Center Vent Temperature Sensor

Center Vent Temperature Sensor

• As of model year 2006, the Center Outlet Temperature Sensor (G191) has been gradually discontinued, on vehicles without this sensor, only the Climatronic Control Module (J255) A/C control head with part no. 4F1 820 043 as of index "M" (vehicles with left-hand steering), or 4F2 820 043 as of index "F" (vehicles with right-hand steering), is or may be installed.

• In vehicles without Center Outlet Temperature Sensor (G191), if a Climatronic Control Module (J255) with part no. 4F1 820 043 up to and including index "L" (vehicles with left-hand steering), and similarly with part no. 4F2 820 043 up to and including index "E" (vehicles with right-hand steering), is installed, the missing sensor is displayed as a malfunction.

• The Climatronic Control Module (J255) A/C control head with part number 4F1 820 043 as of Index "M" (for vehicles with left-hand steering) or 4F2 820 043 as of Index "F" (for vehicles with right-hand steering) has been installed since 5/2005 as a rolling change in vehicles with the Center Outlet Temperature Sensor (G191) (the sensor's measured value is no longer required for control by these A/C control heads and therefore no longer evaluated).
