why is my Volkswagen Golf Eighth Generation (2020-present) exhaust smell so strong

Solution

1. Preparation

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

2. Inspect and Repair Exhaust System

1. Visual Inspection:

   • Inspect the exhaust pipes, muffler, and catalytic converter for visible cracks or holes.
   • Check joints and connections for any signs of leakage.

2. Repair Leaks:

   • If any leaks are found, use exhaust tape for small holes or replace damaged sections of the exhaust pipe.
   • For larger leaks or if the catalytic converter is damaged, replace it with a new unit.

3. Address Fuel System Issues

1. Check for Leaks:

   • Inspect fuel lines and connections for any signs of leakage.
   • Replace any damaged fuel lines or connectors.

2. Clean Fuel Injectors:

   • Use a fuel injector cleaning kit or professional service to clean the injectors if they are clogged.

4. Replace Faulty Sensors

• If diagnostic codes point to faulty oxygen or other relevant sensors, replace them with OEM parts according to manufacturer specifications.

5. Check and Clean Engine Components

• Remove the intake manifold (if necessary) and inspect for carbon buildup. Clean using a suitable carbon cleaner.
• Reassemble and ensure all connections are secure.
