It may be worthwhile checking the dryer for air leaks and checking the contents.
Undo the airbag feed pipes from the block.
Then try to raise the car, if they all blow air then the problem is further on.
If they don't, then the problem is possibly in the block.. None return valves the right way round?

Think the OP needs to go through everything again and make sure all is correct in the valve block. If the compressor is running for seven or eight minutes producing good air then stopping that air has to be going somewhere.
 
As I have already said if the tank is full there is more than enough air to raise the car to standard height. No air is going in the tank.
If that were the case the compressor would not stop after 7/8 minutes and restart when the door is shut and the car tries to lift. If the compressor stops from an overheat it will not restart after the time it takes to get into the car and shut the door.
It should throw a fault but we do not know if the OP resets with his kicker between attempts..

And therefore the high volume leak should be audible. A low volume leak from the fill line will not be. We don't know if the OP has carried out his valve block refurb correctly. My observations are based on everything being serviceable and as they should be. Normally and if all is good otherwise, access lamp on and goto height flashing is lack of air pressure. Which should produce a double fault of both rear valves stuck closed. As far as i am aware the EAS kicker does not record any faults but acts in the same manner as the Syncmate. And relays it's info through a series of flashing green and red lamps.

In the car door shut and engine running would the OP have any chance of hearing a leak? I doubt it.
 
nanocom lets you energise the compressor with engine off, does eas kicker do this too? would be easier to trace a leak with no engine noise

He could always shut the door and stand outside that amount of high volume air has to be audible. As said, if EAS system is working correctly goto lamp flashing is lack of air pressure. Plain and simple.

I agree, à revision may well be needed to confirm:D
 
An odd thing that happened to a chap i know who has a P38..

The car was on its bumpstops and the compressor worked, we looked underneath the the bags were blowing out like balloons..

Making no effort to lift the car, they just blew out sidewards!

Odd.
 
Nobody has surgested a soapy water spray to check for bubbles, or perhaps they have, and bridging relay 20,pins 3 and 5 to run the compressor without the engine running.

At the beginning he said it stayed up for 4 days when the bags were inflated with a compressor, so it is quite likely that the airbags are perished and is probably why the compressor needed replacement.
