as 359° would indicate the slip ring is mechanically out one full turn.
* The slip ring is the 16-Steering Wheel Electronics module.  If the vehicle deployed Airbag(s) and the slip ring was replaced make sure the module is [http://www.ross-tech.com/vcds/tour/recode_screen.html#long long coded] using VCDS.
