Logic of naming sensors in VW-group is simple it contains "G" (german "Geber") + sensor number. The sensor number is unique. Here you can find fitting location, connectors and pins description, some information about sensors signals.

To our mind, sensors information is reference, so there is only simple search by sensor number.

Audi R8 42 (2007- ). G151 Описание

Right vent temperature sender -G151


1 - Defroster flap control motor -V107

2 - Right vent temperature sender -G151

3 - Evaporator out-flow temperature sender -G263

4 - Footwell flap control motor -V261

5 - Front cold air flap control motor -V197


The climate control is fully automatic, with separate temperature control for the left and right sides of the passenger compartment. The right vent temperature sender -G151 is always fitted in the air duct to the right dash panel vent. The air flowing out of the heater/air conditioner unit into the passenger compartment is recorded with a temperature-dependent resistance and so is available as an influencing variable in the temperature monitoring and control function of the Climatronic control unit -J255. The right vent temperature sender -G151 is designed as an NTC sensor. As the temperature falls the electrical resistance increases. The resistance is evaluated as a signal by the Climatronic control unit -J255, and is used to regulate the air distribution and the blower flow rate.


YZ Note:

Experience shows that temperature senders are the most frequent cause of temperature control faults. They do not usually fail immediately, but deliver false values to the control unit based on an additional wire resistance as a result of damage or corrosion in the connector contacts. Thus a comparison of the values of more senders (-G150 and -G151, -G263) in the relevant display zones is recommended for optimum diagnosis.
