Help…Adaptive Suspension Problem

[Proffo]

Hi,
I’m hoping someone may be able to help me. My F15 X5 developed an irritating vibration some time ago.m which coincides with the suspension feeling stiffer at the rear as if it’s stuck in sport mode.

I have performed a fault scan using ista+ whoever there are no codes stored for suspension.
I have however identified that both rear shocks do not appear to be communicating. When is check current to dampers both front dampers are present however neither of the rear dampers appear!

I’ve read a few posts on other models with EDC and have notes suggestions of recoding / reflashing the VDP and ACMS modules.

Has anyone on here experienced a similar problem or any any advice I’d be extremely grateful.

Thanks in advance. Jim
