F11 Air Suspension
Hi All,
I had an air suspension issue on my 2016 F11 Tourer with the air bellows leaking. I changed them and had no further issues for 4 weeks (nearly to to the day), when they dropped again whilst driving. I pulled over and the compressor ran for them to pump up again. A couple of days later the same happened again but they would not pump up. After having a look and checking for any other leaks, none were found but bellows pumped up again. Used the car for a further a week and the same has happened again?? I have also changed the relay. Does anybody have any idea to what the issue could be? Thanks |

Check the relase valve in compressor.
It may be stuck from time to time since it still can pump the bellows. I had different issue when the release valve was stuck in closed position and it wouldn't pump down. Change it and everythin ok for last 6 months. |

No need for that expensive job.
There are 2 valves I changed (relese and split valve wich directs the air to two belows), moisture beads that can get soaked with moisture and block the compressor and relay wich you've already changed. I my opinion it is release valve wich is coroded and it got stucked. The problem is BMW does not sell this part separate, only with complete compressor unit. But Ali express have them and they are inexpensive. Also check if there are any leaks in air hoses, but is you said that both sides colapsed it's valve issue. |

Cheers, we’ve been away since Sunday and had no issues until coming home today and it’s happened again. Luckily I had ordered the part and should be here today also, as soon as it comes I’ll be changing it. My only fear is overworking the compressor and will need a new one anyway.

The valve finally come and I’ve changed it, I took the opportunity to check for moisture in the compressor. The desiccant was soaking wet so I dried it all out. I also changed the control valve whilst I was there. So far so good, I’m also convinced the bellows are now more solid and the ride is better (this might be in my head though). I’ll keep you posted if I have anymore problems.
Thanks a lot for your help! |
