OK, I'll be the first to ask a dumb EAS question.

Are you sitting comfortably?

Delay timer relay replaced with ordinary one years ago.

Problem ..... the car has always lost height at the front. The PO had fitted new bags (not Dunlops, the other kind that look like Arnotts) and when I got the car the front dropped after a few days standing.

I fitted Arnott Gen 3s about 3 years ago .... same problem.

Overhauled the valve block a year ago (existing one looked fine). .... same problem.

With cold weather here, the front now drops in half a day.

However, it always jumps to attention when starting up. The rear of the car stays up for weeks.

I've checked the pipe connections at the VB and bags but not recently.

Strange that both fronts drop like that?

Any comments welcome .. it can't be that hard to find, can it?

Fit Dunlops not some crap American aftermarket things.......

If is makes you feel any better, I have the same thing happen to mine, and I run the Dunlop air springs.

It's also weird as sometimes it doesn't do it if I park outside the house facing uphill, yet if I park facing downhill, the front will drop.

I saw a mention somewhere about it possibly be something to do with one of the NRV's inside the block itself, but I personally don't understand how as that would mean that both front valves would still have to be leaking back into the block.

It is a strange one - but if you find a solution... let me know!

Yes, unless both front bags or both front lines are leaking, it points to the valve block.

I might fix up another one from the several I've got lying around ....

Hmm, just had a thought. Should a question about EAS be in the electrickery section? It runs on 'lectric but it leaks so maybe it should be in the oily bits section......

I'm sure there's an admin on another forum who would make the decision and move it.

Well if we had a forum for "Leaky bits" then that would cover the whole vehicle and we'd never find anything.

And technically the EAS isn't oily - and if it is, then you have bigger problems! I guess electrickery is a good enough place since the first part of EAS is 'Electronic'

Mine does the same.
When engine running while hood is open I can hear the valves pst-pst-pst and the front drops half an inch, the same moment it corrects itself to normal height and after 20-30 seconds the pst-pst-pst starts again.
Might be a dead spot in a sensor, after all normal ride height is the most used position.
Over night it stays level (for at least 4 days), maybe because the Becm is in sleep mode.
Tony.

OK, time to own up.

Replaced two O rings and now holding up nicely ..... the O rings must have been bad from day 1.

Nicely :)
I'll add O rings to the list :/

Which two O rings? Might help somebody down the road.

The ones in the air bags themselves.

Thanks. Just realized I quoted the wrong post.
