Air suspension on Grande

[ywork Member Find all posts View Profile Close ywork]

I have a question; my Prado seems to lower the back end if it’s been standing for some time. This would be when the vehicle is switched off. It did not do this before I had new springs fitted to the front end for a slight lift.
Then raises the back to normal, when you start the car. Is this normal should it be doing this all the time?
Cheers
Wayne

Hi ywork sounds to me like you have a airleak in the airbag system it could be hard to find if its a tiny leak if i was you i would get a squirt bottle with some detergent in it have the car running and spray the water around airbags and all related hosing etc if you have a leak you will see bubbles then i would raise the rear to high maybe it has a crack in the bag up under where the bag folds up this would more than likely cause a slow leak hope this helps some other members might have a better idea also just wondering what springs you have fitted for a small lift i also would like to lift mine 30 mm from standard while keeping original temms shocks i have 100mm droop now so if my calculations are right if i raise it 30mm i still should have around 70mm droop

mine does the same thing , although if you set it to high it will stay there for days . doesn't worry me . makes it easier for short arses like myself to get in and out . hooked up if you put in lovells hd springs it brings the front up 15-20mm ,then when you go of road you hit the height button for a rear end 40mm lift .

If I have mine set to either Hi or Low, once I get over a certain speed (I think it's either 30 or 40km) the height resets to normal and stays at the normal setting...
