Self Level Susp Inactive Woes

[ngary]

Hi,

Ive no doubt there are reams of threads on this - but Im not great with PCs...so apologies in advance if its a routine problem.

Had this message appearing on/off - seemed to reset when I restarted the car. Battery died the weekend when away so I changed it for a new one - now this message is present constantly and rear of car is low and doesnt rise.

It a 2002, 3.0 diesel sport with air at rear only.

Ive checked the 7.5 and 30 amp fuse in boot area - all OK. When I replace the 7.5 fuse the pump in the air tank makes a 3 second buzzing noise....but doesnt really seem to engage.

Is there anything else I can check before I take it for diagnostics check, a colleague suggest is the air pump thats gone...

Any help appreciated, boy this is turning out to be a very expensive motor !

Cheers

gary
