Okay, just getting back to trying to get this sorted. My garage have done extensive leak testing but have found nothing, so looks like it will be trial end error part replacement if I want to get this fixed.

I'm going to do some tests over the next few weeks by leaving the car in different settings including jacking mode. In the meantime can anyone help me understand these observations and if they help pinpointing a faulty component:

Car is left for several days and the rear (both sides) drops right down (67cm from ground to top of wheelarch). I open the driver's door and I hear a hissing sound and the rear of the car rises to 74 cm. I start the engine and the car rises by about another 1 cm.

Despite the leak it seems that something is staying pressurised. Thanks for any help on this!
