Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is on level ground and the engine is cool.
• Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Check and Refill Oil

• Sub-steps:
  1. Remove the dipstick and wipe it clean.
  2. Reinsert the dipstick and pull it out again to check the oil level.
  3. If low, add the appropriate engine oil (typically VW 502.00 or 504.00 specification).
  4. Wait a few minutes, then check the level again and adjust as necessary.

3. Inspect and Replace Oil Filter

• Sub-steps:
  1. Locate the oil filter under the vehicle (usually near the oil pan).
  2. Use an oil filter wrench to remove the old oil filter.
  3. Apply a small amount of new oil to the rubber gasket of the new filter.
  4. Install the new oil filter, hand-tightening it to avoid leaks.

4. Check for Oil Leaks

• Sub-steps:
  1. Start the engine and let it run for a few minutes.
  2. Inspect underneath the vehicle and around the engine for any signs of oil leaks.
  3. Tighten any loose fittings or replace any damaged gaskets or seals as necessary.

5. Replace Oil Pressure Sending Unit (if applicable)

• Sub-steps:
  1. Disconnect the electrical connector from the oil pressure sending unit.
  2. Use a socket to remove the old sending unit from the engine block.
  3. Install the new sending unit, ensuring a proper seal.
  4. Reconnect the electrical connector.
