Bit of a desperate long shot; but does anyone in the sane vicinity of Tonbridge happend to have a spare known good P38 EAS pump and valve block unit or even just the Driver Pack I could perhaps borrow/buy to test my suspension?

I'm having a battle trying to get my EAS system working after a complete overhaul on a P38 that I bought with a blown air spring. At present it will only inflate, and won't go down so I'm trying to figure out why the Exhaust Solenoid isn't activating
