100/80:

To add to what George said, mine has always timed out in around 9-11 minutes (both the Graphite and the SE, not sure how long on the first car).

But like I said, if you power down the module/pump, the solenoids relax and their relaxed state is to open up and allow all pressurized fluid to flow back to the tank. Actually, I learned this by mistake, this spring, I started the pump and the rear window bow raised up and then the lid raised 3 inches or so, then the battery voltage sagged and the system froze. I could not get it to do ANYTHING, and the pressure meant I could not manually recover. I had no time to grab the book, and thought I'd reset the system wiht a battery disconnect.

First thing I saw, was that the system relaxed and the pressure released, the lid went back down and the bow slowly settled.

That was the day I realized that a 'relaxed' system was a De-pressurized system. It was later I got into the manuals and found the fuses, but I"ve never pulled fuses to see how effective it is (nor which of the two or both it takes).
