Conditions:
- on-board voltage > XXV
- engine speed = X rpm
- air-conditioning vents = open
- recirculation = OFF
- air-conditioning = -Lo-
- air-conditioning vents - air distribution at centre + legroom
- air-conditioning = OFF (ECON = ON)
- ventilation = MAX
connect with the control unit XX - Air-conditioning
XX - Measured values group XXX
required values
field X = ambient temperature - actual value
if values are not achieved - check component:
- temperature sensor GXX (ambient temperature)
- line
