Hi All
I have a 1997 P38 4.6 HSE and i'm having problems with my EAS.
The main thing is that when i'm driving it the suspension is all over the place. It is blowing the rear airbags all the way up so it looks like a monster truck but the light on the dash is showing it's ok and a solid light (not flashing). Sometimes it only jacks up one side at the rear but today it was both.
When you put it in access mode you can see that the rear airbags are not right down and it takes a long time to set, then when you put it back to standard profile it also takes ages to set......it seems to set better if I get out of the car but it's still slow.
Sometimes it sits level when parked and then as you drive the rear goes up even though the dash light is showing it as set. When I put it in high profile it won't set at all most of the time.
I have a cable and a software disc and it's not showing any faults. I have tried depressurising the airbags and tank but it's still the same when it goes back up.
I have put new o rings in the valve block and done everything in the compressor as well.
I have tried a different second hand EAS ECU but that didn't help so I have now put its original back in.
Just checked and the suspension is still up but more level after sitting for about 3 hours but it will do it again when I drive.
Are there any relays or switches that could be causing this? I've seen something called a Delay Timer....what is this and what does it do?
Any suggestions/help would be very much appreciated.
Thanks
