Car 2013

1. Insert the key into the ignition and turn it to the first position. This is where the ignition comes on, but the engine does not start. The lights on the dash should illuminate and the FSS display will turn on.
2. Press the R button twice. This is the button located directly beneath the FSS display, which is also marked mileage. The number of days and miles remaining on the current service interval will show on the screen.
3. Turn the key back to the off position. Then, hold down the R button and turn the key back to the same position. Continue holding the button until a beeping sound is heard. The system has now been reset and you may release the button.

1. Open the hood and examine the area behind the headlights or front turn signals. You should see where the wires go into the back of the bulbs.
2. Remove the cover for the headlight housing, if there is one. This will be held on either with snaps or a couple of Phillips-head screws.
3. On some models, such as the A4, you must remove the air intake duct on the passenger side to gain access to the bulb. This is held on with two Torx screws on top of the duct.
4. Remove the two or three screws that hold the top of the headlight housing in place. Loosen--but do not remove--the screws that hold the bottom into place.
5. Gently push the headlight forward to gain access to the bulbs.
6. Unclip the wire clip that holds the bulb into the housing, and pull out the bulb and harness.
7. Install the new bulb in the reverse of removal.
8. Open the trunk (on a sedan) or the hatch (on a wagon), and inspect the area behind the taillights and rear turn-signal housings. There will be a small, round plug in the back of the housing that conceals the screw for the housing.
9. Pry the housing cover out with a thin screwdriver, and remove the screw.
10. Pull the taillight housing away from the body of the car. You may have to move some of the rubber seal that goes over the housing to be able to pull it out.
11. Separate the panel that holds the bulbs from the back of the housing.
12. Press down gently on the bulb, and turn the bulb to release it.
13. Install the new bulb and replace the pieces in the reverse of removal.

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. Remove the two bolts that secure the water outlet housing to the Audis engine with a socket and ratchet. With the bolts removed, lift the housing off the engine to expose the thermostat.
2. Note the positioning of the thermostat inside the engine. When you replace the thermostat, you must install it with the same positioning. Pull the old thermostat out of the engine and plug the hole with a shop rag.
3. Remove the old gasket from the engine with a wire brush or metal scraper. Do the same for the old gasket material stuck to the bottom of the water outlet housing.
4. Pull out the shop rag from the engine and install the new thermostat into position. Place a new gasket over the thermostat.
5. Place the water outlet housing onto the gasket and secure both to the engine with the socket and ratchet.

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. Upgrade the A6 engine to 5.2-liter V-10 levels of performance, 435 horsepower at 6,800 rpm and 398 ft-lb of torque at 3,000 rpm. As previously mentioned, sourcing an Audi V-10 is near impossible as they are not sold as crate engines, so the only feasible path for an engine swap is to buy it secondhand, which is also near impossible given the rarity of S6s in America. Europe and now China, have the greatest number but after shipping, the cost can be as much as the A6 itself. Realistically the only way is to upgrade is to flash the Engine Control Unit (ECU) to S6 levels of performance, though this will also require upgrades to the air-intake and exhaust.
2. Flash the ECU with upgraded software; this is available from a number of vendors. To reach 435 hp the engine will need to be turbocharged and the exhaust replaced. Flashing the ECU is the easiest with most options just involving hooking up a software module to the diagnostic port though some must be hardwired into the ECU itself. If the flasher needs to be soldered on then an auto repair shop should install it given the danger of permanent damage.
3. Turbocharge the engine; preferably with the turbochargers that are used on the Audi RS6 but there are universal turbochargers that will give similar levels of performance, these just take longer to install. The highest level of the 6 platform is the RS6 which uses the same V-8 engine as the A6, but turbocharged. These turbochargers are somewhat easier to find but there are also third-party vendors that offer turbochargers as well. This installation should be done by a professional auto shop, preferably one that specializes in high-end European imports.
4. Upgrade the exhaust; if possible use the exhaust off the S6 or RS6 but there are many vendors that supply exhaust systems for the A6. Borla and Remus are the most popular options and again require an auto shop to complete as the header work alone can take a week.
5. Swap badges; Audi tends to be less prolific than other car companies in their love of badges however they still need to be replaced if the transformation is to be complete. The real badges are expensive and somewhat rare, however there are fake badges that are mirror images and cannot be told apart exceptt by an Audi technician. The S6 badges are needed on the outside and the S6 speedometer facing will need to be placed.

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.

3. Leave your car and hold your remote near the right headlight.
4. Press the open button on your remote and hold it until the hazard lights blink three times.
5. Press and hold the HomeLink training button inside of the car until the indicator light glows solid. If the light does not turn solid, continue to the following steps.
6. Press and hold the smart button on your garage motor, located on the side or back near the antenna wire.
7. Press the train button on your Audi system within 30 seconds of pressing the smart button and wait for the indicator light to glow solid. The programming will now be complete and your remote will be ready to use.
