MBAG initiated an investigation into the issue and determined that incorrect vehicle configuration data had been calculated by the IT-backend of the diagnostics system and written into the control unit of some vehicles. MBAG’s investigation determined that the error in the IT-backend of the diagnostics tool only occurred from July 06, 2021 to July 14, 2021. From August to October 2021, MBAG conducted an extensive investigation to determine which vehicle control units potentially could be affected by the calculation error. This investigation also included an exhaustive review of production and diagnostics records to identify specific vehicles that may have had deviating configuration data installed during a workshop visit. From November 2021 until late February 2022, MBAG performed a detailed investigation and analysis of potential configuration deviations in affected control units to determine if there were any potential effects on safety, compliance and emissions. MBAG has not received any customer complaints or reports of a crash, injury or property damage associated with the software deviation. Nonetheless, on March 11, 2022, MBAG determined that it could not rule out the risk that a deviation in an affected vehicle control unit could pose a risk to safety, compliance and/or emissions.

MBAG initiated an investigation into the issue and determined that incorrect vehicle configuration data had been calculated by the IT-backend of the diagnostics system and written into the control unit of some vehicles. MBAG’s investigation determined that the error in the IT-backend of the diagnostics tool only occurred from July 06, 2021 to July 14, 2021. From August to October 2021, MBAG conducted an extensive investigation to determine which vehicle control units potentially could be affected by the calculation error. This investigation also included an exhaustive review of production and diagnostics records to identify specific vehicles that may have had deviating configuration data installed during a workshop visit. From November 2021 until late February 2022, MBAG performed a detailed investigation and analysis of potential configuration deviations in affected control units to determine if there were any potential effects on safety, compliance and emissions. MBAG has not received any customer complaints or reports of a crash, injury or property damage associated with the software deviation. Nonetheless, on March 11, 2022, MBAG determined that it could not rule out the risk that a deviation in an affected vehicle control unit could pose a risk to safety, compliance and/or emissions. Accordingly, MBAG will conduct a recall of affected vehicles.
