Sub-steps:
1. Remove the engine oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If low, drain the old oil using an oil pan, and replace it with new oil that meets BMW specifications (typically 5W-30).
4. Replace the oil filter with a new one, ensuring O-ring is lubricated before installation.

Tools Required: Socket set, oil filter wrench, oil pan.

3. Inspect and Replace Oil Pressure Sensor

Sub-steps:
1. Locate the oil pressure sensor (usually near the oil filter).
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using a socket or wrench.
4. Install a new oil pressure sensor and reconnect the wiring harness.

Tools Required: Socket set, torque wrench.

4. Check and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the oil pan to access the oil pump.
2. Disconnect the oil pickup tube and remove the oil pump mounting bolts.
3. Replace with a new oil pump, ensuring proper alignment.
4. Reinstall the oil pickup tube and oil pan, using a new gasket if needed.

Tools Required: Socket set, gasket scraper.
