Always had occasional issues since converting back from springs about 3 years ago. Usual slow to go up, that's all. No dropping corners or such like. Could go many weeks without a problem. Not now...
Faults listed were front L/H & R/H height sensors plus an unknown, (think it was called something else).
I replaced the height sensors but this didn't improve matters. If I leave the car and it settles a bit, occasionally it will take ages to go to correct height, sometimes a few hundred yards, sometimes 10 miles!
If I clear all faults, all is good and ride height is achieved.
Decided to check pump the other day as the periods of, "playing up" are becoming more frequent. Start car, light flashes to achieve correct height but pump remains silent! Now when I clear unknown fault, pump fires up and problem solved.
I will add that I renewed all O rings and seals to valve block and pump when I brought the car back to EAS.
It seems to me that sometimes the pump isn't asked to switch on, any ideas.
Strangely today after the car had been sitting on level ground unused for two weeks, I started up and within about a minute it was at ride height. Later today, I reversed to hitch a trailer on a slope. Switched of ignition, got out the car and a clicking noise was heard, (valve block opening?) and the car settled down a few inches for no apparent reason!!! So annoying
I really need to solve this as it is ripping the joy out of driving this car...Help please.
