Removed the h&r cup kit on the X5 and reinstalled:

Air compressor
Air accumulator under car
All air lines
All 4 air bags


Air suspension switch led us illuminated but doesn't raise or lower car, it just flashes and then goes solid

I can use INPA to manually raise front axle and lower it.
I can use INPA to manually raise and lower each rear corner

All 4 level sensors show working however front right shows slight deviation in height and voltage. Not sure if that means I need to try rotating the level sensor bracket some.


I used pa soft to check the ehc2 module and it has 2 codes but Google isn't helping me much.

Anyone have any idea what they are?

Code 22[034] Reservoir-pressure-sensor
Code 23[035] Supply Reservoir-pressure -sensor

I can figure out if this has to do with the air accumulator I'm here the car or the air compressor itself.
