How to Number the Injectors on a BMW 740i


1. Walk around the front of your BMW and open the hood.
2. Locate the fuel injectors on top of the engine. You will see one injector per cylinder--four injectors on the left and four on the right.
3. Grab a piece of paper and pencil and write down the numbers 4, 3, 2, and 1 on a single column to the left of the paper. Make sure there is some space on top and bottom of this column.
4. Write down the numbers 8, 7, 6, and 5 on a single column to the right of the first column of numbers.
5. Write down the word rear on top of the two columns of numbers, and the word front at the bottom of the two columns of numbers.
6. Grab your piece of paper with the two columns of numbers and stand in front of the engine, facing the drive belt. If you look at your notes on the piece of paper, the two columns of numbers represent the cylinder numbers in your BMW 740i. The word rear represents the back of the engine and the front represents the front of the engine, which you are facing right now.
7. Label each of the fuel injectors using a piece of masking tape and a black marker, according to the numbers you have assigned to the each cylinder.

How to Install a Wastegate on a Turbo


1. Drive the car somewhere out of the way, or tow it if the wastegate is broken. Driving a turbocharged car with a damaged wastegate can seriously damage the turbocharger and the engine. Place the car in park and turn off the car. Pull the hood release latch and then prop the hood up with the prop stick. Disconnect the black wire from the car battery to ensure that the cars circuits are dead.
2. Locate the wastegate valve on the turbine side of the turbocharger. The wastegate is a small metal valve bolted onto the turbochargers exhaust feeder pipes. Disconnect the control wire from the wastegate and place it to the side. Use a wrench to unbolt the two bolts that secure the old wastegate to the turbocharger. Pull the wastegate out, being careful not to scrape the sides of the hole.
3. Slide the new wastegate into the hole on the exhaust feeder pipe. Slide in the bolts and screw them down by hand. Once both bolts are down, wrench them down flush with a wrench. Plug in the control wire into the side of the wastegate. Make sure there is no packing material stuck in the valve. Reconnect the black wire on the car battery and then shut the hood. Turn on the car and take it for a test drive.

How to Add an iPod to a BMW 745i


1. Acquire a cassette tape adapter (if the vehicle has a tape player in it, as many older BMW models do). You can purchase this handy little device for around $20 at most electronics, audio or department stores. Simply insert the plug into the headphone jack and put the tape into the tape player to transport the sound from the iPod through the tape deck and subsequently out of the BMWs speakers.
2. Purchase an FM transmitter. This small broadcaster plugs into the iPod and transmits the audio within a small radius, allowing the antenna on the vehicle to receive it and play it on an empty FM radio station. (An empty station has either complete, or nearly complete, static; this means no radio stations are broadcasting locally on that particular frequency, making it open for FM transmitters to use.)
3. Have an auxiliary cable wired into the BMWs stereo by a car audio specialist. This small cable will run from the internal guts of the stereo into the cabin of the vehicle, allowing you to insert it into the headphone jack of the iPod and play it through the stereos auxiliary input.
4. Bring the vehicle to a car audio specialist and ask to have an iPod integration dock installed. This option will prove the most, but some car stereos allow you to plug a small adapter into the data dock on the iPod and use a digital display on the stereo to cycle through the iPods menu and operate it in almost the same way as if you were holding the iPod in your hand. (Note that this option may require a full replacement of the BMWs stereo.)

