Help! I have an intermittent fault with my air bag system (Ulysse '98 2.0) - the condition indicator. Sometimes it flashes, some times it stays on and other times it goes out as expected. So for the MOT last week, I drove her there with no illumination, and drove back after with no illumination. But, for the test, it stayed on! (for ref - it illuminates as normal during engine on/start). Where to look first? Thanks.

The first thing to do is to remove the airbag and spray the connectors with switch cleaner and then refit. I have successfully cleared several doing just that.

Failing that a new comms2000 unit.
