Rear suspension problem- back of the car is lower than normal. hello; I have an X5 4.4i 2005, the back of the car is lower that normal and the dashboard display saying rear suspension not adjusted. history: 3-4 weeks ago I drove the car to work as normal, leaving in the afternoon i noticed that the back one side is lower than the other, but after starting it up it adjusted it self. now the back suspension both sides are low and one of them is lower than the other still. I read some comments saying i need to re bot the computer system with buttons available to me on the dashboard But my car model does not have the said buttons. please advise. Thank you Andrew
If it's an x5, you are probably, and when I say probably, I mean, change both of them and buy a spare. More than likely, your vehicle has self-leveling rear-axle suspension. This means that your vehicle has air bags in place of the rear shock absorbers. There is an air pump under the rear cargo mat. It regulates compressed air between what are basically, two cylindrical air bags places where a gas strut would normally be. These air bags (pneumatic springs) rot away from folding under the weight of the car and leak. The car pumps and pumps, but the ride height doesn't change, so it tell you that it isn't work and stops trying. I'd recommend changing both of them at the same time and clearing the module's fault codes with a GT1. My company charges 2 hours to change one. So I would say 3 hours elsewhere. Pretty straightforward to do, if you know what you're doing. You can find it in the BMW catalog under: REAR AXLE SELF-LEVELLING SUSPENSION LEVELL.DEVICE, AIR SPRING AND CTRL UNIT
