Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting any electrical work.

2. Change Engine Oil

Step 1: Remove the oil drain plug using the socket set.
- Safety Warning: Allow engine to cool before draining oil to avoid burns.
Step 2: Drain the old oil into a suitable container.
Step 3: Replace the oil filter using an oil filter wrench.
Step 4: Reinstall the oil drain plug and torque to manufacturer specifications (usually around 25 Nm).
Step 5: Refill the engine with the recommended oil type and quantity for the BMW X5 G05.

3. Replace Oil Pressure Sensor (if necessary)

Step 1: Locate the oil pressure sensor, typically near the oil filter.
Step 2: Disconnect the electrical connector from the sensor.
Step 3: Remove the oil pressure sensor using a socket or wrench.
Step 4: Install the new oil pressure sensor and tighten to manufacturer specifications (usually around 15 Nm).
Step 5: Reconnect the electrical connector.

4. Inspect and Replace Oil Pump (if necessary)

Step 1: Remove any components obstructing access to the oil pump (engine covers, etc.).
Step 2: Disconnect the oil pump from the engine and remove it.
Step 3: Install the new oil pump, ensuring proper alignment and securing it with bolts to the manufacturer's torque specs.
Step 4: Reassemble any components that were removed.
