MY E class keeps droping at n s rear

[dave 145]

HI can any one help i have a 2004 e class estate with full airmatic ,which has had two new rear shocks & a new pump but when parked for more than two hours the N S rear drops , regards

As you have eliminated the struts and pump, I would geuss a leak in the pipe from the pump to the n/s/r strut or a leaking/faulty valve block.?

As a quick check spray the pipes and unions with soapy water and look for bubbles or listen for hissing noise maybe.

when you say shockers replaced the dampers and the air strut are speperate on a 211 estate iirc?

As Toger13 says, the estate's have a seperate air tank with is seperate to the shock. They are a real pain to fit propley as you have to drop down the sub-frame. I i have see poeple cut the connecting pipe and re-connect it to make to job easier.

If that has been fitted right, then it may have a leak in the vacunm pipe under the rear seat
