Mine has done that since I got it three years ago. I have had it on RSW, Testbook and Autologik (I think). None of them show faults however I once got a 'bad connection' on a height sensor. This was sorted and didn't show up again. It can go days without any problems, staying at normal ride height then lowering at motorway speed and coming back up again on slowing. Sometimes it forgets to stop and rises to wade or extended with the top light flashing. It can be caught if I notice it right away but if I let is rise completely it will take a few minutes to revert to standard. Sometimes if I am carrying a load or pulling a trailer it will behave which makes me think height sensors. It's as though it senses bottoming out and rises which is normal but it's quite annoying when on a level straight road. In the past year I have replaced the pump and air springs and re-calibrated all the heights as per the above chart. It did it again tonight on the way home. It will be interestig to follow this thread for a new slant on what the cause could be.
