4.8is Air Suspension Inactive issues
 

HI

Hope someone is able to offer some assistance.

I have been to BMW 3 times with this problem. The first 2 times they diagnosed it and said no problems found and reset it. Both times about 3 weeks later it came up again after being parked on an incline for a couple of hours.

The third time it was at BMW they said the same thing so faults found but kept on looking and eventually they came back and said the EHC2 module and the air supply module need to be replaced. As soon as I left the dealership I noticed that the LED's on the adjustment rocker were out. This was not like this the first 2 times I was there.

So I thought maybe they deactivated something and when the module is replaced it will come back to life. Today I replaced the module and took it to a local indy who coded the new module to the car. Still the same problem LED's are still out and still have the Suspension Inactive message.

I did not replace the air supply unit as it had worked fine both times they reset the it. So I am at my whits end now not knowing what they did at BMW.

I have checked the fuses in the trunk and also the air supply fuses in the glove compartment, all not blown.

Am I missing another fuse somewhere? Help on this issue would be greatly appreciated.
Thanks

did you check the fuses.