How to Check a Motor Mount


1.
A powerful flashlight will help to locate motor mounts in difficult-to-see areas.
Block the wheels with the wheel chocks to prevent movement of the vehicle either forward or backward. Raise the hood of the vehicle and use the flashlight to locate the motor mounts. Motor mounts will be located in various locations above and below the engine and transmission depending on the specific model.
2. Examine the motor mounts for signs of damage. The rubber blocks in the motor mounts can crack, split, or show other damage that will require replacement. Examine hydraulic mounts for signs of fluid leakage, corrosion or other damage. The mounting plates that secure the mounts to the vehicles frame may also corrode or break.
3. Have the assistant start the vehicle. While you stand off to the side of the vehicle to observe the engine, have the assistant depress and hold the brake pedal and shift the car into drive. Watch the engine for rapid or excessive movement. The engine should move less than ½ an inch when placed into gear. A banging noise may also be a sign of a faulty motor mount.
4.
Shifting the car between drive and reverse will cause the engine to move.
Have the assistant place the vehicle in reverse and again watch for movement or noise. Have the assistant place the car back into park and turn off the vehicle.
5. Use pry bar to flex motor mounts. Any looseness in the mount will require replacement of the motor mount.
6. Use the pry par to check for play between the motor mount and the mounting surface of the engine or transmission. Play between the motor mount and mounting surface may be a result of bolts that come loose.

Do It Yourself Oil Change for a BMW 325i


1. Drive the vehicle onto the ramps and engage the emergency brake.
2. Slide the oil bucket beneath the vehicle at the oil plug location. BMW uses a skid plate with an easy access cover for the oil drain plug. Place the oil bucket beneath this access panel.
3. Open the access panel (in the center of the skid plate and labeled). Remove the oil plug using the 17 mm wrench. Allow the oil to drain until you have only a few drops dripping out. Replace the oil plug and tighten to between 20 and 25 foot-pounds of torque using a torque wrench. Leave the access panel open.
4. Remove oil filter housing cap using a filter strap wrench or by hand. You can use an adjustable wrench if desired. The cap is located center-front of the engine compartment, directly in front of the fan, accessed from above the engine. Pull the cap and filter out. The filter removes with the cap.
5. Replace the filter by sliding the old one off of the tube attached to the cap and sliding the new one onto the tube. Inspect the rubber grommets at the base of the tube and above the threads on the cap. Replace with the rubber grommets included with the new filter if you notice signs of looseness or damage. Reinstall the cap by hand and tighten one-quarter further with a strap or adjustable wrench.
6. Remove the oil fill cap. Pour 6.9 quarts of synthetic 5W-30 motor oil into the oil fill tube (labeled on top of the engine). Replace the oil fill cap and start the vehicle. Allow the motor to run for 2 minutes. Monitor the access panel beneath the vehicle and the oil filter cap for signs of leaks. Leaks would imply a damaged gasket or improper tightening. Correct the error and retest.
7. Close the access panel for the oil drain plug. Check the oil level with the engine oil dipstick. Fill as necessary.

How to Flush the Power Steering in a BMW


1. Turn off the engine and jack up the front of the vehicle using your car jack. Wrap plastic wrap around the power steering pump and the belt surfaces surrounding it. The power steering pump is located directly under the steering wheel and is cylindrical in shape. Open the reservoir, located on the left side of the pump, and use a syringe to remove the fluid inside. Puncture the reservoir with the syringe and slowly pull back the syringe to extract the fluid. Continue by opening the M16 banjo fitting on the pump itself and allow the remainder of the fluid to drip down into a pan below.
2. Turn the key in the ignition to release the steering wheel from a locked position. Slowly rotate the wheel to drain any remaining fluid that may be stuck up closer to the wheel itself. Remove the hollow bolt (the fastener composed of a threaded bolt and a spring) with your wrench and install the new crush waters onto the banjo fitting by tightening them into place. Crush waters are doughnut-shaped fastening devices that hold the banjo fitting in place. Torque the banjo fitting until it reaches approximately 40 nanometers (Nm).
3. Remove the plastic from the accessory belt and refill the reservoir with power steering fluid. Make sure to keep the fluid levels between the minimum and maximum guidelines. Rotate the wheel slowly from one side to the other. As the wheel turns, the fluid levels in the reservoir will drop as the fluid is being moved up closer to the wheel. Continue to fill the reservoir until the fluid level is once again between minimum and maximum. Place the reservoir cap back on and tighten until it is firmly in place.
4. Start the engine of the vehicle and slowly rotate the wheel from one side to the other. Repeat ten times and return the wheel to the center before turning the engine off. Reopen the reservoir and check the dipstick to ensure that the fluid levels are still above the minimum.
5. Lower the car from the jack by pressing the downward arrow button on the car jacks control system. If the dipstick shows that the fluid levels are still above the minimum, the car is safe to drive as soon as it has been removed from the jack.

