Well I guess the solenoid clean & check didn't do it... it faulted twice in a day. I fitted the Driver Paul kindly sent me on Monday afternoon and drove the RR last night and most of today with lots of engine stop/starts and fingers crossed it seems to be OK now. I have to go to Brisbane in it tomorrow so we will see how she behaves but feeling quietly confident. I hope that last comment doesn't put a curse on it.... Phil
Well unfortunately the replacement driver hasn't fixed it. I have had the same fault show up everyday since Thursday "inlet valve stuck open".. I think it is just coincidence but the new driver was fine for three days it was only when I had new front tyres fitted that it faulted while in the workshop and has continued to fault everyday since. The RR was jacked under the axle for tyre change and I would have thought that any fault relating to this would have shown as a sensor fault not an inlet valve fault. I am now thinking of replacing the inlet valve solenoid. Any other suggestions would be appreciated it is now starting to bug me to the point where I am thinking of re calibrating the high mode to a level for general on road driving and leaving it in fault mode. Cheers Phil
I'd be looking real hard at those front wheel sensors after the tyre fitter had a play there even though the fault is listed as an inlet valve. It may be coincidence and you do have an in inlet valve fault but it's funny how often I hear of EAS faults after an EAS fitted Rangie has been jacked up by non Landie people.
Perhaps a simultaneous front double wheel sensor problem was caused by the tyre fitter and the car was overwhelmed by the two simultaneous faults and in its confusion logged it as a valve error????????? :confused:
Thanks, I will take a another look at the front sensors. The only thing that steers me away from them is that after three months of ownership the only EAS fault to show up is "inlet valve stuck open" and this has come up about 20 times during this period before and after airbag replacement, valve block overhaul & EAS driver replacement. Any tips on changing front sensors. I thought I would try swapping them side to side first as mentioned elsewhere.
was it a used driver unit that was fitted? if it was then it may also be faulty with the same problem.
Yes, it is a S/H driver unit that was reported to be working OK so I suppose it is possible but what are the chances of showing exactly the same fault. Would I be right in assuming the problem has to be somewhere between the valve block & driver unit to show this recurring fault or could it also be after the driver unit ie in the loom or under the seat.
it is normally a heat related circuit board fault inside the valve block driver unit. some times the fault is so bad it can be seen through the soft insulation material as a dark patch or even a burnt away hole.
Thanks Rupert, I will check it out. Can they be repaired by a competent electronics guy I have a friend that designs/builds pcb's? Although I like to save money at every opportunity I am more than happy to buy a new driver if it is a fix but there seems to be no way to confirm that it will cure the fault!!! I also saw the following on another site:Inlet Valve stuck open No Alternatives. Set when system is unable to make more than one sensor meet it's target value. Could this lead me to a faulty height sensors?
yes some of the driver faults could be repaired but removing the board from the case is tricky. thinners disolves the rubber but i have never tried to reuse a board after this as the insulation is always too damaged.
faulty height sensors can also cause the inlet valve stuck open fault,but it is rare. i have seen this when only one new height sensor is fitted and the system is not calibrated. the vehicle may have an intermittent lean to one side and the live readings show a difference of about 12 between the two height sensors.
Well I have just realised that I have been ignoring another fault "vehicle has moved" while concentrating on the "inlet valve stuck open" It appears that whenever the soft fault occurs both the above faults are logged. Does this help narrow down whats causing the problem or make it harder to locate. Also I recalibrated using spacers on the bump stops and the settings for the front L & R differed by 5 to 7 points would this cause an issue with the ECU
