i am having a problem where the front suspension sometimes lowers all the way down (so the tires are almost touching the wheelbase)...when i get in, i have to give it a few minutes to raise up before driving it - has anyone ever had this problem? any idea what needs to be done to fix it? feels like it will cost me alot...
What are the ride height indicators showing when you first switch on with the suspension dropped?
I'm wondering whether one or both of the front sensors has stuck in a high position, and the car is trying to correct it. However if that's the case, the car won't pump back up properly.
If the indicators show low, then that isn't it, so it's likely to be pneumatic - possibly leaking valves, pipes, or suspension struts.
I'm a bit puzzled why both sides should drop though - I would have thought a fault is more likely to affect one side, unless it is a general air leak, in which case the back is likely to be affected as well.
I would check visually on the sensors (clearly visible with the wheel off), listen for hissing when the car is parked (this can be normal, as the suspension remains active), get a look at the diagnostics. Interprpting the diagnostics may not be easy in this area though.
