Self levelling suspension

[mkelly21]

I have 30d 2009 which has 7 seats.

We often park the car on the kerb outide our house and you can see and hear the car lower & raise. Recently after the car was parked on the kerb I moved it to our drive and when I got in the car in the morning the car was still low on one side but as soon as I started engine it raised (and stayed raised for days)

Over the past few days I’ve parked the car on the same kerb and noticed it’s not lowering. There are no error messages being reported.

The question I have is under what criteria does the self levelling suspension work? Is it based on weight in the car? Angle of kerb?

I checked in the manual pg 86 and just talks about error codes.

Thanks in advance.
