Instrument Panel Temperature Sensor -G56-, Removing And Installing: Notes
The Instrument Panel Temperature Sensor -G56- -2- is only installed on vehicles with an automatic climate control system. The opening in the storage compartment (or in the knee bar) on the driver side is sealed off with a closure cap that has no electrical function on vehicles with a manual climate control system.
The Instrument Panel Temperature Sensor -G56- -2- calculates three different measured values that cannot be checked with service equipment. From these measured values the Climatronic Control Module -J255- calculates the temperature in the vehicle interior. Depending on the ambient conditions, the three calculated measured values may deviate from each other and only begin to come closer together after a longer period of operation or remaining stationary. Use the Vehicle Diagnostic Tester in the"Guided Fault Finding" function.
A dirty sensor head on the Instrument Panel Temperature Sensor -G56- -2- or a dirty or taped off opening in the storage compartment (or knee bar) -4- causes problems when regulating the A/C system. Use the Vehicle Diagnostic Tester in the"Guided Fault Finding" function.
