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
