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. Park the vehicle on a flat surface.
2. If the engine has been running, allow it too cool completely.

1. Park the 1998 Audi A6 in a safe and level work environment. Set the emergency brake.
2. Jack up the front of the 1998 Audi A6 and put the jack stands under the designated front jacking points on both sides of the car. Then, lower the Audi onto the jack stands. Pull the jack out.
3. Move the jack to the rear of the Audi and jack it up in the air. Place the jack stands under the designated rear jacking points on both sides of the Audi. Then lower the car onto the jack stands. The whole car has to be on jack stands so that you will be able to get an accurate transmission fluid reading.
4. Crawl under the driver side of the Audi near the driver side door. Locate the transmission pan on the bottom of the transmission. Then, locate the transmission fluid fill plug on the very front of the transmission pan.
5. Slide the fluid catch pan under the transmission fluid fill plug on the front of the transmission pan. Then, remove the fill plug with the 1/2 inch drive ratchet and socket by turning the fill plug counter clockwise. Pull the fill plug out of the pan.
6. Crank the engine and let it run for about two minutes to heat up the transmission fluid. Keep the engine running while checking the transmission fluid level.
7. Stick you finger inside the fill hole and locate the fluid level. The transmission fluid should be either coming out of the fill hole when you remove the fill plug or the fluid level should be at or near the plug hole with the engine running.
8. Put the fill plug back into the pan and tighten down with the ratchet and socket. Remove the fluid catch pan from under the car. Turn the engine off and reverse the steps for jacking up the Audi to remove the jack stands.

1. Lift the vehicle with a floor jack and place a jack stand under the front and back axles behind each wheel. Verify that the vehicle is level when on the jack stands.
2. Locate the drain plug on the bottom of the transmission pan and place a drain pan on the ground under the plug. Remove the drain plug with a socket wrench, allowing the transmission fluid to drain completely.
3. Remove the bolts on the transmission pan with a socket wrench and set the bolts in a safe place. Remove the transmission pan, using a screwdriver to carefully pry the pan off the transmission.
4. Clean out any debris and sediment from the inside of the transmission pan with clean paper towels. Unbolt the white plastic transmission filter from underneath the transmission with a socket wrench and dispose of the filter.
5. Remove any debris and oil from the bottom of the transmission where the filter attaches, with a clean cloth. Place the new filter gasket between the bottom of the transmission housing and the transmission filter and attach the new transmission filter to the bottom of the transmission.
6. Scrape the remaining gasket material off the bottom of the transmission and off the transmission pan with a putty knife. Place the new rubber transmission pan gasket around the lip of the transmission pan.
7. Attach the transmission pan to the bottom of the transmission and secure it with bolts. Screw the drain plug into the bottom of the transmission pan by hand until it is snug and tighten the drain plug with a socket wrench just enough so it is secure.
8. Unscrew the fill plug on the side of the transmission fluid oil pan with a socket wrench. Refill the transmission oil pan with transmission fluid, using a high output pump, until the fluid is running out of the pan.
9. Install the oil fill plug of the Audi automatic transmission pan and tighten by hand. Turn the engine on and place your foot on the brake pedal. Shift the transmission into each gear for about ten seconds to run the fluid through the transmission.
10. Put the transmission back into park and let the engine idle. Remove the oil fill plug on the side of the transmission pan by hand and fill the pan with fluid using the high output pump until the fluid runs out of the fill hole.
11. Place the drain plug into the side of the drain pan, securing it with the socket wrench. Shut off the vehicle engine.
12. Lift the vehicle up with a floor jack to remove all the jack stands and set the vehicle back down on the ground. Dispose of the drained transmission fluid at the local recyclers or automotive center.

1. Notice if there is red fluid leaking from your Audi and onto the ground. If so, you most likely have a transmission fluid leak.
2. Set up ramps in front of your Audi and drive up the ramps. Engage the parking brake and put a wood block behind a rear tire. Turn off your Audi and let it cool down.
3. Look underneath your Audi using a flashlight. Find the transmission located behind the engine. Inspect the transmission for loose wiring harnesses or broken shift linkages. These problems may be the cause behind your Audis transmission problems.
4. Restart your Audi, allowing the transmission to run warm. The best time to check the transmissions fluid level is when the vehicle is still running.
5. Pop the hood and locate the transmission dipstick. You can find it on the drivers side of the engine compartment. It has a label reading transmission. Pull the dipstick out and wipe it clean with a cloth. Slide it in the tube and pull it out, reading the fluid level. If the level of fluid in the transmission gets too low, the transmission will fail.
6. Smell the transmission fluid; if you detect odor and the fluid is very dark in color, it should be replaced. Transmission fluid that is burnt or dirty can make the transmission fail.
