    E46 coolant leak, no preassure under preassure test

    My 02 2.2 wagon is leaking coolant.
    Changed the upper radiator hose as that was leaking but still problems.
    I've tried a preassure tester, but there is no preassure at all (nothing wrong with the tester, tested on my e46 convertible without any problems).
    No visible leaks, no engine problems.
    Ideas?

    Is the system full?

    I would see about pulling sparkplugs and having a look inside the chambers.

    Also there is a plastic coolant hose that runs under the intake, you have to use a mirror to see if that one is leaking.

    How long does it take before you need to add coolant again

    Does the coolant low lamp come on? I have to add about ,25l every couple of months to the wagon, and it has been doing that since new. What I found out is you don't fill it to the full line, but to the min line, and you won't lose as much.
