EAS again!

I have new pump, new valve block and no detectable leaks. Suspension lifts OK but on standing drops on front O/S. Dealer reports no adverse faults on diagnostic check. Only item left is control block under valve block - anyone with experience of problem here?

you need to spend a lot more time on the bellows that drops and the air line from it at the top and at any joints that may be in the line back to the connection on the valve block with soapy water, cause if the valve block is new there is no other place to cause this.
