1. Drive the car somewhere out of the way, or tow it if the wastegate is broken. Driving a turbocharged car with a damaged wastegate can seriously damage the turbocharger and the engine. Place the car in park and turn off the car. Pull the hood release latch and then prop the hood up with the prop stick. Disconnect the black wire from the car battery to ensure that the cars circuits are dead.
2. Locate the wastegate valve on the turbine side of the turbocharger. The wastegate is a small metal valve bolted onto the turbochargers exhaust feeder pipes. Disconnect the control wire from the wastegate and place it to the side. Use a wrench to unbolt the two bolts that secure the old wastegate to the turbocharger. Pull the wastegate out, being careful not to scrape the sides of the hole.
3. Slide the new wastegate into the hole on the exhaust feeder pipe. Slide in the bolts and screw them down by hand. Once both bolts are down, wrench them down flush with a wrench. Plug in the control wire into the side of the wastegate. Make sure there is no packing material stuck in the valve. Reconnect the black wire on the car battery and then shut the hood. Turn on the car and take it for a test drive.

1. Lift the wiper arm and wiper off the windshield. Pushing the small retaining clip, remove the wiper blade assembly from the arm. If you are having trouble releasing the clips, use a small blade screwdriver as a pry. Gently return the arm back to the windshield.
2. Locate and release the retaining clip or pin that holds the insert onto the blade frame assembly. If there is no retaining clip, use a pair of needle nose pliers to gently bend the retaining point up so the insert can slide out. Slide the insert with the two metal shafts on either side off the blade frame.
3. Install the new insert with the metal shafts on both sides by sliding one end into the first blade frame retaining point. Slowly guide the insert and metal shafts into all of the retaining points until it is fully inserted into all of the blade insert holders. There may be 6 or more blade insert holders.
4. Reattach the retaining clip or bend the retaining point back. Check that the insert will not slide out of the wiper blade assembly.
5. Pick up the wiper arm from the windshield and position the wiper blade assembly on the shaft of the arm. Push with steady pressure until it snaps into place. Gently return the wiper blade and arm to the windshield.

1. Open your hood and locate the air filter box and intake tube. Turbo models will feature a heftier intake that attaches to the turbocharger, while naturally aspirated engines have intake that attaches to only the throttle body.
2. Disconnect the electrical wiring, hoses and mass air flow meter that attach to the factory intake tube and set aside for use with the new intake system. Unfasten the hardware that holds the intake tube in place and remove slowly, careful not to spill any debris. If necessary, use a flat-head screwdriver to assist you in removing the intake tube.
3. Unscrew the bolts that hold the stock air filter box into place. Remove this factory intake box completely and dispose of it properly, as you will not need the filter or its housing box for the new install.
4. Check the new intake tube and count the number of holes that are drilled into the side. If there are more holes than hoses that attached to the old setup, plug the unnecessary holes with the grommets that came with your intake kit.
5. Attach the new intake tube to your A4 directly as the old one was removed. This part will mimic the old intake tube in design and functionality, while the filter itself will be positioned differently and provide better performance. Secure the intake tube with the silicone coupling that came with your cold air intake kit. There should also be a clamp ring that came with your kit to hold the silicone coupling and intake tube into place.
6. Attach the downward piece of the intake tubing system to the newly installed tube from Step 5. By this point, the intake tube should extend to the front of the engine bay and underneath the front of the car. The cold air will come in through the bottom of the front side of the vehicle, increasing horespower and fuel efficiency in your Audi A4.
7. Spray down the new air filter with the necessary lubricant before installing. Position the cone air filter that was provided in the cold air intake kit onto the downward intake tube. Tighten the clamp fitted around the cone filter to secure into place. Reconnect any remaining hoses and wiring that were removed at this time.

1. Insert a flathead screwdriver into the farthest corner of the passenger side front grille and pry down on the tab that sits on the opposite side.
2. Pull the opposite corner of the passenger side grille piece out while pushing down on the tab with your flathead screwdriver. Pull the plastic grille piece out to remove it.
3. Insert your hand through the opening where the passenger side grille was installed and grasp one of the fasteners that are installed along the inside perimeter of the center grille insert.
4. Push the center grille insert out of the bumper by pressing down on the fasteners on the inside perimeter and pushing the plastic piece outward.
5. Insert the flathead screwdriver into the upper right or left corner of the drivers side grille insert and pry the plastic piece out of the bumper.
6. Position the new grille inserts into the bumper and install each by pressing the corners into the bumper so that the grille pieces snap into place. Press down along the circumference of the grille inserts to finish the installation and ensure that each piece is secured.
