how do I fix my Volkswagen Golf MK7 (2015-2019) exhaust leak

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

• Lift the vehicle using a jack and secure it on jack stands.
• Ensure the vehicle is stable before proceeding.

3. Locate the Leak

• Use a flashlight to inspect the exhaust system thoroughly.
• If necessary, use the smoke machine to pinpoint the exact location of the leak.

4. Repairing the Exhaust Leak

a. If the leak is at a joint or clamp:

• Remove any loose clamps or bolts using a socket set.
• Clean the surfaces to ensure a proper seal.
• Replace with a new clamp or bolt and torque to manufacturer specifications.

b. If the leak is in the exhaust pipe or muffler:

• Cut out the damaged section using a reciprocating saw.
• Prepare the new section of exhaust pipe (if replacing) by measuring and cutting accordingly.
• Use exhaust pipe cement or a gasket to seal the new section in place.
• Secure with new clamps and ensure all connections are tight.

c. If the leak is at the exhaust manifold or gasket:

• Remove the heat shield (if present) using a socket set.
• Detach the exhaust manifold from the engine by removing the bolts.
• Replace the old gasket with a new one and reattach the manifold.
• Torque the bolts to manufacturer specifications.

5. Final Checks

• Reinstall any components removed during the process (heat shields, underbody covers).
• Lower the vehicle back to the ground and reconnect the battery.
