Looking for some help please, the car is a 1990 500sl with ADS the suspension warning light has come on. The car has a 16 pin diagnostic and on checking the ADS slot got a reading of 4 blinks, this says acceleration sensor? The only sensors I can see are the ones which also control the ABS and ASR . But in spite of the warning light everything is functioning, ADS fluid level ok, car raises and lowers and also stiffens as it should. The pump is working and I am baffled at this stage any suggestions as to possible causes would be most helpful.
