Rebuild the entire block.
If one valve is tired, the others wont be far behind.
I personally would go for Kurt to rebuild it cos then that is it ruled out
Then if still faulty then suspect leaking air line
Would be worth doing the checks you have been advised many times
 
Back again...

So, I got a call from the garage today, apparently i need a new valve block, drive box and a compressor... i wont shock you with the price but....

1) ALL THREE...REALLY!
2) The valve block, I guess it isn't just the solenoids that go wrong on these? there is no air leak, but the compressor gets really hot!
3) ALL THREE!!!!!!!!!
4) what else should i be looking at as there is no air leaks under the car either?
5) when I turn the engine off I get that clicking sound,i can only assume that its from the solenoids in the valve block, if so what are they doing?
6) I can get replacement parts/refurb kits on fleabay, does anyone know anyone who has done this?

other than that!

Bollox.

Pumps fail with time but usually after feeding a leak. Valve blocks do get issues but rare compared to bags or airlines melted by exhaust blow. Driver packs have been known to fail but usually the pins on the connector, the connector behind the passenger kick panel or a height sensor with a dirty track, especially if the wheels have been hanging.

Process of elimination now.
 
And yes a small leak will let air bags down but it would take a major leak to stop it going up in the first place.
My guess is either a knackered pump or a blown exhaust melted the main line to the tank
 
Process of elimination now.

Yes, so going to buy a working complete unit from fleabay,(with 30 day warranty) and then have mine rebuilt (retired engineer father is looking forward to doing this after he watched youtube videos) using rebuild kit. I'm going to reinstall my original after its done. I will keep other as spare and look to refurb at a future date.

will also be buying another pump, and advised to either replace or refurb air dryer.

Will keep you all updated.

Valve block? PM Kurt and see what he has at what price. He had a spare driver pack last I heard too.
