paul.h Posted August 11, 2016 Posted August 11, 2016 Welcome to the forum. Possibly the rear height sensor is sticking or one of the rear strut seals is leaking so the pressure can not be maintained. You could also check the level in the lds tank - with the suspension on the low setting the fluid should just cover the bottom of the tank filling neck strainer. Do not go under the car without using axle stands to support the body since if a height sensor is caught the suspension can quickly drop the car to a low level. Quote
