Audi B8 S5 Intake Removal for Carbon Clean

Introduction

This tutorial guides you through the process of removing the intake from a 2009 Audi S5 with a 4.2 V8 engine to facilitate a carbon clean. This procedure is essential for maintaining engine performance and efficiency, particularly in vehicles prone to carbon buildup.

Step 1: Gather Necessary Tools and Materials

Before starting the intake removal process, ensure you have the following tools and materials:

• Socket set (including 10mm and 13mm sockets)
• Torx bit set
• Pliers
• Flathead and Phillips screwdrivers
• Vacuum cleaner with a hose attachment
• Carbon cleaning kit (optional)
• Clean rags or towels

Step 2: Disconnect the Battery

Safety first! Always disconnect the battery before working on your vehicle to prevent any electrical issues.

1. Open the hood and locate the battery.
2. Use a wrench to disconnect the negative terminal.
3. Secure the terminal to prevent accidental reconnection.

Step 3: Remove Engine Covers

To access the intake, you must first remove the engine covers.

1. Locate the clips and screws holding the engine cover in place.
2. Use a screwdriver or socket to remove them.
3. Carefully lift off the cover and set it aside.

Step 4: Disconnect Air Intake Duct

Next, you will need to detach the air intake duct from the throttle body.

1. Identify the clamps securing the duct to the throttle body.
2. Use pliers to loosen the clamps and disconnect the duct.
3. Remove any sensors or hoses attached to the duct.

Step 5: Remove the Intake Manifold

Now, you can proceed to remove the intake manifold itself.

1. Identify and remove any bolts securing the manifold (typically 10mm).
2. Carefully unclip any electrical connectors or vacuum lines attached to the manifold.
3. Lift the manifold off gently, being cautious not to damage any gaskets.

Step 6: Inspect and Clean

With the intake manifold removed, inspect it for carbon buildup.

1. Use a vacuum cleaner with a hose attachment to remove loose debris.
2. If carbon buildup is present, consider using a carbon cleaning kit for thorough cleaning.

Conclusion

You have successfully removed the intake from your Audi S5 for carbon cleaning. Remember to check all components for wear and replace any damaged parts before reassembly.
