Malfunction lamp for On Board Diagnostic (OBD)/Malfunction Indicator Lamp (MIL) -K83- in instrument cluster: Function
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2004 Audi A6, 2003 Audi S6, 2003 Audi A6, 2002 Audi S6, and 2002 Audi A6. However, it is still accessible from the selected car via links, so may be relevant.
After switching on the ignition, the ECM switches on the Malfunction Indicator Lamp (MIL) -K83-. Shortly after engine is started, the Malfunction Indicator Lamp (MIL) -K83- will go out. This requires, first of all, that the Engine Control Module (ECM) does not detect a malfunction that worsens the emissions values and, secondly, that activation of the lamp by the Engine Control Module (ECM) is OK.
