Drive the 5 Zyl Turbo, my air conditioning has a Macke,,, after start of the car I have cold air for about 5 minutes, then the luxury stops… when the air conditioning is running, I can also hear how the compressor goes on and off, if I give at the switch according to command After 5 minutes there is nothing more,,, no climate.. no cold air, no CLICK noise of the compressor at switching speed… but a 5 – 10 minute break is enough, then it starts again… but just again only for 5 minute n, the game starts from the front The error memory has nothing to report.. NULL error Where should I start troubleshooting ?
