1. Remove the oil drain plug with a socket set and drain the engine oil into a suitable container.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to the manufacturer's specifications (typically 25 ft-lbs).
4. Fill the engine with new oil that meets VW specifications (usually 5W-30 synthetic oil).
5. Start the engine and let it run for a few minutes, then check for leaks.

3. Replace VVT Oil Control Valve

Sub-steps:
1. Locate the VVT oil control valve (usually on the engine's cylinder head).
2. Disconnect the electrical connector.
3. Remove the retaining bolts and take out the valve.
4. Install the new VVT oil control valve and torque the bolts to manufacturer specifications.
5. Reconnect the electrical connector.

4. Check Camshaft Timing

Sub-steps:
1. Remove necessary components to access the timing chain/belt (e.g., timing cover).
2. Align timing marks according to the manufacturer’s specifications.
3. If misaligned, adjust the timing chain/belt or replace if worn.
4. Reinstall the timing cover and any components removed.

5. Clear Codes and Test Drive
