P38A EAS question

If you did a "Read All" those figures look OK to me

Yeah, did 'read all'.

If there is a dodgy height sensor would this always show a fault code?
Is there anyone willing to bench test the valve block?
Thanks

A dodgy height sensor will not always show a fault code. Erratic operation may show up on live data.
If the car doesn't drop overnight with the EAS relay removed or the rear hatch ajar, I would say your valve block is OK. If you have a specific worry about it, Replacing the O rings is not a difficult job.

So it does the Normal & High modes ok ? Is the problem still pump running all the time ?? If yes, then it's either worn out, or there's a leak preventing it reaching full pressure ?

For bench testing the valve block, I have the kit, but probably too far from you.

Thanks the offer, might end up posting it to you!
Yeah, pump still running all the time. I'm going to try get some live data this weekend. Thanks everyone for your help, not giving up yet!

Get a pressure gauge, and connect it directly to the pump output. When pump runs it should rapidly go up to >>150psi. If not pump isn't producing enough air.
