P38A EAS question!

I have a 99 V8 SE, 99k miles. The issue I've had these past few days is the O/S/R seems to air out if left for a couple of hours. What is the most likely cause & the 1st thing to check?

Thanks guys

Leaking bag or duff EAS valves?
Someone who knows what they are talking about will be along in a minute I am sure.

Leaking airbag.

Seems everyone having eas problems all at same time don't forget data an wammers think I was the 1st one recently to bring it up again and mine not fixed yeti will have to get you two on a personal link I fink lol I'm not sure how much time I can spend on the old girl this wkend going to be a bit busy with jobs for the enemy but can't complain she's given me plenty of time to work on car and I'm away all wk will try to do a bit on it and keep you posted on my thread

Everybody who has air bags will have this problem at some point. They don’t have them at the same time, they have them all the time
Trust in what @Datatek & @wammers ask/suggest as trouble shooting a problem with this system. Follow it step at a time.
As I said a while ago I would have welcomed their help (before I knew of this forum) and struggled through myself.

My guess is 1 corner, look at the bag/line, or the hieght sensor then get into the box

Could the cold snap be having an effect on the presumably rubber airbags? Only noticed mine misbehaving since it got cold!

Don't fink the cold weather would cause it sounds like a leaking bag or pipe

Not really, although the rubber will be a tad harder which just might make it worse.

Everything has a service life. Bags as Keith says, but also the compressor. Without any leaks it will wear out through use and need servicing. With a leak it wears out a lot sooner. Specially if it and the system are not maintained. Why anyone needs to ask why their compressor has failed and why one corner drops defeats me. It is bloody obvious.

I ask because it's the 1st car I've owned with air suspension, having had it less than a month, I'm not used to its quirks & hissy fits, so I thought I would ask people that have!

Neil,
Chances are whoever did the bodges on the body, has neglected the EAS. Get the pump working first (eBay Refurb Kit), and then check Valve Block, Airlines & all four Bags for leaks with soapy water. Valve block is also easy to refurb, but use this kit from X8R which contains everything for the pump and block in one.

Also spend some time reading the EAS posts on here (especially Tech Archive) and learn how the system works. It's quite simple.

Ok sorry i may have been a bit harsh. But rebuilding the compressor without sorting what caused it to fail is not the way to go. Rebuild the compressor, sort the leak.

Hope to have a look after work today, as the o/s/r decided to drop while sat at traffic lights at 5am this morning, rubbing on the s#!t shield. I pressed the up button which sorted it out & was fine the rest of the way to work.....

You may have a leak on the solenoid valve for that corner if detritus from the drier has hardened it, but check the bag also.

Just got home, after doing it another 3 times on way home. When the suspension lowers, where does the air expel? Kept it on wade height to try keep the body off the wheels, parked it up & the o/s/r was hissing! Is this right???

Sounds like you have found your leak.
Squirty bottle with a few fairy’s in will confirm it easily.

No it's leaking. You need to check bag, connection to it and pipe. Under normal circumstances air vented from bags when suspension lowers is expelled from exhaust valve on valve block. The one with the white silencer screwed into it. Find leak seal it or renew bag or your compressor will be toast. Fit new bags in pairs.

What wheels have you got? They should never rub on the liners. Maybe the bumps stops are missing. If you find one leaking airspring, replace the lot as they will all be knackered.

Think the rears are well & truly f**ked.
Fronts look new & so does the compressor.

Yep I am sure we would all agree rears shot. 2 of in the post ASAP other wise you will be sending for a compressor as well.
