P38A Eas issue

James Rogers · Dec 22, 2019

I've read a few and I think maybe height sensor issue but would like your advice.
Drove somewhere yesterday, all fine. Then again today for 6 miles or so, all fine. Then I didn't look at suspension but noticed that about 5/6 more miles the suspension was on wade mode and normal level was flashing. Wouldn't set. Turned off and on and still nothing. Suspension on high I thought I'd Coast it home. Half way it came up with eas fault with lights flashing. By the time I was home the front was down and the rear right up. Since then I've lowered the suspension, still showing fault. Checked all relevant fuses, all fine. What's the problem?? I have no diagnostics.

You need diagnostics. This could be corrosion in the white connectors at the foot of the A post behind the trim, the driver pack, connectors in the EAS box or many other things.
If you have a windows lap top the EAS diagnostics can be downloaded free, then you just need the cable (which I can supply) and maybe a USB to serial adaptor.
There is nothing you can do without diagnostics.

That's what I thought. I have a local dealer I use. Can they run the diagnostics?

it would be easier to buy one of Datateks leads and software. It will save you a lot of time and money.
Private message him and he will sort you out ( with a kit that is)

Worth every penny if you have a p38

Maybe, maybe not, the P38 is not OBD compliant and it will cost you more than getting the diagnostics.

Unless you want to be inundated with SPAM, remove your email address. I'll send you a private message.

Could be a few things. As above you need the diag. Also, while you are waiting, read through Wammers How To in the Technical Section.

Connectors behind a-post might cause rise to wade height. Failure to get there with fronts down and rear in the air sounds like knackered compressor from feeding a leak. Testing compressor in How To. For leaks I put on wading height, pull the delay timer under the passenger seat then walk away and see what drops in the following days.

Where is the delay timer? Is it a relay?

It is a tall black relay under the passenger seat.
