I have a w220 with airmatic suspension.
For almost a year now the pump as run frequently and is audible whilst driving.
My 1st test was the obvious check for leaks but I was confident that wasn't going to be a problem.
My reason is there have been occasions when the vehicle has been parked up for 3 to 4 weeks unused and during those times I measured the wheel arch to ground from 1st parked to return.
There was no drop on any of the 4 wheels.
Anyway, recently the raise function has shown that somethings not quite right.
The vehicle raising light in the cluster stays on.
And although she does raise, it doesnt seem to be as high as I remember in the past.
I think its safe to assume that the pump is weak, and prevention is better than cure so have ordered a wabco unit from e bay for £218 (not a bad price)
Can you guys give any advice on pro's and cons for replacement.
Apart from reports of seized mounting bolts, it looks like a atraight forward swap out for a competent DIY mech.
Thanks in advance for any advice, Happy motoring fellas.
