1. Choose which vent you are going to install the gauge in and remove it by pulling it out. Inspect the vent to see if the gauge will fit into it. You may have to trim the rear flap of the vent to allow the gauge to sit in it.
2. Hold the boost gauge against the vent and draw a circle with a pen or white pencil around it to mark where the cut is going to go.
3. Use a dremel with a small cutting wheel and carefully trim the hole that you have traced. Test fit the gauge to make sure it fits in the trimmed hole very snugly. Smooth any rough edges with sandpaper.
4. Drill a small hole in the ducting that leads to the vent to allow the pressure tube for the gauge to go through. Run the tube through it. This should be included with the gauge.
5. Remove the trim located below the steering wheel and remove it. There are probably three or four 8-mm nuts.
6. Open the hood. At the rear of the engine on the left side of the brake fluid reservoir are two rubber seals. Remove them both, exposing two holes.
7. From under the steering column, route the gauge tube through the holes. Make small holes in the rubber seals for the tube. Run the tube through the seals and then reinstall the seals.
8. Connect the gauge to the intake manifold by cutting the hose that goes to the fuel pressure regulator and installing a T adapter for the gauge hose.
9. Hook up the power wire for the gauge to an existing wiring harness that goes to the factory gauges. Ground the black wire that is on the gauge to a suitable ground in the dash. Reinstall the vent and gauge and test it to make sure it works.

1. Disconnect the battery cable that goes to the negative terminal on the battery. Loosen the hose clamp that holds the mass air flow sensor tubing to the air box.
2. Unplug the harness for the mass air flow sensor. Remove the bolts that hold the air box onto the engine. The number and size of bolts will vary, depending on the model. Set the air box aside.
3. Remove the cold air snorkel in the center-front of the engine by carefully prying the plastic rivets up and then pulling the snorkel off.
4. Loosen the belt tensioner with a socket and ratchet until the belt is loose. Slide the belt off the pulley for the alternator. Disconnect the wires that go to the back of the alternator, noting where they go, for later reassembly.
5. For added clearance, remove the two bolts that hold the power steering reservoir on and set the reservoir out of the way. Remove the upper and lower alternator mounting bolts that bolt the alternator in place. Remove the alternator. You may need to use a pry bar or the tap the alternator to loosen it from the bracket.
6. Install the pulley from the old alternator on the new alternator, if it does not have one. Reinstall the alternator and tighten the two bolts. Plug the alternator back in. Install the belt and tighten the belt tensioner.
7. Reinstall the power steering pump reservoir. Reinstall the cold air snorkel and the air box. Reconnect the wire for the MAF and the battery cable.

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.
