Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to remove the valve cover breather tube in this 2007 Audi A4. You'll need a flat blade screwdriver, 5mm stubby Allen socket, a ratchet, and a universal joint.
The valve cover breather tube is located on the front passenger side of the engine and runs from this rubber hose on the valve cover down to the inlet side of the turbo. Be sure that the engine is cooled down before removing the tube because it connects to the backside of the turbo which gets very hot very quickly. Ensure the vehicle is fully cooled down.
Use a flat blade screwdriver to loosen the clamp at the top of the breather tube. Remove the breather line from the rubber hose. Remove the two 5mm Allen screws holding the bottom of the tube into the back of the turbo. You'll need a stubby Allen socket and a universal joint.
To remove the lower bolt, we're just going to use a long straight extension and the stubby Allen socket. Start the bolt through the bottom of the breather line. Line up the bolt. Start the top bolt by hand. Once the bolts have been started, and the flange is lined up, tighten them down.
While you need to use extensions and universal joints in order to remove and install these bolts, they can throw off the accuracy of a torque spec. If you'd like, the torque spec for these is 80 inch-pounds.
Reinstall the top of the breather line into the hose. With the ventilation line reinstalled into the rubber hose, tighten your clamp with a flat blade screwdriver.
