ABS BAS EDL visit workshop! after pressure wash!
After cleaning the wheel arches of the car with a pressure washer there were initially no problems... I think the abs and airmatic wiring got very wet. I drove about 10 miles and then the abs applied itself under light braking and at very low speed followed by the above warning. I also lost parametric steering... at town speeds I still had pas but it was much heavier. The car seems to reset itself immediately after a start, but the fault has happenned a couple of times. Any ideas which connectors I need to look at, clean or dry out with some heat? Maybe I should apply a water dispersant spray to them? Any thoughts would be appreciated!

Most probably the pressure wash did something to the sensor which is picking up the wheel rpm controlling ABS, BAS, P/S, ESP and others. It is a sensor counting pulses. It is right on the hub behind the brake rotor. It can be that the cable got damaged and miscounts the pulses, or the (small) distance between the sensor and the hub has been filled with residue and causes miscounts.

Hard to tell, what to do. But I would suggest to first remove the wheels and try to dry/blow the hub area with compressed air. It may be the fix already.
However, if the fault messages appear randomly, the very first to do is to turn the steeering wheel (engine idleing) from one extreme to the other and back. This sometimes clears faults originating from miscounts of the sensors, because the systems (e.g. BAS, ESP, ABS, ...) require an accurate angle position of the wheels, and turning the steering wheel sets this on default.

Thanks for your advice, turning the steering does seem to reset this when the fault occurs. I'm hoping the fault has sorted itself out, no reoccurence on the 15 mile journey after it happened twice within 10 miles!
It's really scary losing the parametric steering around town... the steering wieght up dramatically and you have to turn the wheel further or so it seems to get round a corner!!!
