Hi Robin. Thanks for your reply, but no it not that unfortunately.

Hi All, I've now read through a whole load of posts already, but struggling to find a match to my issue. Passenger side low, drivers side normal hight. Already checked all 4 sensors, giving a good and same read (multimeter) on each sensor. Compressor running on start up, (after the trick of stopping and starting the car a number of times). Does not raise the car, either side. I have a Bosal towbar fitter where a tube from the compressor connects to the side of the towbar with replaces the original tank. If I disconnect this pipe and can get the car to raise and lower on the button in the car. When I reconnect the pipe the can on passenger side then drops back to low position. I've disconnected the battery for 30 mins (no effect). What does the tank/reservoir do? I've pressure tested with a footpump and got up to almost 3 bar. What am I missing???? Thanks
