• RPM info missing (can no longer be determined, since compressor RPM can no longer be measured).
• Speed signal implausible signal (vehicle speed is transmitted via "Data-Bus drive" from instrument cluster).
• Outside air temperature sensor -G17- (measured temperature -G17- is transferred via the Data-Bus from instrument cluster).
• Evaporative Emission (EVAP) Flap Motor Position Sensor -G114- (activated charcoal-flap and thereby position sensor are not introduced).
• Evaporative emission flap motor -V114- (the activated charcoal-flap is not introduced).
• A/C high pressure switch (in A/C clutch) -F118- (replaced by pressure switch -F129-).
• A/C clutch -N25- (after sensor -G111- is deleted, malfunctions to A/C clutch can no longer be recognized).

• Control module incorrectly coded.
• Basic setting not conducted.
• Data Bus drive faulty.
• Engine control module "No communication" or "Check DTC Memory."
• Control module in instrument cluster "No communication" or "Check DTC Memory."
• Interior temperature sensor fan -V42- is installed into A/C control head -E87- with part numbers beginning with index letter "M," and can not be replaced individually.
• Instrument panel interior temperature sensor -G56- is installed into A/C control head -E87- with part numbers beginning with index letter "M," and can not be replaced individually.
