X53 Level sensor under voltage

[Swirly]

Hi peeps, 2005 E53, I've had it to my mates garage, the supensension inactive warning is on the dash, he has had a play with the sensors, plugged it in and he has said one sensor is under voltage 2.5v, it will reset then take it for a test ride the suspension inactive comes back on, what are your thoughts, wiring problem? Suspension module? Is there a link to a wiring diagram for this year, I'm going to have a look it monday

Wiring diagrams can be found at newtis.info.

The website carries a copy of the same Technical Instructions used at a Dealership. Worth a look.
