Step 1: Jack the front end up
First and foremost, jack the front end of the car up. This will make it easier to take off the bumper. It is not necessary, but you will see why we did it this way in a bit. Place 2 jack stands on the front pinch welds.
Step 2: Remove Drivers side wheel
Remove the drivers side wheel for now. Breaker bar and 17mm socket to remove lugs. We will come back to it in a bit.
Step 3: Remove belly pan
Crawl under the front of the car and remove the belly pan. There are several bolts holding it in. Grab your flat head and twist them out.
Step 4: Remove Intake Snorkle
Lets start with the passenger side and remove the intake snorkel. Grab your philips screw driver and remove the two screws holding the snorkel in place.
Once the screws are out, disconnect it from the car.
Step 5: Remoe Airbox adapter
Now take the adapter out that is shown above. To do so simply pull upward away from the air box.
Step 6: Remove Headlights
Next step is to remove the headlight. There are four TORX30 bolts holding the headlight in. The top two need to be completely removed. The rear ones only need to be loosened in order to remove the headlight.
To reach the rear two TORX30 bolts, grab your 3/8 rachet with a 6" extension.
Once the top bolts are removed and the rear two are loose, pull the headlight assembly forward. Time to disconnect the headlight harness. It can be a pain, please follow the link below for a video on how to do it.
Video to remove harness
Once the harness is disconnected, remove the head light from the car. Follow the same procedure for the drivers side. Below is a picture where the hidden TORX30 bolt is.
Once both headlights are removed you can pull the weather seal off the engine bay.
Step 7: Remove Fender Liner Bolt
Okay, move to the passenger side wheel well. To make things easier, cut the wheel to the left to make room. Grab your stubby flat head and remove this fender liner bolt.
Once that is removed, pull the fender liner back to reveal this TORX25 bolt. Grab your 1/4 ratchet and TORX25 socket and remove it.
Step 8: Free Lower Bumper from Fender
Once that is removed, its time to pull the lower half of the bumper away from the fender. Review the image below. Slightly pull the lower portion of the bumper toward you. It will give away from the tabs.
Step 9: Follow the same procedure for the drivers side.
Step 10: Remove Inner Fender Bolts
Okay your done on the bottom half for now. Back to the passenger side. Take a peak on the inner fender where the headlight was. You will see three 10mm nuts down the side of the fender. Grab a 10mm ratchet wrench and remove these three bolts as shown below.
Okay lets go back to the driver side now. You can either follow our way or do it the other way. The problem with the drivers side is that the three 10mm bolts connecting the fender and bumper are difficult to get to. Its clearly not as easy as the passenger side. You can either work in the tight space to remove the bolts or follow the next instructions. If you remove the bolts here skip down to Step 12.
Step 11: Remove the fender liner
There are a bunch of TORX20 bolts holding the fender liner in. Once its loose, remove it from the car. You will now see something like this.
Get a bucket handy as you will want have something to drain the washer fluid back into. Slide the left side reservoir out and disconnect it from the quick connect nozzle as shown below.
You now have easy access to the three 10mm bolts. Its much easier this way. It is also much helpful doing it this way when reinstalling the bumper.
Step 12: Remove Fog Light Surrounds
Once your done, its time to remove the fog light surrounds. Grab a flat head screw driver. You will notice the screw is vertical. Twist the screw to the horizontal position as shown below and it will pop free. Remove it from the car.
Step 13: Remove Bumper bolts
The bumper is almost ready to come out. There are two HEX bolts holding the bumper on located where the fog light surrounds were. Grab your 3/8 ratchet and HEX6 socket. Loosen them but do not remove them. A picture is shown below where they are located.
Step 14: Remove Bumper
The bumper can now be removed from the front end of the car. There are two connectors on the drivers side that need to be disconnected in order to move the bumper away from the car.
Step 15: Remove AUX Radiator Shrouds
Once the bumper is placed to the side we can start working on the RAD support. There are two radiator shrouds that must come out on each side of the front end in front of the AUX radiators. Grab your 10mm socket and remove these bolts. Repeat on Drivers side.
Step 16: Remove Upper Rad Support Bolts
Okay now the upper rad support bolts can come out. Grab your TORX30 socket and remove both bolts. Repeat on the drivers side.
Dont put your TORX30 down, there is another bolt down by where the AUX rad shrouds were. Remove it. Repeat on drivers side.
Step 17: Remove Main Rad Support Bolts
Grab your Torx45. Its time to take out the RAD support bolts. There are three on each side. You might need a breaker bar to get them loose. Repeat on drivers side.
Step 18: Slide Radiator Forward
Once the six RAD bolts are out, you can now slide the Radiator forward. You should make a gap around 3 or 4 inches as shown below. If needed, place a bucket under the RAD to support it.
Step 19: Removing the Belt
Okay. Here is where you will need two people. Grab your torque wrench and put a 18 mm socket on it. Also grab your 3/8 ratchet and put a 13mm socket on it. First, loosen the 13mm bolt on the bottom as shown, but do not remove it.
Once it is loose, grab your torque wrench and put your socket on the adjustment bolt head shown below.
IMPORTANT: In order to loosen the belt you need to go CLOCKWISE (Tighten) on this bolt head. Once you do that the belt will pop loose.
Step 20: Install new belt.
Pay attention to how the belt is run before you pull it off. Once its off, install the new belt in the same fashion. Audi rings should be facing the drivers side. He is a picture if you forget how it went.
Step 21: Tighten New Belt
Once the belt is run, have a friend get the 18mm socket back on the adjustment bolt head and go COUNTER-CLOCKWISE to 70nm. Once its tightened, take your 13mm socket and tighten the 13mm bolt to 20nm (hand tight).
That's it, the belt is now installed! You now can follow this DIY in the reverse and reassemble the car. While your here this would be a good time to put an aftermarket snub mount on.
I hope this helps everyone. Good luck! Please feel free to contact me if you have any questions.