How to Tow With a Mercedes ML320


1. Determine the towing capacity of your model and year of ML320. This information can be found in the owners manual. Calculate the total mass of the trailer by adding the weight of the trailer to the cargo. The trailers weight will be printed on the trailer data plate under gross trailer weight.
2. Determine if your Mercedes can tow the trailer by comparing the towing capacity to the total trailer mass. The trailers weight must be less than the towing capacity for a safe trip.
3. Connect the trailers coupler to the vehicles hitch by lowering it on. Lock the coupler in place by lowering the latch and securing it with a hitch pin.
4. Fasten the right trailer chain to the left side of the vehicle hitch and the left trailer chain to the right side. The crossed chains will catch the trailers tongue in the rare circumstance the two become disconnected.
5. Connect the trailers electrical connector to the vehicles electrical receiver by pushing the two together. If the connections do not match, an adapter can be purchased from a trailer store.
6. Drive slower than normal to compensate for the reduced braking and handling. Take corners slower and wider than normal while still maintaining your lane. Remember, when changing lanes, you will need additional space to compensate for the length of the trailer.

How to Install a Cone Filter in an Audi A4


1. Open your hood and locate the air filter box and intake tube. Turbo models will feature a heftier intake that attaches to the turbocharger, while naturally aspirated engines have intake that attaches to only the throttle body.
2. Disconnect the electrical wiring, hoses and mass air flow meter that attach to the factory intake tube and set aside for use with the new intake system. Unfasten the hardware that holds the intake tube in place and remove slowly, careful not to spill any debris. If necessary, use a flat-head screwdriver to assist you in removing the intake tube.
3. Unscrew the bolts that hold the stock air filter box into place. Remove this factory intake box completely and dispose of it properly, as you will not need the filter or its housing box for the new install.
4. Check the new intake tube and count the number of holes that are drilled into the side. If there are more holes than hoses that attached to the old setup, plug the unnecessary holes with the grommets that came with your intake kit.
5. Attach the new intake tube to your A4 directly as the old one was removed. This part will mimic the old intake tube in design and functionality, while the filter itself will be positioned differently and provide better performance. Secure the intake tube with the silicone coupling that came with your cold air intake kit. There should also be a clamp ring that came with your kit to hold the silicone coupling and intake tube into place.
6. Attach the downward piece of the intake tubing system to the newly installed tube from Step 5. By this point, the intake tube should extend to the front of the engine bay and underneath the front of the car. The cold air will come in through the bottom of the front side of the vehicle, increasing horespower and fuel efficiency in your Audi A4.
7. Spray down the new air filter with the necessary lubricant before installing. Position the cone air filter that was provided in the cold air intake kit onto the downward intake tube. Tighten the clamp fitted around the cone filter to secure into place. Reconnect any remaining hoses and wiring that were removed at this time.

How to Put a Third Row Seat Into An Audi Allroad


1. Drive the Audi Allroad somewhere where there is ample room in the rear to load the seats, and enough room for the trunk lid to open fully. Place the Audi in Park and pull the parking brake to keep it in place.
2. Turn the Allroad off and go to the rear. Open the trunk lid and extend it fully. Remove any items you have in the rear of the Audi. Fold the back seats down for additional maneuvering room, by pulling up the latches on either side of the rear seat, and then pushing the seat backs down.
3. Lift the third row bench seat up and slide it into the rear of the Audi with the seats facing the rear. If the third row bench is too heavy for you, then have an assistant help you. Align the bolt holes on the bottom runners with the four bolt holes in the floor. A flashlight can be very helpful.
4. Drop a bolt into each bolt hole and rotate them down by hand. Once all the bolts are in place, wrench the bolts down, until they are flush with the bolt holes. Push on the seat to make sure it does not budge under pressure.
5. Close the rear of the Audi, fold the rear seats back up, and turn the car on. Take the Audi for a test drive and listen for any creaks in the third row that would indicate looseness. Have the assistant ride in the third row to check this as well.

