BMW 3: Engine oil

General information

The engine oil consumption is dependent on your driving style and driving conditions.

Therefore, regularly check the engine oil level after refueling by taking a detailed measurement.

The engine oil consumption can increase in the following situations, for instance:

  • Sporty driving style.
  • Break-in of the engine.
  • Idling of the engine.
  • With use of engine oil types that are classified as not suitable.

Different Check Control messages appear on the Control Display depending on the engine oil level.

Safety information

NOTICE An engine oil level that is too low causes engine damage. There is a risk of damage to property. Immediately add engine oil.

NOTICE Too much engine oil can damage the engine or the catalytic converter. There is a risk of damage to property. Do not add too much engine oil. When too much engine oil is added, have the engine oil level corrected by a dealer's service center or another qualified service center or repair shop.

Electronic oil measurement

General information

The electronic oil measurement has two measuring principles:

  • Monitoring.
  • Detailed measurement.

When making frequent short-distance trips or using a dynamic driving style, for instance when taking curves aggressively, regularly perform a detailed measurement.

Monitoring

Concept

The engine oil level is monitored electronically while driving and can be shown on the Control Display.

If the engine oil level is outside its permissible operating range, a Check Control message is displayed.

A red indicator light indicates that the engine oil pressure is too low.

Functional requirements

A current measured value is available after approx. 30 minutes of normal driving.

Displaying the engine oil level

Via iDrive:

1. "CAR".

2. "Vehicle status".

3. "Engine oil level".

The engine oil level is displayed.

System limits

When making frequent short-distance trips or using a dynamic driving style, it may not be possible to calculate a measured value. In this case, the measured value for the last, sufficiently long trip is displayed.

Detailed measurement

Concept

The engine oil level is checked when the vehicle is stationary and displayed via a scale.

If the engine oil level is outside its permissible operating range, a Check Control message is displayed.

General information

During the measurement, the idle speed is increased somewhat.

Functional requirements

  • Vehicle is parked in a horizontal position.
  • Steptronic transmission: selector lever in selector lever position N or P and accelerator pedal not depressed.
  • Engine is running and is at operating temperature.

Performing a detailed measurement
