Rear suspension 🙁

[jordon]

Hi to all, can anyone help me my x5 has a rear suspension problem I replaced the o,s air bag, had suspension re callabrated but now the problem I have is one side will go very high and and compresser will still run, the side side going high is the same side as the air bag has been replaced, any help would be very great full

This seems to indicate an issue either with one of the height sensors, or much more likely the control valve.

First thing I would do is visually inspect the height sensors to make sure the linkages are intact and undamaged. Next thing I might check, since he bags were serviced, that the red and blue lines weren't inadvertently switched at the control valve.

Finally, I would plug into the vehicle and check the analog values for the height sensors, and scan for codes related to the system.

Yes that was my thought too. Check that BOTH R and L air lines are hooked up correctly and check level sensors as well. I ended up having a broken link on one of my level sensors on my 02 E53. I repaired the plastic link with fast set epoxy. It has lasted 2.5 years.

Thanks so much I had a feeling they had piped the bags up the wrong way, am I right in thinking n, s airbag (red air pipe) is port one from solanoid valve
