My car was parked on a slight incline. I jumped in to move it real quick, cranked it up, put in reverse real quick, and hit the gas, well all of a sudden I hear an error beep and see an error message appear that said “Extreme level Wait until ready for operation Engine must run”. I couldn’t find anything about that specific error message in the owner’s manual. I went ahead and drove the car home. The message went away as I drove, but then reappeared if I stopped on any sort of incline. I’m thinking it has something to do with the air suspension because I pressed the sport mode button to change the chassis and it gave a message saying something to the effect of it not being available right now. Also, after I put it in park and turn it off the suspension usually lowers the car a little and it’s not doing that now. I just bought the car a week and a half ago and I’m afraid I’ve f**ked it up! Here are my questions:
1. Is it safe to drive?
2. Have I totally screwed it up?
3. Is this gonna cost an arm and a leg to fix? I bought Endurance Warranty but it doesn’t kick in until 1000 miles.
Help!!

 

You need put your car on flat ground and control height values
You need to control with a piwis the real problem. I thing it's problem height sensor

 

Thanks for the info!
This is my first post. You can probably tell I’m pretty green. I don’t have a Porsche dealer nearby but I have a friend of a friend that’s a super mechanic at the BMW dealer. Think I should try taking it there or an independent? I obviously don’t have PIWIS II myself, don’t know if BMW would?

 

Without piwis iy's difficult make diag.
You can try to disconnect battery 30s and reconnect it.

 

Decided to take it to independent shop. Now this is wild…was driving and error message went away. Got there and tried my different chassis settings and the air suspension worked!! I could see the car raise and lower between settings, so I left. Couldn’t explain a problem to them that wasn’t there! Got home and pulled up to my driveway and the error message came back on and air suspension is not working properly again, car is sitting low, didn’t adjust when I cut it off. ???
