BMW e60 e61 rear air suspension airbag or air spring replacement
This is how i did it. You are supposed to discharge the air supply by loosening a union on the pump. I couldn't be bothered and so i didnt.
You should swap the units in pairs. I have also learnt that you shouldnt pump up the suspension from fully compressed. Not sure why as when the old airbag failed and had a slow leak, the car pumped up from fully discharged multiple times with no apparent issues?
Anyway hopefully this video helps someone doing the same job.
