"self levelling suspension inactive"

[troja]

Last night on the motorway the warning code "self levelling suspension inactive" came up on the dashboard, with the associated warning "ding". The dash warning was flashing and the ding sounding every 20 or seconds. I was moving fast in the outside lane at the time and suspected slowing down might be a good idea, although not an option at that precise moment. I pulled off the motorway at the next junction with dash still flashing and dinging, stopped and switched off the engine. The display then went to "system failure" amid multiple "dings" and then "reloading" or "rebooting" (I cannot remember), before returning to normal.
Its been fine today.
Anyone had any similar experiences?
