Air Suspension Issue

Hi, I have a 2005 TD6 Vogue. The wife was out in it yesterday when the "Air Susp, Inactive" warning appeared on the dash & the LED on the suspension control went out. She stopped the vehicle & called me. I told her to continue her journey keeping the speed down. After a while she called again to say the problem had disappeared. On her way home she called again to say that the warning had reoccurred. She had stopped & the AA were called. I met the AA fella at the vehicle & he checked the fuse in the glove box & also the one in the luggage area. When he checked the relay there was a permanent live but no switched live. he disconnected the multiplug connection to the compressor & there was no power there. He "jumped" the relay which fired up the compressor. Could this be due to a malfunctioning Air Suspension ECU? If so whereabouts is this located & how best can it be accessed.
Many thanks for any advice.
Bill.

Usually the ecu locks out power to the compressor and control panel when the compressor has a fault or when its on its way out.
Was the suspension slow to rise before you started getting errors?

I had the same prob with mine, I reset the fault and it's been ok since although I think I will need a new compressor soon.

Hi i had the same problem about a year ago,had to have a new compressor.
