2002 745li self leveling suspension lean fixed
The left rear of the car was sitting about an inch lower than the right rear. No error codes. Didn't bother me too much as the lean was not too bad. Had to replace the left bushing (ball joint) as it was worn. (unrelated issue) Came back from the workshop, and the lean was now more than 2 inches. Researched, found nothing short of re-calibrating. Here is what worked for me, not saying this is the solution for ALL lean issues, but worth a try as it costs NADA!!!!.
Jacked up the left rear, removed wheel. Just to the inside of the hub is the self leveling sensor, which looks like a little black box, with two plastic links that connect to the axle carrier. Now, BMW in their infinite wisdom, mounted this sensor on a metal bracket that can be bent by a two year old girl. The bracket was obviously bent some more while replacing the bushing. Here's what to do.
If the side you're working on is LOWER, bend the bracket+sensor LOWER by hand. Do not use a hammer, unless you are a 1 year old girl. Anyone bigger can gently bend it down. Now, put your wheel back, switch off your noisy compressor and the crappy music, lower the car and listen to the sweet sound of the compressor pumping air, and look at the clearance between the wheel well and the wheel to see it lift up!!!! Adjust as required if too low or high. Didn't even take the wheel off for adjustment. Open a beer and celebrate. You just saved $$$$$$. Good luck. (should work for 5 series with self leveling suspension methinks)
