Hi there,
I know there are lots of posts about this but I have read many of them and I am not sure if my issue is the same........so here goes.
I have a Toyota Landcruiser Prado GRJ 120R 4.0 V6 A/T Grande with air suspension.
Recently the suspension drops to the bump stops and for a while won't pump up again (2 days) then at some random point it will work again. I have found that if I pump it up high before everyone gets in, and also when I park up it is fine, dropping to normal height automatically while driving - but if I forget to pump it up once it gets lower (2 passengers in rear) it won't pump up and drops slowly down to the bump stops. Last night I tried jacking the car up (on the frame, not axle) and once I got it to nearly full height the compressor worked fine and pumped it up. The only other thing I've noticed is the 'turn off height adjustment butoon' (shows yellow shock absorber signal on dash) goes off once I start driving if I turn it on while stationary - I thought it should stay on permanently - otherwise it is a fabulous car. It is almost as if once it gets too low the unit has no idea what height the vehicle is (the green sensor light shows - N (Middle)) and so it gives up and won't do anything.
p.s. If I pump it up high it stays high for a day or 2 easily and I can't hear any leaks from the bags.
Do you have any ideas please?
Thanks. Bob
