Steering Angle Sensor needs calibrating?

[phil7132]

Having replaced a faulty Steering Angle Sensor or "Squib" I now find that my airbag warning light goes out when erasing the fault code but immediately comes back on. This is now joined by both ABS & ESP warning lights and red handbrake warning light flashing. After contacting local VW breakers was told that the newly installed sensor would need calibrating to the ECU and referred me to an Auto Electrics specialist. I know that the VW breaker has VAGCOM diagnostics and so assume that this is not something that can be done using VAGCOM as he referred me elsewhere. The mechanic who fitted the sensor said that he has fitted these sensors in other cars previously and they have never required calibration. Can anyone verify what I have been told and also if this is something that can only be carried out by a specialist?

Cheers

Are you driving the car mate ? You need to drive in a straight line for 10-20 meters before the fuzzy logic resets itself !

I had to do mine a while back, you (obviously) need vcds, then perform the following:

Basic Setting


Sensor for Steering Angle (G85)
Important Note: This applies only for Models with Conti/Teves MK70 ABS/ASR. For Conti/Teves MK60 ABS/ASR/ESP look at Vehicle specific specific Procedures in ABS System documentation.
Prerequisites:
Start the vehicle.
Turn the steering wheel one turn to the right and one turn to the left.
Drive in a short distance straight line on a level surface at a speed not higher than 20 km/h.
If the steering wheel is straight during the test drive then stop the vehicle with the wheels pointed straight.
Ensure that the steering wheel is not moved again.
Keep the engine running and do not switch off the ignition.
System voltage at least 12.0 V.

oops! Just realised, the above may only be for a b6...
