1FB801

What the Code Means

1FB801 (hex 0x1FB801) is stored in the DME (Digital Motor Electronics) control unit, software variant dme8ff_r. Official description: Check Control message (ID 212): Engine oil pressure! Stop the vehicle carefully.

The DME detects engine oil pressure dropping below the permissible level and displays a priority Check Control message with ID 212 on the instrument cluster, requiring an immediate stop. The code belongs to the engine system, and severity is maximum: you can't keep driving with this message until the cause is found.

Symptoms

• Check Control message (ID 212) on the display: “Engine oil pressure! Stop the vehicle carefully.”

Diagnosis and Repair

1. Park the car on a level surface, shut off the engine, check the engine oil level, and fix whatever caused the pressure drop.
2. Check that the birdcage in the oil filter cap isn't damaged or missing. A damaged or missing element prevents the assembly from working correctly and can trigger the message.

Further causes and pressure-testing procedures aren't confirmed by the source data.
