L322 L322 stuck in extended height

Good morning all
After some help with my trusty old 2003 TD6, currently stuck in extended height.
1st issue was a failed steering angle sensor. fitted a new one and registered it in iiD tool. working fine, values updating with steering wheel turn.
Car had been parked up for a couple of months, close to the house. 2 flat tyres sorted. Car then went into super extended height and has been there ever since.
Replaced 2 x rear height sensors as one had broken away from the rear arm.
It doesnt sound as if the compressor is running at all, ive played with the iiD tool and even tried to deflate reservoir/test valves/deflate all, but nothing. iiD goes through the motion and after a minute says 'operation complete', but nothing vented.
on the iiD tool choose 'reactivate EAS' and it says 'operation complete' within a second or 2, so it must know the system is already pressurised.
Sintered tip has been drilled out.
New compressor and relay fitted.

Guided calibration doesnt adjust anything. Measured its physical height and each corner is approx 640mm from centre of wheel to wheel arch.

clear codes and re-scan with iiD and get 3 codes that are not really anything to worry about.
IP - Instrument Pack 0x0011 Unknown.
IP - Instrument Pack 0xBD EBV function fault recieved from ABS ECU (i think being a 2003 its an old legacy code from BMW)
PAM - Parking Aid 0xC Front sounder off

Desperately need to get this fixed, so any advice or things to check greatly appreciated guys.

I don't know much ab out the L322 but I do know that turning the steering from lock to lock is required to reset things sometimes.

I had my L322 stuck in the air like this too. Question is, "what the Bl***** hell caused it?"

From memory, I could deflate it with GapIID but not with the buttons and I had a lot of issues with the connector plug on the compressor itself where it kept disconnecting in spite of it going on with an audible click and not being able to pull it apart by hand, it would simply remove itself and I'd open the cover to find it completely separated again! When that happens though it would throw a fault.

I'm wondering if you have fitted the right compressor? Is it an AMK? I know you can change them on the later cars but you need to code the car to tell it which one you have.

Instead of trying to deflate the car, if you go into the Service/Test (or it might be Height) functions, can you manually lower the height of it there? It's the bit with the pictorial of the car and the arrow buttons. I can't see it in demo mode and I'm not near the car to check. When mine was stuck, that still worked.

It's awkward to test the compressor if it's at full height as it's not seeing a pressure drop so it won't kick in. Being an early one, is there a valve in the spare wheel well that you can use to release some pressure? I've never owned one of that year but I think I recall seeing something along those lines. Obviously exercise caution and make sure you're wearing ear protection as I can attest to the noise level when it deflates!

Whereabouts are you? Someone local may be able to help out if you put your rough location on here
