4.8is Reinstalled air suspension system and have 2 codes.

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.

im going to take a wild ass guess that the 2 codes indicate that the Accumulator Pressure sensor on the valve body on the accumulator tank is bad.

looks like that sensor is around $130 dollars online so ill order one of those.

my compressor has been rebuilt with Bagpipingandy repair kit. at least that's what the receipt in folder i got with the car indicates.

i have another complete stock compressor turtle shell assembly from a 4.4 that had 4 level air suspension as well i can always throw that in to try it.

wpoll will become famous soon enough
Also, when the air susp. was removed, was the EHC option removed from the vehicle order?

If so, it may not work, even after sorting the errors.

From my understanding they just used PA soft and went into the light control module check control area and unchecked suspension inactive option and I went ahead and read enabled that option. And now I get the suspension level inactive message on the check and troll because of the error in the EHC module for the accumulator pressure sensor.

I suppose I could check the vehicle order in NCS expert and see if it's still there.


I went ahead and ordered four new arnott bags front and rear for sport suspension. I saw some DIYs where they said you could reuse your front struts and just replace the air springs

I also ordered a new accumulator pressure sensor, 4 new ride height sensors, 8 new airline fittings with o-rings,

I'm hoping throwing all this at it will help alleviate the issue

All the airbags that I had in my box from the previous owner had date codes of 2013 so I assumed they would still be okay since they weren't original. They were newer than original but there are definitely leaking because overnight the driver side will be lower than the right side.

I'm having issues with my air suspension as well, and I'm not going to throw thousands of dollars at it...Everything I've read online says I'd be fighting an uphill battle. What was wrong with the H&Rs?
