1. Turn off the A4. Ensure that the parking brake is on and that the gear selector is in Park.
2. Open the trunk by either pulling on the trunk release button beneath the steering wheel or by pressing the trunk release button on your key fob if you have that option.
3. Locate the oval panel on the side of the trunk wall. Pry the panel off with a flathead screwdriver, using gentle pressure to avoid cracking the plastic of the trunk. There will be a bolt head inside the cavity that was covered by the plastic panel.
4. Loosen the bolt inside the cavity. This will release the lens cover on the brake light on the rear of your Audi. Be prepared to catch the lens, to prevent scratching the lens or the rear paint. If the lens cover does not come off on its own, you can pry it off gently with a flathead screwdriver. Be gentle to avoid damaging the paint or cracking the lens.
5. Remove the light bulb from the electrical harness by hand. The bulb just plugs into the port--no special tools are necessary. Place the lens cover back on the tail light. While holding the lens up, thread the bolt back into the cavity by hand until it catches in the grooves on the lens backing. Tighten the lens down with a wrench, until the lens cover will no longer wiggle if you push on it.
6. Repeat this process for the other tail light. Turn the car back on and test the brake lights by pressing down on the brakes while someone else looks for the brake lights to signal.

1. Jack up on the front of your Audi A4 under the front jack point behind the radiator, using the floor jack.
2. Place jack stands under the front pinch welds of the vehicle and lower the Audi onto the stands.
3. Climb under the vehicle and disconnect the electrical connector from the oxygen sensor.
4. Unbolt the oxygen sensor from the exhaust using an O2 sensor socket and socket wrench.
5. Remove the sensor and thread the new sensor into the exhaust. Tighten the sensor using a socket wrench and O2 sensor socket.
6. Reconnect the electrical leads to the sensor.
7. Lower the A4 to the ground using the floor jack.

1. Add the oil-based dye, supplied in the kit, to the power steering reservoir. The reservoir for the Audi A4 is located on the drivers side inner fender well, just in front of the windshield reservoir. Test-drive the vehicle for 10 minutes to circulate the dye and load the power steering system. This will force small leaks to show up.
2. Use the black light, supplied in the kit, to search under the hood for leaks. Start at the power steering reservoir, following both the small return hose and the larger supply hose to the power steering pump and the rack and pinion steering gear. Note any leaks found.
3. Raise and support the vehicle using the floor jack and jack stands. Then, from underneath, inspect the power steering rack and the power steering hoses. Note any leaks found.

1. Position the car ramps behind the vehicle and back up onto the ramps slowly. Place the tire stops in position behind the front tires to secure the vehicle from moving during the replacement.
2. Lift the vehicles hood and locate the fuse panel. Remove the bolt securing the panel using the crescent wrench. Remove the fuse responsible for controlling the fuel pump.
3. Find the fuel filter under the rear of the vehicle near the fuel tank. Position the floor jack below the fuel tank in preparation of lowering the tank. You will only be lowering the fuel tank about four inches. Using the crescent wrench, remove both metal holding straps that secure the fuel tank in place.
4. Using the floor jack, lower the fuel tank about 4 to 6 inches to gain full access to the fuel filter. Use the crescent wrench to remove both fuel lines going into the fuel filter. Remove the securing bolt and remove the old fuel filter.
5. Install the new filter and replace the securing bolt. Reattach both fuel lines ensuring the arrows on the filter are pointing toward the front of the vehicle. Using the floor jack, lift the fuel tank back in place and reattach the metal holding straps.
6. Reinstall the fuel pump fuse and reattach the bolt that secures the fuse panel. Remove the tire stops and start the vehicle. Drive the vehicle off the car ramps.
