VDDM height sensors - damachone - 05-11-2026
Hi everyone
I recently replaced the lower link on the rear right suspension height sensor on my 2017 S90.
I don't have air suspension, so this is only used for headlamp levelling.
I still get a DTC saying the value is out of range, and when I monitor the VDDM DIDs for front and rear height, the readings are very different and move in opposite directions when the vehicle height changes.
I was really hoping someone could check this on an S90 and tell me what "normal" looks like!
When I replaced the lower link, the "elbow" could go in two orientations, either towards the centre or outside of the vehicle and I am wondering if I picked the wrong one...
Any suggestions much appreciated!
