air suspension fault and light fault

[Porsche1]

this fault come on, car drives the same the best I can tell, shut car off, start and it goes away but it does come back on after 10-12 minutes. it says driveble but stay below 35mph, how important is that? I can't drive 35mph until I get it to the shop.

thanks

I think I would in MMI raise the suspension and drive around for a bit, then lower it back to regular level and see if it resets the sensor. I would also with car running get a tape measure and on a level surface check all four corners raised and lowered.
