1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent any electrical short.

2. Change Oil and Filter

1. Drain the Engine Oil:
   • Remove the oil drain plug using a socket wrench.
   • Allow the oil to fully drain into a suitable container.
2. Replace the Oil Filter:
   • Use an oil filter wrench to remove the old oil filter.
   • Lubricate the rubber gasket of the new oil filter with a bit of new oil and install it.
3. Refill Engine Oil:
   • Replace the drain plug and tighten it to the manufacturer’s specifications (typically around 25 Nm).
   • Fill the engine with the recommended oil type (e.g., BMW Longlife 01 or 14) up to the proper level.

3. Replace VVT Solenoid

1. Remove Engine Cover:
   • Use a socket set to remove bolts securing the engine cover and carefully lift it away.

   • Reconnect the electrical connector.

4. Check Timing Alignment

1. Remove Timing Cover:
   • Use a socket set to remove the bolts securing the timing cover and set it aside.
2. Verify Timing Marks:
   • Rotate the engine to TDC (Top Dead Center) and ensure timing marks on the crankshaft and camshaft gears align correctly.
3. Adjust Timing if Necessary:
   • If misaligned, adjust the timing chain/belt according to the service manual specifications.

5. Reassemble and Reset Codes

1. Reinstall Timing Cover:
