Someone Help!!!!!!!

Here's the run down.

Just replaced the EAS Compressor on my RRS after the old one blew. Before this everything was working fine. The relay was also replaced on recommendation.

I got home and parked the car on the drive as usual (Standard height setting). When I got up to go to work in the morning the right hand side of the vehicle had raised up to OFF ROAD HEIGHT and the left side had stayed at STANDARD. I unlocked the car, it gave out a hiss and started levelling. I returned the car to the Dealer and they carried out a suspension calibration and sent me on my way. I returned home and parked the car on the driveway and woke up in the morning to find the Right hand side had raised itself again.

I've since parked the car at standard height and both individually and collectively pulled both the fuses and the relay out. The right hand side of the car still raises on its own. I also reached for the tape measure to check everything was level once the engine was running. At STANDARD and OFF ROAD settings the right hand side of the car is 25mm higher at both front and rear arches.

The only info I have on the compressor is that there were 2 part numbers listed. The one I had fitted was the newer part number that had superseded the old one.

Can anyone shed any light pleeeeease....??

Cheers....!!!!!!!!!

I didn't think it was possible for one side to raise on the rrs. Front axle and rear maybe but not n/s to o/s. Maybe I'm wrong.

Unfortunately felstmiester I can confirm that it is happening and really doing my head in. Every time I park up the right side raises and the left stays as set.

The only way to keep the car level when it is parked is to exercise the suspension a few times when i pull up therefore draining the air reservoir. The dealer is clueless and can only offer me 2 days of extensive and expensive fault diagnosis.

I'm hoping someone has come across this before..!!!!

If my mind serves me correctly the rrs has a split system between the front suspension and the rear. Meaning if there's a fault with say the near side rear sensor it will raise the two rear airbags as it obviously won't just raise one corner, same process if say the front off side sensor went, it would raise both fronts. Could it possibly be that there's nothing wrong at all with any of your sensors and that the compressor is not pumping up one side because there is some kind of fault with the airbags or lines going to them two airbags. Long shot I know but as mentioned above suspension gremlins on the rrs normally ends with the front jacked up or the back. Wich says to me you have a totally different problem.

Yep it's definitely a weird one...!!!

All 4 complete shocker units were changed about 4 months ago and were working fine until the compressor went. And indeed when I'm emptying the air tank, as I park up, it does use it's last breaths to pump the rear end up before it tries to raise the front. That would confirm how you describe the system operation. The spanner in the works is that the suspension seams to work fine on the road. It's just when I park up that the right hand side lifts on it's own. I also agree with your thoughts on the sensors. I'm thinking that when I remove the fuses and relay it removes power from the system and therefore any electrical inputs.

Firstly. And this may seem a stupid question. Is the suspension deffinatley pumping up on one side and not settling down on one side? Assuming it is raising then we can def say it's a fault.

When you had all the work done was the suspension calibrated? Now I'm not sure if this needs to be done on the rrs but I know on the p38's it was advisable when swapping any sensors or airbags.

Also. And I know this from experience is that the sensors are very temprimental when they're around water. Any kind of water ingress will play havoc with the range rover suspension. As soon as the rain came and mine was used the other week mine started messin about, raising up at the rear and like you say the only thing that cured it was to keep dropping and raising it to eventually set it right. This went on for a few days then righted itself on

The only thing that puzzles me with yours is the raising on one side only. If it was sensors only, then I could put money that it would raise front only or rear only, witch kinda makes you think maybe this calibration thing. Thinking about my other post above, surely it can't be a leaky pipe or airbags because it pumping them up regardless of you pulling fuses. Unless of cause the side that's raised is correct hight and the side that's not is .
