If there is a noticeable change on the consumption (from 0.7 to 1.3l /h approx) your compressor will be apparently ok and the gas too.
If the value doesn't change at all, your compressor is not engaging properly. It could be for many reasons, but you should diagnose the car and check the IHK and JBBF codes.


Thanks Jose. On normal parked car consumption varies from 0.7-1.2l/h on my car and when I turn on car, it goes to 1.3l/h.

So I reckon compressor is working but possible gas is low.
Why would gas go low? Leakage in compressor or somewhere?
