Thread: P38 EAS fault

All the EAS info you need is here.
Air Suspension Faults, Diagnosis and Repair


The compressor gets very hot under normal conditions.
You need to reset the EAS system before it will work

Get yourself an EAS cable and software from Hard Range or e-bay

Either buy or make up q self-rescue system to manually inflate each bag.

It's a T -piece with the arms between the valve block and the 4 hoses from each corner. The "vertical" or base of the T has a tyre valve fitted. - if the EAS - ECU has a hissy fit (no pun intended) then you can fill each bag with a compressor or servo hose.

Best to also have a tap between the T and the block, just in case your problem is a stuffed or leaky pneumatic valve.

The beauty of this more $$ 'isolator/rescue is that you can remove the valve block and repair at your leisure, - still driving the car.

Yes a nanocom will erase the logged fault, but it won't fix the problem with the pump. It may have overheated, could be a faulty overheat switch too - those links are really good to follow!

To my knowlege, there's no nanocom dealer is oz. Paul at hardrange isn't stocking them. It's about $550 mailed to your door from Cyprus. And yes, it will read alarm codes, etc. too.

Have you tried swapping the pump relay?

Double what James posted too - worth their weight in bundy!

Thanks guy's,I had the worst drive ever down to Wyong to get faults read & cleared(I so much missed my air springs)& the gent @ English Auto did a great job.We reset the EAS & HEVAC,as it turned out I have small leaks in my rear bags & she dropped out of range onto the bumpstops overnight & compressor/EAS computer would not start.
Reset everything & up she came,no more problems for now.
We think the combination of air leak&heavy towing put compressor out on over temp & would not pump up.
As soon as Paul opens up his shop again I will be getting a by-pass kit to save me from the worst drive ever again!!!
Will also look @ a Nanocom Evo,these things look the good's & if it only saves you once a year it will pay for itself in 5 year's.

Thanks Steve

until you get a new bag it may be worth putting it on the heigh setting overnight, it might not leak at that setting, and save you from another fault.

Yes, worked for me when I first bought mine.. both rears leaked a tiny bit on 'normal' height.


Whilst the Nanocom is the more versatile gizmo, check out BBS here:-

- I've got the EAS Kicker, and it lives in the glove box at all times. - Quick and easy to connect and read/clear faults. It can also read and re-set individual heights, though I have'nt bothered to fiddle. Around $200. Add the Self-Rescue System and you've spent about $400. - Then buy two rear bags.

If the rears are leaky, chances are the fronts are not far behind (!) and the compressor is heading for an overhaul along with the valves further down the track...

It may be easier/cheaper to go 'springs' and use "Polyair" inserts in the rears for manual load-levelling.

Best to drive one that's been converted to the Dark Side before you spend too much.

Sound's good ,will buy half a nanocom with son as he is the proud owner of a 2000 model p38 so we will both get the most out of it.

New rear bags coming & a bi-pass inflation system is also on it's way.

Ps I love the air suspention it gives a great ride & self levelling is brillant when towing.

Thank's Steve

X2 on EAS kicker and EAS bypass kit as most valuable "get out of jail" tools. Although splitting the evo sounds the way to go given 2 in the family.
