Hi all

yesterday, on opening my rear passenger door, all 4 corners went down to access height. On entering and start the engine, a suspension fault was on screen. I lifted the car into off-road height, then normal, then access and back to normal. Been a couple of runs now with now issues, but still have the fault showing each time on start up. My code reader is out on loan, but will get it back today, but wondered if any others have had a similar experience and if this is a common fault?

looking to spray all accessible areas with soapy water later today, and have ordered a new o ring kit for the valve block. Any other suggestions?
cheers
