Cars Specification

1. Remove the spark plugs with a socket wrench, and disconnect the valve covers.
2. Clamp the timing chain to the camshaft gear. Plug the opening in the cover for the timing chain with shop rags. Attach a chain-breaker to the master link on the timing chain. Separate the master link by using the chain-breaker. Release the clamp from the camshaft gear, and remove the shop rags from the hole in the timing chain cover.
3. Attach the master link on the new timing chain to the master link on the old timing chain. Turn the crankshaft clockwise with a socket wrench as you pull the old timing chain through the camshaft sprocket. Maintain tension on the old timing chain, and stop turning when the master link on the old chain is in the 12 oclock position on the camshaft sprocket.
4. Disconnect the master link on the old timing chain from the master link on the new timing chain, and remove the old timing chain from the camshaft sprocket. Connect the free end of the master link on the new timing chain with the other free end of the timing chain. Make this connection from the rear of the camshaft sprocket, so that you can see the lock washers on the timing chain.
5. Turn the crankshaft clockwise to align the timing mark on the crankshaft with the timing mark on the crankcase. This will close the master link on the new timing chain. Turn the crankshaft at least one full turn clockwise to ensure the new timing chain is properly seated.

1. Park the Audi on level ground.
2. Lift the front portion of the Audi using a jack and rest it on axle stands.
3. Remove the two screws from the wheel wells and the six screws from the Audis underpan by turning a screwdriver counterclockwise.
4. Take off the two lower grilles and the bolts found near the Audis fog lights by turning an Allen wrench counterclockwise.
5. Grab and remove the Audis headlight washer hose, found by the drivers side lower grille. Put a bucket under the Audis front bumper to collect any fluid that will drain out.
6. Jerk the front bumper from the Audi in an upward, then downward motion to remove it. Grab and take off the horn and headlight wiring and turn signal bulbs on either side of the Audis front end.
7. Remove all three drivers side headlight screws and the four passengers side headlight screws found under the headlights by turning a T45 Torx screwdriver counterclockwise.
8. Take off the two screws found above the headlights and the two screws found at the sides of the headlights by turning a T30 Torx screwdriver counterclockwise.
9. Grab and take off the lock carrier from the Audis fan, as well as the wiring and timing belt cover, then unscrew all four bolts from the fan by turning an Allen wrench counterclockwise. Slide the fan away from the Audi.
10. Loosen the two A/C compressor bolts to take off the A/C compressor belt and jerk the spring-loaded tensioner found by the fan using a crescent wrench to reveal and remove the Audis serpentine belt.
11. Take off the damper pulley from below the Audis fan by unscrewing its four bolts counterclockwise using a metric wrench. Hold the damper pulley with a breaker bar. Remove the lower timing belt cover by unscrewing its three bolts.
12. Turn the damper pulley crank clockwise to line up the cam sprocket and valve cover with their marked sides. Then unscrew the three bolts that hold in the tensioner and the bolt that holds in the guide pulley. Install a new tensioner to the guide pulley. A tensioner and a new timing belt can be purchased with a timing belt kit from most auto parts shops.
13. Unscrew the guide pulleys bolt from its brass-colored portion, take off the timing belt, then place a new timing belt at the Audis sprockets. Assemble the guide pulley with an Allen wrench, then take out the new tensioners pin using your fingers.
14. Install all of the Audis components back in their places by performing these steps in reverse. Remove the axle stands from the Audi to lower the vehicle.
