I have a similar experience and I'm stunned that it's so hard to find a working solution. My E55 was hit dead on the driver side rear rim by someone. Not a single scratch or anything to the body or frame. The part that needed to be replaced was the rim and the part where the axial is going trough.

Since then the ride is hard and stiff like Sport 2 mode in any modes (Comfort, Sport 1/2, raised).

I also noticed that both rear tires literally sink into the wheel house after it is parked for 3-4 days.

Any ideas where to start before paying stealer ships to do their trial and error work?

I checked the error memory with SD and no errors to start with.

Problem solved- to quite an extent

My ride has become quite OK- turns out it was my Airmatic valve block which was faulty which was causing the car to lean. (and which killed the cushioning effect of the air springs)

Very interestingly, it passed all leakage tests through Star Diagnostics; I found the problem when i was manually trying to level the car out.

The way I noticed the problem was this- I tried inflating and deflating each side independently, and whenever i was inflating any side, the front right level would also raise a bit, and whenever I deflated any side, the front right level would fall quite fast.

On checking through SD, no leakage was found as the leak was not out into the atmosphere but within the system and the tests don't seem to check for this.

Anyway, as of now the lower arm bushes need to be changed which i will be doing in mid September. I will post pics of the same once its done. (The ride is comfortable but I'm getting a characteristic clanking sound of broken bushes)

Part numbers on order:

Front suspension bush rebuild:
A 164 333 03 14 - Control arm bush (1 per side)
A 164 333 04 14 - Control arm bush (1 per side)
A 164 330 07 43 - Control arm bush and aluminium housing (1 unit)
A 164 330 08 43 - Control arm bush and aluminium housing (1 Unit)

Rear suspension bush rebuild:
A 164 352 01 65 - Control arm bush (2 per side)
A 164 326 06 81 - Control arm bush (1 per side)

I have decided not to change the bushes on the upper control arms as I intend on replacing the control arms along with the bushes as an assembly shortly.

I did all the testing too. All 4 sides have the same pressure, the compressor test finished in 14 seconds out of max 40 seconds to go over 14 bar. The valves have the same electrical values when tested.

I have a feeling the the valve block has something on my car too or the T-splitter.

Internet in my phone is too slow to upload pictures of the wheels showing how low they were after 3 days and after 4 days.

Thank you, I have the same problem even with brand new airmatic struts. I will be posting later after I have my faulty ECU replaced.

What faults were stored before you replaced the control module?
