L322 Suspension goes up not down!

Hi all,

New to this site and have not long purchased my first RR 2003 V8 Vogue with a gas conversion. 4 days before going to Cornwall i had the suspension inactive message. Found a guy who cold look at it quickly and he replaced the compressor, set all the ride heights up and I payed up £850. I was in a rush so didn't test it, got it home and found that the suspension wouldn't go down to access level but would go up; to get the suspension down from its high setting I had to drive it until it dropped to standard height. If I hold the knob in the console in the down position it would start to drop, get most of the way down then just start to rise again. The mechanic has had it since last week in July and keeps saying hes too busy to look at it in depth but has changed the air suspension ECU and its still the same . Any ideas as to the problem as I'm thinking of getting it back and trying to sort it myself. (suspension went up and down OK prior to compressor failing). Thanks, Steve

Take it to someone that knows what they are doing, this guy clearly doesn't, he's just changing stuff in the vague hope it might fiX it. EAS ECU's are not a known failure item.
It sounds like he failed to do the ride height re-calibration correctly, something that did not need doing after a compressor change.
It's quite likely the compressor did not need changing either, many things can cause the "Suspension inactive" message including for example a low battery.

You have obviously been to a guy who doesn't know much to say the least.
My counsel
Invest in a Gap iidtool and read out the suspension errors.
Calibrate it properly. All you need is a tape measure and your phone as it works by Bluetooth. The picture shows a typical de calibrated situation.


Go in the test valves procedure. One might be sticking but doing it several times sorts it.
You may have to go for a bumpy ride and calibrate it again
BTW 850 quid for a compressor is more than here, including our outrageous import tax. To this day I have never seen a bad ECU but for case of serious flooding
