Hey I have a 01 s500 i did a lot of work to it I have this car for 3yrs now when I first got it I changed the 2 front air shock ,air pump ,and the valve block ...well yesterday the airmatic visit work shop came on n the ride is stiff the doesn't drop at all don't now what to do plz help remind I have new front air shock n pump from arrnot and valve block
Also the rear right air shock the dust boot is broken but the car doesn't drop
The pressure relief valve is a part of the pump so it sounds like the new pump is faulty. But you really need to read out the fault codes to pin this down.
The pumps works fine .u think is the rear right shock ?when I was doinh my rear brakes I seened the right air shock dust boot broken completely but the car doesn't sink
If the right rear air shock was damaged the car would sink overnight on that corner, it does not sink but rides high which means there is too much pressure in the system, only two things can cause this, 1 the control unit and 2 the pressure relief valve on the pump.
