This morning the car is 1" lower both left and right sides. The 2 electric L&R rear (Y53/1, Y54/1) valves must be opening to let pressures out. My understanding was they would be closed only being operated when level adjustment is required. After I jacked the near side up yesterday to fit brake pads on lowering the car sat slightly higher until 10 seconds (Approx) after locking the car Airbag valve click and air released then another click and air stopped. The car was then at the correct height until this morning.
Are the valves open with pressure in the lines all times And I have a Leak
