Hello, wanted to ask a question... I have an X5 E53 3.0D. (04 Plate). It has the Air suspension on the rear and the "Selflevel Susp. Inact" error message has appeared on the dash and the rear suspension does not move or inflate.. when i turn the ignition on (not the engine running) i think i can hear the compressor trying to inflate the shocks, but nothing inflates... I have found a BMW X5 E53 Rear Suspension Air Bag to Coil Spring Conversion Kit, which basically a direct replacement rear coil spring kit which completely removes the old air bag suspension... Has anyone done this or basically are they any good? Many thanks in advance..
