RMcB

Thank you Airportable, that's very useful indeed.

I think that I mustn't have been clear about the SRS light though. I seems to work fine - I have no reason to suspect that the airbag is malfunctioning. The reason I mentioned it is that I understand that usually if the rotary coupler is broken, the SRS light will show.

I'm off to hunt for a MFU now...
