Good day!

I had the same thing happen after I got my 2 axle air ride home! It was giving a display, but not airing up. Later I found the pump disconnected and noticed the pump has been replaced. I had converted it over to coils since but after hooking up my computer and talking to EHC module, I could control the system. I must have changed the system configuration somehow to get it to respond... I have a bad height sensation on the rear, but it's at the correct ride height due to the coils... I turned off my error message in the LCM, so I'm not sure if the system is still faulted with the coils in... I used INPA to control the air pump and work all the valves. They all responded perfectly. I might be converting it back over to air ride today...

Do you have a laptop and BMW tools 2.12 installed?

Good luck! Let us know what your do to fix it!

Cheers!
