Whenever my auto box is in gear - engine running or not - something electrical between the engine and the bulkhead runs continously and noisily.
By pulling fuses I have discovered that the culprit is the "Vacuum/Air Pump" - presumably charging the brake servo.

Is this continuous running normal? (Maybe it always ran all the time but I didn't notice until it became noisy). If not, where to look for a pressure sensor which would turn it off when its done its job.

The wretched Haynes manual does not even admit to its existence so no help from there.

Thanks

Should really only run when your foots on the brake.
