I have a 2006 SL350 and reasonably regularily, the SRS light comes on along with a number of other faults. Usually, if the car has been standing for a number of hours (possibly overnight), it will be O.K. when started and run. If the car is then turned off and then on, the fault is likely to, but not definitely, return. The problem seems to be water (or damp) related. In the winter, it was much much worse than now and washing the car seems to trigger the fault. When there is a fault, the red SRS light always comes on. It is accompanied by one or several of the following. - The airbag light on the glove box flashes rapidly - Windscreen wipers or washer don’t work - Comand system says it is unavailable and turns off - Rapid clicking sound in the courtesy light cluster at front middle of roof - Seat (probably the passenger seat) clicks rapidly - The amber roll bar warning light may come on for a while and then goes off - Possible issue with Auto mode headlights not switching on Usually, if I drive the car for 20-50 minutes the faults clear. I took the car to specialist who clearly knew what they were talking about and they re-plugged all 3 SAM's and checked for water ingress / corrosion - none was found. They reset all of the faults with STAR. Fault vanished for about a week and then came back (mind you, it was was warm and dry weather) SL is a lovely car but the fault does deminsh the ownership experience ! Does anyone have any ideas and how I can get it fixed?
