Summary

Complaint When the pre-entry climate control was activated via Mercedes me connect App, the driver no longer had access to a cooling output for the vehicle interior once the vehicle had started. Cause If pre-entry climate control is activated, the engine fan should switch on to regulate corresponding temperature and pressure rises in the refrigerant circuit. Since the engine fan is not switched on, high pressure (overpressure) can arise in the refrigerant circuit and consequently switch it off. Remedy Software update in drivetrain control unit (PTCU) Should further complaints arise after the software update, please create a TIPS case with the following information: • The customer complaint in detail • Current quick test • Refrigerant filling quantity • Actual values for climate control at the time the complaint occurs • High and low-pressure values at the time the complaint occurs
