Hi Folks, A conundrum for you. Having problems with the near side rear air suspension; symptoms: only effects the nearside; offside is fine. drops periodically (becoming more often) when car is parked up and engine is switched off will normally drop within a minute or two and you can hear a release of air from the back of the car seems to be susceptible when the temperature drops a little (but TBH that could just be coincidence) when I start the car up, it levels out and all looks fine recently when driving, I've gone through a few bumps and smaller pot holes and it feels like its dropped (feels like its on its bump stops - again, only on the one side); after 20s or so it sets itself level again and I can continue. Originally when it started happening, I took it to the dealers. They ran through their standard tests and couldn't find any problems (not sure the suspension dropped whilst there); they checked the air bags - no leaks. Getting worse (again, only on the one side) so dropped it down to my local garage - it didn't drop whilst there; they lifted it, checked for leaks... nothing. No error/fault codes reported either. Their thinking: can't find any leaks - not the air "bags" likely the compressor, but there's no fault codes indicating there's any real problem there. Again, it only happens on the one side. If it was a compressor side problem I'd have expected it to effect both sides... Any ideas? Thanks!
Hi, I am currently in Scotland with my E61 (2007 LCI facelift) & have had the above fault come up. This is the first time i have had it & a problem with the suspension. After doing some research on the 'net i have done the following things: -Checked fuses. All ok. No issues. -Checked the ride height sensors: NS: If i move the the arm up or down i get no click from the relay, or the compressor kicking in. The air bag is also soft (with the car jacked up) , however this side is sat higher. OS: If i move the arm up or down i can hear the relay click, but again no compressor kicking in. The air bag on this side has pressure in it when the car is jacked up. (I am unable to reach the airbags when the car is level on the ground to check if they have pressure or not) I am making an assumption that the 1 relay controls both sides here, and it is not independently controlled. Is this correct? Is there a way i can test the relay/the inputs on the car by shorting across the contact terminals to make the compressor kick in? What else is there in the system that i can check that may be preventing the compressor from kicking in? I have limited tools with me, so can only diagnose via testing parts on the car and the way they should respond to inputs. On another note can anyone recommend a good BMW Indi near/around Motherwell. Thanks in advance.
