why is my Volkswagen Golf Eighth Generation (2020-present) check engine light on after oil change

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Gather necessary tools and parts for the repair.
• Disconnect the battery to avoid any electrical issues.

2. Inspect and Tighten Components

• Oil Filter:
  • Remove the oil filter and inspect the rubber O-ring for damage.
  • Apply a thin layer of oil to the O-ring and reinstall the filter, tightening it to manufacturer specifications (usually hand-tight plus a quarter turn).
• Drain Plug:
  • Inspect the drain plug for proper torque (typically 20-25 Nm).
  • Retighten the drain plug if loose, ensuring no oil leaks are present.

3. Clear Error Codes

• Reconnect the battery after repairs.
• Use the OBD-II scanner to clear any existing check engine light codes.
• Ensure to note any codes for future reference if they reappear.
