My 2017 SD has air suspension which works fine until cold weather below -4c. On opening the car it sounds like the pump is 'banging' on the passengers side & after a few seconds it stops. After start up the fault appears 'Suspension fault' If you check the fuse in the rear it has blown (40amp). This has occurred a number of times so I wait until the weather is not frosty & replace the fuse. Anyone else had this problem & if so how is it remedied? There must be too much moisture in the system & you worry that eventually the pump will fail
