Car Performance Specs

1. Place the BMW’s transmission into Park (automatic) or neutral (manual transmission) and apply the parking brake. Leave the engine running.
2. Connect a scan tool to the BMW’s diagnostic data port, which is under the dashboard just above the pedals on the driver’s side.
3. Power on the scan tool and choose “Bi-Directional Tests” from the main menu. Select “IAC Valve Actuation” from the tests menu.
4. Use the scan tool’s buttons to open and close the IAC valve. The idle speed should rise and lower without pressing the accelerator. If the IAC valve does not respond to the scan tool by raising and lowering the engine idle speed, then it is faulty.

1. Disconnect the negative terminal on the battery. Ensure that you have the code for your radio if it is the OEM stereo, since disconnecting the battery resets it.
2. Remove the Torx screws that hold the instrument cluster to the dash pod with a T20 Torx bit and a ratchet.
3. Protect the plastic on the gauge panel with a piece of flannel. Also lay a heavy towel on the steering column to offer more protection.
4. Slide a very thin tool (feeler gauge, thin spatula, etc.) between the cluster and the gauge pod on the edge near the center of the car. Very gently pry the cluster out far enough so that you can access the wires on the back of it.
5. Disconnect the three electrical connectors that go to the back of the cluster. The connectors are released by pressing the tabs down where they connect and pulling the wires out. Move the cluster to your workbench and lay it on a soft towel.
6. Replace the two odometer bulbs by turning and pulling them out of the instrument cluster and installing the new ones. Use a small screwdriver to help twist in the new bulbs. The odometer bulbs are beige. All of the other bulbs are black.
7. Place the instrument cluster back in the dash pod and connect the three electrical connectors. Carefully slide the cluster back into place and tighten the two Torx bits. Enter the radio code if needed and reset the clock.

1. Place a floor jack under the transmission cross member and jack the front of the Audi off the ground. Place a jack stand on each A-Arm and lower the vehicle onto the jack stands. Make sure the emergency brake is in place or a wheel chuck is placed behind the rear tires to prevent the vehicle from rolling backwards while you work on it.
2. Place a drain pan under the petcock of the radiator and drain the radiator fluid into the pan. Depending on the age of the Audi, the petcock may be hard to open due to exposure to road dirt and salt over the years. Use a pair of pliers but be cautious as the valve easily breaks if excessive force is used. Once the fluid drained, close the petcock.
3. Trace the lower radiator hose from the radiator to the location where the hose connects to the engine. The location is to the right of the engine crank and may be difficult to see from under the vehicle. Depending on your comfort level, you may want to complete the rest of the job from the top of the engine, not the bottom.
4. Remove the radiator hose from the thermostat cover by squeezing the two metal tabs located together on the retention band clamp. A pair of needle-nose pliers is suggested for this task. With the tabs squeezed together, pull the radiator hose off the cover.
5. Remove the two bolts that secure the cover to the engine block with a boxed-end wrench. Unfortunately, there is not enough room for a ratchet. To remove the bolts, make short quarter turns of the wrench, as that is all that is possible in the limited space. With the bolts removed, pull the cover off the engine block.
6. Remove the gasket O-ring that fits into the bottom of the thermostat cover. If the cover does not have an O-ring, inspect the engine block for it. It sometimes sticks to the engine block.
7. Pull the thermostat out of the engine block. Take note that the end with the pin sticks out of the engine block. Place the new thermostat into the engine block so it sticks out in the same manner.
8. Place the thermostat cover back over the thermostat and thread the bolts in as far as you can with your fingers. Tighten the bolts with a boxed wrench.
9. Reattach the lower radiator hose to the thermostat cover. It helps to slide the clamp backwards on the hose and then push the hose onto the cover without the clamp. Then use the pliers to squeeze the tabs and slide the clamp into place.
10. Fill the radiator with a 50/50 mix of radiator fluid and distilled water.

1. Loosen the lug nuts on both front wheels by turning them 1/4 turn counterclockwise.
2. Raise the BMW up using the floor jack. Jack under the front jack point.
3. Place jack stands underneath the pinch welds of the BMW and lower the vehicle onto the jack stands.
4. Finish loosening the lug nuts and take the wheel off.
5. Unbolt the top and bottom brake caliper mounting bolts on the BMW and secure the caliper to the coil spring above the brake assembly with the zip ties.
6. Remove the brake pads by taping them out with a rubber mallet.
7. Place the face of the brake pad over the caliper piston and then place the c-clamp over the back of the brake pad and caliper assembly. Gently force the caliper piston back into the caliper by tightening the c-clamp.
8. Insert the new pads and reassemble the brake system. Installation is the reverse of removal.
9. Repeat steps 4 - 8 with the other front wheel.
10. Put the wheels back on, tighten the lug nuts and lower the vehicle. Torque the lug nuts to 100 foot-lbs once the wheel is back on the ground.
11. Raise the rear of the BMW using the rear jack point and place the jack stands under the pinch welds in the rear of the vehicle.
12. Lower the vehicle onto the jack stands and then repeat steps 4 - 8 for the rear wheels.
13. Put the wheels back on, tighten the lug nuts, and lower the rear of the vehicle. Then, tighten the lug nuts to 100 foot-lbs.

