Hi All,
My car has suddenly lit up a load of warning lights as follows:
ABS FAILURE
PSM FAILURE
CHASSIS SYSTEM FAULT
START STOP MODE DEACTIVATED
FAULT ELECTRIC PARKING BRAKE

Does a fairly simple defect activate all this lot (such as faulty pad sensor or faulty abs sensor) such that my local garage can resolve? Or does it mean a mandatory trip to see Nelson (Nelson Maindealer :) to have my wallet surgically removed? Advice gratefully received!

Thanks,
Chris.
 
It sounds like you might have a faulty battery. I had a similar recent experience with a 991 and the battery needed to be replaced. If you are still able to start normally after everything has lit up then it is probably not the battery - this may sound confusing but all I am trying to say is if everything "lights up" unexpectedly it can be a battery issue (but then you usually have a flat battery at start up as well). Maybe charge up the battery on a trickle charger/conditioner and see if that clears it (and if charge holds).
 
Thanks Keith but car starts and runs fine and has just had circa 200 miles put on it this last w/e. These fault codes have been coming up on start up for last week or so (and look like they are here to stay until I do something about it!).
 
Hi all,
Problem now resolved and car collected today. Yes, it was a failed front ABS sensor and all the warning lights that lit up were in some way brake related. They also changed the wheel bearing as the abs sensor picks up a signal from that and they have to be replaced together. They tell me Mercedes and BMW now use the same system.
Total cost £375.02 using a local independant.
Thanks for your help guys!
Chris.
