2004 XJR suspension problem after repairs

I've unsuccessfully searched the forms for a similar problem.

I have a 2004 XJR with about 120k miles. Due to a leaking front shock, both front shocks were replaced with Arnott units. An air suspension fault continued to show up, and the repair shop diagnosed a faulty air compressor.

The air suspension fault code cleared after compressor replacement. However, I noticed the following day that the passenger side of the car - both front and rear - was significantly lower than the driver's side after sitting for 30 minutes or longer.

Opening a door would immediately cause the passenger side to raise to a normal level. No fault codes would appear when the vehicle was started.

The local repair shop diagnosed a leaking passenger side rear shock. Two new Arnott rear shocks were installed, however this did not fix the problem. They are suggesting a problem with a solenoid.

Does anyone have any ideas or suggestions on how to proceed?

There is a process to reprogram the ASM to react correctly to the height detectors, (two per rear, one per front, maybe two if an early car), following suspension work.