How to Change the Transmission Fluid on a ML430 Benz


1. Park the ML430 on a flat surface and make sure the engine is cool. If the car has been driven recently, wait at least 30 minutes for the heat to dissipate. Raise the car on jack stands to reach the underside of the engine more easily. Slide under the car and locate the transmission drain pan. It is a large, metal tank held with eight bolts beneath the middle of the engine.
2. Place a collection pan beneath the drain pan. Use the 1/2-inch socket wrench to remove all but one bolt on the drain pan. Wait 10 to 15 minutes for the fluid to drain into the collection pan. When it stops spilling from the side, place one hand on the drain pan and remove the final bolt. Lower the pan and pour the remaining fluid into the collection pan. Wash out the drain pan and bolts.
3. Remove the transmission filter under the drain pan with the 3/8-inch socket wrench. Attach the new transmission filter with the same bolts removed from the old one. Reattach the drain pan and lower the car from the jack stands.
4. Pop the engine hood by pulling the hood-release lever underneath the steering panel. Locate the yellow transmission dipstick above the drain pan. Pull it out and place a funnel into the tube. Pour in three quarts of five-speed transmission fluid. Replace the dipstick and close the engine hood.
5. Pour the used transmission fluid into a leak-proof container and take it to a recycling center. Many auto repair and auto parts shops also accept used car fluids.

How to Reset the Windshield Wipers on a 1990 Audi Quattro 80


1. Lift the hood of the car and locate the wiper motor, which is located on the driver side of the car, directly underneath the windshield wipers. Remove the wiper motor´s plastic cover by loosening its fastening clips -- this can be done by hand. Locate the bolt in the center of the wiper motor, remove it with a socket wrench and set it aside.
2. Run your windshield wipers through one complete cycle (the easiest way to do this is to activate the windshield washer, which runs your wipers through one cycle and then stops them in the parked position). This will not actually move the wipers, as the wiper bolt is removed, but you will notice the motor moving.
3. Push the wipers down until they are in an all-the-way-down position. This will hide the spot where the wiper bolt was attached -- the passenger wiper linkage will conceal it from view.
4. Pull the passenger wiper linkage away from the wiper motor. Use your hands, but do not use too much force, as that could break or bend the linkage. With the passenger wiper linkage removed, reattach the wiper bolt to the wiper motor, and make sure that the driver side wiper linkage is still in the all-the-way-down position before reattaching the wiper bolt.
5. Turn on your windshield wipers to confirm that they have been correctly reset. Only the driver-side wiper will move at this point, but because the wipers work in tandem, a correctly positioned driver wiper indicates a correctly positioned passenger wiper.
6. Reattach the passenger wiper linkage to the wiper motor. Use a mallet to tap it back into place, reattach the wiper motor´s plastic cover by tightening its fastening clips and then close the hood. Run your wipers again to ensure that both are correctly reset.

How to Reset the Check Light in a BMW


1. Create a grounding apparatus for the diagnostic connector. Attach the copper clip to the large end of the insulator. Connect the copper wire to the skinny part of the insulator. Connect the other end of the wire to a banana plug. Connect the wire on the BMW pin to the other side of the banana plug.
2. Turn the key in the ignition half way so that the lights come on but the engine is not running.
3. Open the hood and locate the ground plug in the electrical system near the engine. It is usually a small octagon shaped screw or nut close to the data link connector. Attach the open side of the copper clip to the ground plug.
4. Locate the data link connector and unscrew the cap exposing the pins underneath. Press the end of the male pin into the number 7 plug inside the data link connector. This is usually the middle right hole on a 15-point connector and the very bottom hole on a 20-point connector. Hold the pin in place for three seconds to reset the oil light, and nine seconds to reset the inspection light.
5. Remove the pin once the light resets. Screw the cap back on. Turn the engine off, then turn it back on. If the lights are still there, try resetting the lights again. Once the lights remain off, turn off the engine and close the hood.
