If you are going to install a manual pump up system to make your rover driveable until you figure out the fault, you should bypass the system and connect fill points straight to the airsprings in the same way that the single-mode bypass system works from carroll rovers. Otherwise, its going to keep having problems until the real issue is addressed.

That's aswesome that it was something simple. EAS systems are pretty good for that, simple but infuriating little gremlins that you have to chase around the truck.

If you don't have a way to read/clear the faults you really ought to look into buying or making a serial to OBD II cable and hooking up with the killer free software from rsw solutions. It doesn't just clear the faults but lets you do pretty much everything, the most helpful being the ability to read faults. Its hard to fix a problem without being able to pinpoint which part of the system needs the attention.
Totally worth it.

Also, doesn't hurt to go to work with a spray bottle full of soapy water, a little of that goes a long way.
