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 A3 8P (2003- ). G18 Описание

Temperature sensor -G18


A - Bolt

B - Clip

C - Overheating cut-out -S24-

D - Temperature sensor -G18-

E - O-ring seal

F - Connector



The overheating cut-out -S24-, the temperature sensor -G18- and the associated wiring form one unit, and can only be replaced together.



K Notes:

JAt 25 °C the resistance of the temperature sensor -G18- is approx. 2.6 KOhm . It decreases as the temperature rises.

JBy way of the resistance of the temperature sensor -G18- the additional heater control unit -J364-

 detects the coolant temperature in the auxiliary heater and controls its various operating states and outputs according to the stored switching temperatures.