1. Above the radio, locate the symbol or drawing on the button that resembles a windshield. Once you have located the button push it and it should illuminate. In models from the early 90s to 1999 there will be a knob. In the 2000-2008 models, there will be a button.
2. Once you push the button, you have activated the windshield defrost option. In models from the early 90s to 1999 you will have a knob. In this case point the line on the knob towards the symbol of the windshield.
3. Once you do this, find the dial that shows the temperature of the desired air flow. With this feature, you can control the desired temperature, whether you need warm or cold air to blow on the windshield.
4. Locate the button or knob that is used to control the level of the airflow. Again, this will depend on the year of BMW. Adjust the level of airflow that you desire. You will see any fog on the window start to dissipate rapidly. If it does not start to evaporate, try using the opposite temperature that is blowing.
5. Turn the dial to the color blue which represents cold air. Any fog that is on the window should evaporate. If the problem persists, spin the dial to red. This will make warm air flow through the vents, and should solve the problem
6. problem.

1. Turn the C230s headlight switch to 0. Turn off the engine and open the hood. Inspect the area behind the front lighting case. Find the black front marker lamp access cover. It is the outboard cover, closest to the fender on either side.
2. Grasp the access cover handle and turn it counterclockwise to unscrew the cover. Attached to the other side of the cover, youll find the front marker lamp. The cover doubles as the socket.
3. Pull the lamp straight out of its socket. Put on clean gloves and open the replacement lamp package. Insert it straight into the socket.
4. Attach the access cover/socket back against the rear side of the lighting case. Turn the cover clockwise to reattach it to the case. Close the cars hood.

1. Connect a OBDII-type engine code reader to your car using the connection port underneath the steering wheel area. Turn the ignition to the on position but do not start the engine. Let the code reader connect with the car computer to see if it will generate a code for a faulty mass air flow sensor. Confirm whether the sensor is actually triggering a malfunction code or not. Erase the code stored in the computer using the reader tools. Turn the car off and disconnect the code reader.
2. Raise the hood and locate the air filter box. Open the air filter box and pull out the old air filter. Use a shop vacuum to suck up all the debris, dust and dirt inside the filter box. However, do not poke the vacuum into the cavity going to the mass air flow sensor.
3. Turn off the vacuum and use a screwdriver to disconnect the hose clamp holding the intake hose to the bottom of the mass air flow sensor going toward the engine. Pull the hose off and place it clear of the sensor. Carefully disconnect the wiring to the mass air flow sensor itself. Use the screwdriver to carefully push the connection tab free if the wiring junction uses a snap-lock to connect. Place it safely clear of the sensor unit.
4. Use a screwdriver with a star-shape, or security Torx bit if the sensor is secured to the air filter box with screws having star-shape heads. Use a regular screwdriver if the screws are Phillips-head or flat-head style. Carefully loosen and remove the sensor screws and put them in a safe place to avoid losing them. Use the shop rag to carefully twist the sensor back and forth by hand until it comes free from the air filter box.
5. Move the sensor unit to a clear workspace. Put a shop rag underneath it and do not touch the sensor mechanism inside. Attach the spray nozzle to your bottle of mass air flow sensor cleaner and spray the sensor clean with five or six good sprays. Spray downward so the excess hits the rag underneath. Examine the wire inside without touching it to confirm it is clean. Let the unit air dry on the rag for 30 minutes.
6. Reattach the sensor, without touching the inside wire mechanism, to the air filter box and following the above removal steps in reverse order. Install a new air filter in the air filter box and close it up. Confirm you reconnected the sensor wiring, re-installed the sensors screws, reattach the air hoses and re-tightened the hose clamps. Check for missing tools as well. Close the hood and restart the car. Let the engine warm up and drive it to check if the sensor gives off a trouble code again. Replace the sensor unit completely if it does.

1. Sand the Mercedes with 330-grit sandpaper to smooth the surface and remove the top layer of the clear coat paint. This step also removes any light scratches or nicks in the paint. Hold the sandpaper flat against the surface while sanding.
2. Use the 600-, 900- and then 1200-grit sandpaper on the surface of the Mercedes with water. Sand the entire vehicle with the lowest grade, then sand it again using the 900- and then 1200-grit paper. Keep all of the sandpaper soaking wet while sanding to prevent the buildup from scratching the surface. Using the different levels of sandpaper ensures the surface is smooth and free of scratches. Rinse the car and allow it to dry completely.
3. Cover any areas that wont be painted using masking tape and paper. Cover the tires and wheels, window glass, trim, mirrors and door handles so paint doesnt cover them. Wipe the surface with wax and grease remover and a towel. This evaporates quickly and doesnt need to be cleaned off.
4. Spray three to five thin coats of paint onto the surface of the Mercedes. The thick layers of original primer and paint already on the Mercedes allow the new paint to be applied in thin layers with full coverage. Hold the sprayer 6 to 8 inches from the surface and use left and right strokes.
5. Apply three coats of clear coat paint on top of the new paint on the Mercedes. Wait a full 24 hours before handling the surface of the car.

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.
