    This is the opposite of what most people post with pressurization issues.

    I’ve recently noticed my F1 system is staying primed or pressurized for extended periods of time. The fluid is sucked out of the canister into the system and doesn’t return to the canister for days. I’ll turn the key and there are no F1 lights flashing (priming). I can change all the gears fine.

    In the past, the fluid returned to the canister over night. There are no drive-ability issues, I’m just wondering why the system is staying primed for so long.

    You should hook the car up to a SD2 and watch the pressure readings to see if the pressure is decreasing at each shift (up or down). Car can be sitting still with key on.

    At the next service interval, you may want the technician to run a bleed cycle on the f1 actuator.
