Land Rover LR3 Air Suspension Diagnosis

In episode four I diagnose the inoperable air suspension on our 2006 Land Rover LR3. I discover the ECU is running the wrong air compressor firmware and demonstrate the step by step process of updating it. I then discover a significant air leak in one of the valve blocks and show how to change the o-rings on all three. By the end of the video the air suspension is functioning and raises the vehicle to “off-road” height.
