Discovery 2 Rear Air Suspension Failure

Popped in to see a mate of mine to find him under his disco 2, which
has dropped to its bump-stops.

On doing some simple trouble shooting it seems that the compressor is
running properly, but the single solenoid valve at the fron of the
compressor is delivering the air direct to the "exhaust" rather than
forward to the two other solenoid valves which feed the rear air
springs.

Have tried un-plugging the valve, but this seems to prevent the
compressor running.

Compressor is nearly new (supplied by that nice chap at Beamends!).

Anyone had this before or recognise the symptoms?

I would guess either the solenoid valve is faulty, or the electrickery
which sends a signal to the solenoid has thrown a fit.

Thoughts anyone?

Had a problem like that with my limo, turned out to be some plastic joint
which I was not able to replace as the system had long since ceased to be
manufactured, but araldite fixed it. Check for leaks.

Resolution

Looks like either the exhaust solenoid or the pressure relief switch
(both part of the compressor assembly) had got gunked up.

Stripped, cleaned and re-assembled and the things right as rain.

Had the air bags in my Disco deflate on day 9 of receiving it from the
dealer. Depressing (pardon the pun)!

Was told by the dealer the solenoid had physically failed (can't recall
anything more specific--I don't think they gave many details).

Since then I've had no probs--with the suspension, that is. Problems
with bonnet opening while in motion (see current thread), turbo hose
disconnecting at highway speed, water leaks, electric seats cutting
their own wiring and short-circuiting, ABS/TC/HDC lights coming on for
no apparent reason.
