How to Replace an MMI Switch

1. Lay a thin rag over the MMI switch you wish to remove. Ensure that it's fully covered, but that the rag isn't too thick. You will know that you need to use a thinner rag if the pump wrench is not able to obtain a firm grip.
2. Adjust the pump wrench to its wider setting and position it around the switch.
3. Tighten the pump wrench slowly until it's firmly, but gently, grasping the rag-covered MMI switch.
4. Pull up on the MMI switch's knob in a firm motion. Be sure to pull directly up with firm, but not violent, force. Wiggle it slightly to loosen it if you encounter some trouble.
5. Place the new MMI knob over the switch's input and push down gently and firmly until you hear it audibly snap into place.

How to Tow a Boat With an Allroad

1. Add the weight of the trailer to the weight of the cargo. The trailer's mass is printed on its data plate under gross trailer weight. The result must be less than the towing capacity of your Allroad.
2. Reverse the Allroad up to the trailer, aligning the hitch under the coupler. Have a friend help guide you to the trailer.
3. Lower the trailer's coupler onto the hitch and lock it in place with a hitch pin. Connect the trailer's chains to the hitch, crossing them under the coupler.
4. Push the trailer's four-way electrical connector into the vehicle's receiver. Test the trailer's lights respond properly to the vehicle.
5. Walk around the trailer and vehicle double-checking all the connections.
6. Drive slower than normal to compensate for the reduced handling. Leave twice the normal braking room to assure you don't rear-end the vehicle in front of you. Standard braking room involves one car distance for every 10 miles of speed. Double that when towing a trailer with a boat.

How to Replace the Oil Filter on a BMW

1. Locate the oil filter on the BMW's engine. It will either be on top of the engine near the front or under the engine.
2. Loosen the oil filter cover using the socket wrench and correct socket (size will depend on the make and model of your BMW and its engine size).
3. Remove the oil filter cover. Note that the oil filter itself will likely come out as well.
4. Throw away the old oil filter and rubber o-ring that were inside the oil filter cover.
5. Wipe off the inside of the oil filter cover with the rag or towel to remove any contaminants.
6. Lubricate the new o-ring that came with the BMW oil filter insert kit.
7. Install the new oil filter and lubricated o-ring in the opposite order they were removed. Install the new lubricated o-ring by pressing it into place, then install the new filter. Depending on the engine, the filter may be installed in two orientations or it may only have one correct orientation (if the latter is the case, it will not be possible to install it in the wrong orientation).
8. Install and tighten the oil filter cover using the socket wrench. If a torque wrench is available, torque the oil filter cover to 18 ft-lbs. If a torque wrench is not available, tighten until it is difficult to tighten further, but do not overtighten.

How to Repair a BMW Hood Emblem

1. Clean thoroughly around the emblem so that the paint does not get scratched when it is removed. Use a soft bristle brush to loosen and remove any loose dirt trapped around the edge of the emblem.
2. Wrap masking tap around the end of a flat head screwdriver so that the paint is protected when you use the screwdriver to pry off the emblem. Carefully slide the screwdriver between the emblem and hood and pry the emblem up. Work around the edge, prying up a little at a time until the emblem pops off the hood. You can also use a credit card or similar object to remove the emblem.
3. Open the hood. Locate the rubber grommets that the studs on the back of the emblem were fastened to. The studs on the emblem go through small holes in the hood and are then held in place with these rubber grommets. The new emblem will come with new grommets. Remove the old grommets and discard them.
4. Clean the area on the outside of the hood where the emblem was installed. Install the new rubber grommets onto the studs on the back of the new emblem by sliding them on. Line the studs and the rubber grommets up with the holes in the hood and gently press the emblem into place.

How to Wire Headlights in an Audi RS2

1. Gather the wires on the back of the new headlight into one pair of positive wires and one pair of neutral wires. Different headlights may have different colored insulation to indicate the positive and neutral wires. In general, for aftermarket headlight assemblies, the positive wires are red, and the neutral wires are black.
2. Strip 1 inch of insulation off of the end of each wire.
3. Braid the 1-inch leads of the positive wires together. Braid the 1-inch leads of the neutral wires together.
4. Insert the braided leads of the positive wires through one female crimp connector. Clamp the connector over the leads with a pair of pliers. Wrap the connection in electrical tape to prevent moisture from entering the circuit. Repeat this process for the pair of neutral wires.
5. Strip 1 inch of insulation off of the end of the spare positive wire and 1 inch of insulation off of the spare neutral wire that comes with the new headlight assemblies.
6. Insert the bare lead of the spare positive wire through a male crimp connector. Clamp the connection down with the pliers. Apply electrical tape to the connection. Repeat this process for the spare neutral wire.
7. Connect the negative lead of a voltmeter to the negative terminal of the vehicle's battery. Connect the positive lead of the voltmeter to the positive wire on the vehicle's headlight wiring harness. The positive wire is the one with power coming through it. In general, this wire is covered in red insulation.
8. Connect the spare positive wire to the positive wire from the headlight wiring harness with a quick connector. Clamp the connection down with the pliers. Repeat this step for the spare neutral wire and the neutral wire from the headlight wiring harness.
9. Insert the male crimp connector from the spare positive wire through the female crimp connector from the pair of positive wires coming from the headlight assembly. Wrap the connection in electrical tape. Repeat this process for the male crimp connector on the spare neutral wire and the female crimp connector on the pair of neutral wires.
10. Repeat these steps for the other headlight assembly.
