For U Solution

You lose your car keys on occasion. Almost everyone has done it, or will do it at some point in his life. Most of the time, your keys are found before too long and you get to carry on with your plans. If you find yourself in a situation where you simply cannot find the keys to your BMW, youll have to call your local dealership and have a new key made. You can get a new key for your BMW without the title, but you will need some other form of proof that the car belongs to you.

Instructions

1

Determine the year of your BMW. If its an older model, made before the new millennium, you can call any locksmith to request a key for your car since the car has no computer system. If your car is a later model, youll need to contact your local BMW dealership.

2

Inform the locksmith or BMW dealership that youve lost the keys to your car and need to replace them. Provide them with some sort of documentation proving your ownership. Ideally, your vehicle title is the best proof of ownership, but if you cannot find your title, you can use your registration or insurance card.

3

Wait while a new key is made for your car, and pay the locksmith or dealership for their service and for your new key.

You can reset the computer on your 1990 BMW 750II right from your home garage, saving yourself time and money. The vehicles computer warns you of any and all malfunctions the vehicle is having. It alerts you by illuminating warning lights and service lights on the BMWs instrument panel. After you have had the vehicle serviced or repaired by a qualified mechanic, you or your mechanic will need to reset the vehicles computer in order to keep it functioning properly.

Instructions

1

Locate and open the fuse panel cover. This can be found in the drivers side dashboard. Pull down on it from the top with your fingers.

2

Find the large port within the fuse panel. It will be the same size and shape as the connective end of the BMW OBD reset tool. This small computerized hand-held device can be purchased from your BMW dealer.

3

Plug the tool into the port.

4

Put the key into the ignition and turn it to the "On" position. Dont start the engine.

5

Wait for the tool to automatically clear all the trouble codes. Unplug the tool and close the fuse panel cover. Start the engine and verify that all service and warning lights of the instrument panel have shut off. The computer has been reset.

Bayerische Motoren Werke, the company that makes BMW cars, also manufactures motorcycles. The BMW 1100 LT cycle is similar to a car, in that both vehicles use a battery to power their engines. However, in the case of a motorcycle, motorcycle pros like those at the website Cycle Maintenance recommend extreme diligence when jump-starting the bike if the battery goes dead, because if you do it improperly you can fry the bike and its electrical system.

Instructions

1

Put your cycle close to the front portion of your automobile. Do not allow either your cycle or car to touch. Take out each set of keys and power off both your car and motorcycle.

2

Open your automobile hood and take out your motorcycle seat so your batteries lie in plain sight.

3

Attach your red jumper cable to the terminal with a positive connection on your car battery. Attach your other red cable to the positive portion of your cycle battery.

4

Attach the opposite jumper to the negative terminal of your car. Attach the opposite end of the cable to a metal portion of your cycle, like the rear axle.

5

Start your BMW 1100 LT. However, keep your car turned off, because you may harm the electrical portion of the vehicle if you turn it on. Take off all of the cables in the opposite order from the way you installed them.

A cars differential receives the torque force generated by the engine and transmission, via the driveshaft, and distributes it to the driven wheels. The differential uses gears to reduce the speed of the input force -- the engine spins at higher RPMs than the wheels. The difference between the input speed and the output speed is called the final gear ratio. Every BMW differential has the final gear ratio stamped on it, as well as a letter designating whether it is an open or limited-slip differential. Depending on the year and model of your BMW, the stamp may be on either side or the rear of the differential, typically found on a flat area adjacent to a bolt. Since BMWs are performance-oriented cars, it may be necessary to raise the rear of the vehicle in order to view the stamping.

Instructions

1

Raise the vehicle using a floor jack, and place it securely on jack stands if necessary.

2

Locate the differential between the two rear tires. Depending on the year and model, the stamp may be on the either side or on the rear of the differential. Look for a flat, smooth area next to a bolt, with a series of letters and numbers stamped on it.

3

Clean the stamping using a rag and wire brush, if necessary. Depending on the age and use of the vehicle, a significant amount of grime may have accumulated.

4

Decode the stamping. It will be comprised of eight characters. The first is a letter, most likely an N or R, which designates an open differential. The letter S signifies a limited-slip differential. After that will be three digits, such as 345. This indicates a final drive ratio of 3.45:1. After that will be four digits, such as 0722, which refer to the part number of the differential.

Late timing in a BMW is no different than late timing in the combustion engine of any car. Late timing refers to the state of combustion in the engine and exhaust system.

What is Late Timing

Late timing refers to the timing of the spark to ignite the fuel within the cylinders. When the spark fires late, the exhaust temperatures tend to go too high as the exhaust valves open before combustion is complete. As the combustion was not complete, some additional combustion may occur in the exhaust system.

Potential Problems

The most obvious drawback is a lowering of engine efficiency and overall fuel efficiency, as the engine does not get the full benefit of the combustion cycle. The car is also apt to run more sluggishly. Also, since full combustion is not occurring, carbon may build up on the valves and possibly build up in the catalytic converter.

Potential Solutions

The make and model provide so many variables to consider as equipment has changed dramatically over the years. Adjustments to the distributor can be considered. Additionally, camshaft or crankshaft sensors may require adjustment. Newer cars have engine computers that typically self-correct per the information that the sensors feed them. If this is not occurring, most likely a faulty sensor is the cause.

The BMW 330i is a compact executive car that was in production from 2000 to 2007. It had nn anti-lock braking system, or ABS, as a standard feature. The ABS had an electronic brake control module, or EBCM, that controlled the hydraulic pressure to each brake caliper. This gave the car improved braking. The procedure for replacing the EBCM is generally the same for all versions of the BMW 330i.

Instructions

1

Remove the cable from the negative terminal of the battery with a socket wrench. This prevents anyone from starting the engine during the EBCM replacement procedure.

2

Remove the cover for the hydraulic control unit, or HCU, on the right side of the engine compartment. The HCU is a cube-shaped component with hydraulic brake lines connected to it. The EBCM is a smaller, narrow component on top of the HCU.

3

Release the clamp on the EBCM. Pull off the right side of the multiple plug from the EBCM, and disconnect the left side of the plug from the EBCM. Disconnect the mounting bolts from the EBCM with a socket wrench, and remove the EBCM from the vehicle.

4

Install the new EBCM to the HCU, and fasten the mounting bolts for the EBCM with a socket wrench. Connect both halves of the multiple plug to the EBCM.

5

Attach the clamp on the EBCM, and replace the cover for the HCU. Attach the cable for the negative battery terminal with a socket wrench.
