Well after two years of owning my P38 I finally think I am on top of the EAS.
Started with four new airbags.
Progressed to new set of "O" rings in the valve block.
Most of wife's dish washing liquid (looking for leaks)
Removed all airbags and re-cleaned and refitted (used rubber grease to ensure they seat and seal properly.
Fitted manual inflation kit (the one with master gauge pressure) (Andy E)
Fitted a "Battery Angel" to stop flat battery
Fitted new piston/seal kit in compressor
Removed and checked fit of "O" rings many times (Little thin ones around solenoid are tricky and require attention to detail to prevent pinching.
Bought another "low mileage" valve block off e-bay. It seems to have the same fault
Really spat the dummy this weekend, after the above 2nd valve block changed nothing.
Took out the four solenoid valves and drilled out the indented black rubber plug seals.
Used a suitable diameter hollow punch and some 4mm rubber sheet, and made four little rubber plugs.
These were pressed into the brass part where the old plugs were, with a match head size amount of silastic to ensure they don't move.
Refitted the entire unit, pre-inflated the airbags, and added 100psi to the main tank using the above manual inflation valves, cleared and unlocked the EAS using the free software and cable from Mr Wilson.
Fired the beasty up.
Beasty no longer drops overnite, Pump no longer runs lots, thing actually behaves.
I'll crow a little more once a week or so has passed with-out having a flat battery.
Cheers for now
Jeff
