From last few weeks the suspension is going into 'extended height' automatically. I will leave the rover for day or two in the garage and it the top light will blink and the height will go to the 'extended height' level and will stay there until i go to the highway and it will come back to the normal level. Today i was driving in the town and it went to the extended height level and the top light started blinking for a while. I stopped and manually lower it the normal height. Any idea what is causing this?
Thanks in advance.

Well it is likely to be electrical and could be the driver module/box (on the side of the valve block) starting to show signs that it is failing.

I had a similar problem when my fuse box was shot and the compressor was running continuously.

hello,
it sounds like a faulty diaphragm valve, not allowing the pressure to get out when this is required.
that leads the height sensors to report maintaining same height, ecu thinks there is a physical obstacle under the car and sends it to extended height.
it could be a clogged up exhaust silencer (from EAS) as well (very cheap)
I would try disconnecting the air line from the dryer (this bypasses the diaphragm valve & exhaust), if the car behaves normal, then it was the d. valve or silencer.
cheers, korkut

Hi,

I have almost the same problem... but in my case the problem that I have is, if the car run (engine running) the heights are little more "up" that it should (normal and high profile, and access)... if I manually lock him in the highway profile,f.e., he runs with the heights +- of normal position, but after I switch the engine off he calibrate him self to the correct heights???

Like Rich says, it seems a drive box failure...but Kork´s make me "thinking" about... because i think my RR is a little lazy going down...and also I have the dancing in the lights....the compressor kicks several times... and also seems that the front is little more up...

wi_ranger, did you note if the car raise itself in the night?

Before buying a new drive, try to rebuilt your Valve Block...

I have the same problem; seems related to being left for a few days and maybe low temperatures. I will try suggestions as above but interested in anyones fixes.

Isn't this compensation for your weight, so that when you get off the car the side that you were on goes slightly higher? In other words, it's all normal?

I didn't get time to do anything and it went into ' EAS Fault' ran the software and clear the fault ( too high pressure). Any ideas what it means?
Thanks again.

Had similar problem with going into Extended Height for no reason on it's own. If I stopped car selected Standard Ride Height all was well again for a day, week or whatever. Would also go into Fault Mode sometimes and Lock Ride in Standard Height with all Orange Lights in switch on continually.
Read Fault codes and that said something about Pressure Switch Stuck but can't remember exactly what, cleared fault and it was o.k again till the next time.

Based on Advice from Rich and Dennis Fitted new Drive Box and has been perfect ever since.
(Now proably tempting fate).

Cheers
