Al-Ko AMC air suspension

[simonjfoley]

Hi all, my 2004 Hymer B654 , on a Ducato - Al-Ko AMC chassis , is giving a spot of trouble at to moment, in that the automatic air suspension in the back axel seems to have just died overnight, not a tinkle from the compressor which usually fires up when I start the engine.
There’s power at the controle pad on the dash, and there’s a clank from the compressor when I press the up or down button,. If anybody has anything on this ,It would be much appreciated . Many thanks .
