Passat 2005 130TDi estate:
Have had airbag light on for a while. I have had airbag light on issues since the dreaded water in the footwell issue from the blower inlet some years ago. In the past I have cleared it with VCDS and it generally stays off for months/years. However this time it will not clear. It is

01222-crash sensor side airbag passenger side (G180)37 -Faulty

IS this the sensor under the passenger seat or is it the SIPS sensor in the door and is it likely to be the sensor, the wiring or the CCM connections (as that must have been damp at the time). Don't want to rip out un-necesssary trim. Any suggestions or tips welcome as MOT is due in 3 weeks
