Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather all necessary tools and parts for the repair.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to manufacturer's specifications (typically around 25 Nm).
4. Fill the engine with fresh oil that meets BMW specifications (typically 5W-30).

3. Inspect and Replace VVT Solenoid (if necessary)

Tools Required: Socket set, ratchet, torque wrench, new VVT solenoid.
Sub-steps:
1. Locate the VVT solenoid (usually on the engine cylinder head).
2. Disconnect the electrical connector from the solenoid.
3. Remove the mounting bolts and carefully take out the solenoid.
4. Install the new VVT solenoid and torque the bolts to approximately 10 Nm.
5. Reconnect the electrical connector.

4. Check Timing Chain/Belt

Sub-steps:
1. Remove any covers obstructing access to the timing chain or belt.
2. Inspect the chain/belt for wear, slack, or misalignment.
3. If necessary, replace the timing chain/belt, following the manufacturer's service manual for specific procedures and torque values.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear the trouble codes and reset the check engine light.
