P38 - suspension pressure switch

Does anyone have instructions for replacing the Air Suspension Pressure Switch on a 2000 P38

My suspension "stuck up" and the auto electrician hooked the car up to his laptop to reset and it was reported that there was a fault in the pressure switch

Any help greatly appreciated

Thanks

Much as I hate to go against an 'auto electrician' I'm at a loss trying to think of one 'pressure switch' that would cause the suspension to lock-out at height and then refuse to answer to the height switch.

There are innumerable threads and posts on here about the suspension and it's quirks and I might suggest that you put the kettle on and have a good nose around. What you will find very quickly is that you can buy a connection lead and a c.d. (very cheaply) and then see what your suspension is doing for yourself, with paying an auto electrician.

Unlikely to be the pressure switch. More likely to be a height sensor giving a dodgy reading, it will eventually go to a hard fault and drop to the bump stops with the dreaded Slow 35mph message on the dash.
As dogsbody say's, download the free software from www.rswsolutions.com buy a cable and check it yourself. Or buy an EAS Kicker from Blackbox Solutions.

The air pressure switch fault can be a bit vague.It may be that the pump is goosed, or you have a leak somewhere. My advise to anyone with EAS problems is to do a valve block and pump re-build before doing anything else.

As rewmer say's pressure switch fault can appear for a variety of reasons, none of them to do with the pressure switch. First step is to identify the fault.

Had exactly this fault....turned out it was the driver pack at fault but that does'nt show up on the software......was from looking on here that i changed the pack...been fine for a year now.
