Heating System Heat Exchanger Sensor
WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2008 BMW 760Li, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The sensor is integrated in the heating/air-conditioning system. On the IHKA Basic, the sensor measures the delivery temperature on the driver's side, directly on the delivery side of the heating system heat exchanger. On the IHKA High, 2 sensors are installed as the delivery temperatures are measured separately at the heating system heat exchanger for the driver's side and for the front-passenger side.
