Having overhauled my 1999 EAS over two years I've had a problem free 6 months - EAS like new - didn't drop an inch ever.

The other day drove to work, no worries, came out in the evening to drive home and noticed the car was half way down all round . Got into it and the EAS light is flashing non stop, the compressor seems to be running but the car won't rise or do anything - up or down.

Took the compressor out this afternoon - a little noisy but I did replace the seal 6 months ago, and it does pump but I can block the airflow out the outlet very easily with the tip of my finger with no pressure. Normal? How hard should it blow - I am an amateur with no pressure gauge.

The exhaust air filter doesn't seem to be blowing air when sprayed i.e. no bubbles - even took it out an tried to see if air was blowing - couldn't feel anything.

Unplugged the airlines from the block - there was air in all 4 bags and the tank - a good blast.

Was going to take the block apart but then thought I would ask Dennis or anyone if they had any bright ideas before I go rebuilding the freakin' thing for the 4th time.

It won't pump up - everything is 6 months old and the problem started apparently immediately. Suggestions?

Anyone? Help!!!!!!!!

Do you any message eg EAS fault on the message centre.?
Best would be put a diagnostic reader and see if any fault codes are logged.
From your description it sounds like an electronic fault,best to try and prove/eliminate that before chasing leaks,valve blocks etc. :think:

Thanks John but how does one get readings from the EAS?
No there are no messages on the message centre. Just the switch middle light flashing and the bottom light solid.

Thanks

there's something wrong with the compressor, you should have good pressure at the outlet, you shouldn't be able to hold the air back with your finger. If the small oring on the discharge checkvalve in the compressor head leaks, it will wear out the seal incredibly quickly. Same with a failed diaphragm, since your compressor isn't working, you won't see anything at the exhaust muffler.

You can get software/cable or an EAS buddy to pull the codes at http://www.rswsolutions.com

Thanks Dennis - I must say I suspected the compressor was weak, it was making more noise than usual - do you recommend a rebuild or purchase new?

Do you sell the o ring discharge checkvalve in the compressor head as well in your compressor overhaul kit? I see you are out of stock on your website - when are you expecting stock? Any suggestions what I can do in the meantime - it's my only drive?

If I change the teflon ring, add a new cylinder and change the bearing what are the odds of the actual pump electric motor bushes will last any length of time? Can one repair those to ensure a whole rebuild?

Thanks so much for your help again (as usual!) !!!

I just had a reed valve break in half on the exhaust side on a fairly new compressor a week back, O ring within head should be replaced when doing a rebuild, Viton rings are the best as they are high heat rated.

Unless bent or broken, the reed valve will be ok, just clean it up. The factoryis moving, so they don't have stock right now... Hopefully sometime in the near future.

The brush end can be cleaned up and a new thermal switch installed if needed, I'm trying to find a good source for the brushes but they typically far outlast the seals.

As I am driving with no suspension is there any other source for the repair kit?
No sense in just replacing the teflon seal as it will wear quickly again without a new cylinder sleeve or bearing - do you still offer the rebuild on your website, Dennis - even if you are out of stock of the repair kit?

Thanks

Is your cylinder damaged? I missed that. I'm working on a better replacement cyl, I can do the rebuild service, I have a couple used cylinders I can swap in.

I don't know but if I'm replacing everything else I may as well replace the cylinder. If the new teflon ring wore out in 6 months then something is going on.
I certainly replaced the o ring in the compressor with the one which came in the kit, so maybe the issue lies with the cylinder although I did polish it when I had it out.
My issue is time - I'm have to drive every day on bump stops, so I feel it would be quicker for me to refurbish the cylinder if only you had the parts!
Can you send a refurbished compressor while I send you back the core to save time?

Thanks
Jacek

Thanks Dennis, however I have managed to borrow a vehicle so the immediate pressure is off.

Why if the compressor is pumping very slowly or not at all would the car lose height over several days?
I drove previously for several months without a compressor at all when you were resetting the EAS computer for me.
Is there an easy way of pumping up the vehicle without the compressor like form a compressor at a gas station?

Thanks,

Jacek

un-related issues. losing height is because of leaks. slow to rise is because of a worn out compressor. the compressor would have worn out faster because of the leaks, but may not be the only issue. I can rebuild your compressor as well, just mail it out to me.

Thanks Dennis. How long does a rebuild take approximately?

Aah, that makes a lot of sense!
So how do I order one from you?

shupack said:
If you send me yours I don't have to search junkyards for cores or chase people down to get their core returns.

Dennis - you are the superstar of EAS!

Thanks a million! I put the pump in, pumped up the reservoir and bingo, the P38 rose like a phoenix from the ashes!
What would we do without you?

Thank you so much, again!

( I wish you had such amazing replacements for all the P38 components!)
