moin in the round, you had to do over Easter all at the car so I waited until AFTER Easter. problem….climate does not cool…………. April 2019….over a workshop with appropriate device to fill….was held until August 2019 August 2019 over another workshop climate inspection, especially let the connection nozzles test… via the device emptied….vacuum built up….and refilled. The air conditioner has not detected any leak…. question? what to do??? Ka Can I check the climate for tightness?? HOW? e.g. in the auto-self-help compressor seems to be tight…have searched with lamp for greenish outflow Can I check if there is still coolant in the system? The comp only starts when it gets notification that the system has sufficient coolant…. can I bridge the one that it starts?? Did not find the right search here over Easter… Would be very pleased and grateful about antores…. Week you lg Wolfgang
