TPI Summary TPI No.: 2064808/6 Inappropriate "Low Oil Level" Display
Release Approval Date: June 3, 2024
- Customer Error Description/Station Conclusion Customer Complaint: The message "Please reduce oil level. Workshop!" appears on the dashboard. Workshop Conclusions: Please reduce the oil level. The "Workshop!" message appears even though the oil level is correct.
- Technical Explanation: For the engine control unit to detect a drop in oil level after the message "Please reduce oil level. Workshop!" is displayed, the oil level must be significantly lowered. This threshold is too high in the current software. Despite the correct oil level, the message reappears after a single overfill. Opening the hood resets the oil level sensor, and the message remains off for at least 100 km. The software does not remove the message from the dashboard but makes it easier to reset. The message appears when the oil level in the oil pan is 10% above the normal value. However, pumping out engine oil to correct the oil level is not recommended if the fuel is diluted. The limit here is 10%. As soon as this 10% value is artificially lowered, for example, by an improperly performed oil change or uncontrolled oil filling by the workshop or the customer, the "maximum oil level detection" is triggered much sooner than necessary.
- Solution under production conditions: Software solution with a lower response threshold for the oil level sensor
- Solution according to the terms of use: Update the engine control unit software via the "Software Version Management (SVM)" menu.
