In Reply to: Repairing self leveling, rather than removing it? posted by JohnG on September 18, 2001 at 12:51:37:
I have noticed that with a full load (4 passengers + luggage) our 91 535i does sag a bit in the rear, so I assume an M5 would do the same without self leveling.
Would it be advantageous to maintain the functionality of the self leveling if you wanted to maximize handling with a full load at high speeds?
Is there any flaw with the self leveling system other than the fact that it starts to leak after 10 years/100k miles?
John, If you can keep it. The main problem with the system is failure of the accumlators. These are what hold residual pressure in the system and keep the compliance in the suspension. When these go bad, additional pressure is required by the pump to keep the car level and the system overeacts. Leaks in the shocks and pump then start to happen. I removed the system on my e 28 m5 and I miss having it.
