Suspension reset?

Hi, sorry to post another suspension post but I’ve been through various forums and can’t find my symptoms. 2004 4.4 petrol Vogue no alarms or fault codes but suspension just doesn’t change height. Selecting off road height displays the “off road height max 30mph” and the lamp flashes but nothing happens and no faults come up. Select normal height, off road lamp stops flashing BT there’s still no change in height. A couple of years ago I refurbed the compressor and I have a GAP tool. Last week I put it on axle stands deflated everything, took off the reservoir and main valve block and opened the main valve solenoid and rubber greased the O rings. I put it back together and started it up. There is pressure in the reservoir, when the compressor runs it fills up about 1psi per second, some times it stops around 60, sometimes 80 and is currently around 110 psi, which it maintains overnight. When reconnected it didn’t automatically fill the airbags to the correct height I raised it with the GAP tool suspension valve test option, I can hear the solenoids clicking and it raises a couple of mm at each click of the up arrow. front has come up but rear is still low. I re-enable suspension every time I come out of test mode and go to check live values. It,’s like its forgotten what the settings should be, as I missing a reset of some sort or does this point to an ecu or some other fault? Does anyone have any ideas? Thank you, John.

Well I tried disconnecting the battery for a couple of days, reconnected at 12:00 today as display screen isn’t working and it’s the only way to set the clock Smile started with the three amigos and air suspension inactive but full lock right and full lock left cleared all. Alas though reservoir pressure was still 102psi same as it was on Monday, suspension still showing the same symptoms. No warning lamps, no errors or faults, select either access or off road height and the corresponding light flashes but nothing happens. Can raise the front using GAP test valves function but not the rear. Think I’ll have a look at the ecu and connections, is mine in the passenger side dash beside the CD player or in the box in the engine bay? Cheers John.

Download the workshop manual from the WIKI, there is a work through for the EAS in there IIRC

It will also tell you where the ECU is... Pete

Reservoir pressure should be @ 180 psi...... .

Yes, it’s like it’s forgotten. Started it yesterday, compressor came on and at about 1psi/second came up to 130psi and stopped, no no faults no warning just stopped at 130.

I am going to point my finger at the compressor. A "refurb" will only last so long. I spent hours and hours chasing an AIR SUS problem, before giving up and buying a new compressor. Problem solved. You should be able to buy the bare compressor and wire it up into the turtle shell.

You could see if someone has a spare to try before buying ? .

Thanks Joe 90, problem sorted. Compressor replaced and all back to normal. Only about 2 1/2 yrs and less than 10k miles since the refurb , lot of brown dust on the foam by the cylinder of the old one. New one a doddle to fit, two year warranty though it is a Chinese cheapie, might live to regret that but we’ll see. Cheers, John.
