Happy Friday to me!!!
So, story goes like this..
Problem started with 'Bing Bong' yellow suspension light, intermittent.
This then progressed to a situation where, when i would detatch a trailer, the rear bags would fail to reduce pressure once the weight was off the hitch, and the back of the D3 was in the air, nothing i tried would lower the back end, so i resorted to venting the lines on top of each back bag manually.
problem has progressed to 'Bing Bong Bing' and a yellow suspension lights, followed by red and a request to do 30mph max, oh and the back of the D3 goes into extended mode, but not the front.
Then (mostly because ive neglected to fix anything) yesterday, it decided to extremely over inflate the DSR bag, tho the point where the rear tailgate no longer lined up perfectly when shutting (i mean seriously, it was right up in the air!!)
plugged in and the following codes are logged:
C1A75 REAR RIGHT HEIGHT SENSOR MECHANISM
C1A13 PRESSURE DOES NOT DECREASE WHEN VENTING GALLERY
C1A06 REAR RIGHT HEIGHT SENSOR
Now, ive physically checked the sensors all round, all are attached correctly, and ive checked their positions in diagnostics and theyre almost identical number left and right on each axle.
Ive also rebuilt the rear valve block just inside the Passenger rear arch with all new o-rings. No improvement..
Any suggestions where to look next?!

For the price of a height sensor, I'd be changing it, at least to rule that out

Replaced the sensor with a known good sensor, tried to inflate from fully empty, still faulting as it seemed to be very confused about its current ride height. so i tried calibrating its ride height, this failed due to a crossvalve failing to do its job, now im getting a c1a00 control module failure, and the compressor wont come on at all.
Ive now rebuilt and cleaned the front and back cross valves, still has the same issue...

Compressor has probably burnt out through overload  It can when others can't,
It will when others won't,
It goes where others don't.
