Complaint Check engine warning light active. Fault code P300CA8 or P300CA9 "Hot film mass air flow sensor malfunction" is present in engine control unit. Cause a) In the case of fault P300CA8: • Due to incorrectly installed component parts of the clean air line between the air filter box and the exhaust gas turbocharger, it is possible that leaks may occur in the system which subsequently result in air mass faults • A fouled air filter or leaks in the intake or charge air system downstream of the exhaust gas turbocharger may also cause these faults. b) In the case of fault P300CA9: • Computational model for programmed values of air intake, in particular, for the high load mode, calculates this high load correction programmed value incorrectly. This leads to the programmed value drifting too quickly towards the limit. Remedy Install the following add-ons: 18937 for XENTRY 12/2020 18938 for XENTRY 03/2021
