Not sure on the exact cost, my awesome service advisor got it covered under waranty as a good will repair. The total billed to BMW NA including front brake replacement was a tad under $2,000... I would guess about $800 or so?

Been reading all posts related to this suspension fault issue but can't seem to find one similar to mine.

GT1 reading says that the voltage reading on my right rear is something like 0.64 while the one on the left is 4.60.

The mechs switched sensors and still the one on the right has a low voltage and sometimes 0 reading.

Any ideas?

My 2001 X5 is self leveling in the rear only,which i just found out myself yesterday by my mechanic.:D

The wiring/pins condition/continuity/ohms and output voltage from the module should be checked. (but not all mechanics are at home with tracking down electrical problems)

Hi Weasel! So should I assume that there is nothing wrong with the sensor? I was allowed to watch them work on it in the service area and they were switching sensors from right to left and vice versa. Problem always appears to be on the right (low voltage reading).

They were working overtime to try and trace the problem. I'll find out in the morning.

Yeah, sounds like the sensor is good. They need to check the supply voltage to the sensor, it should be 5v.

Weasel, turns out to be an LCM issue. Had it repaired. No more fault warning. I didn't quite understand the mech's explanation on how it caused the fault.

That means you only have to pay for compressor and rear shocks if stuff goes bad.....:confused:

When Does the compressor kick in? Is it by weight?

its the rear of the car level?
