How to Read BMW Service Status Lights

Reading Service Error Codes and Lights
1. Remove the fuse panel cover by pulling it down; or if your BMW uses a knob to "lock" the fuse panel, turn the knob counterclockwise and pull down on the fuse panel cover. The type of fuse panel cover you have will depend on the year of your BMW.
2. Locate the large, circular input on the fuse panel. This input jack is made for a diagnostic tool on all BMW vehicles. There is only one circular input on the fuse panel so it shouldn't be too hard to find.
3. Plug the diagnostic tool into the service input on the fuse panel.
4. Turn the ignition key to the "II" position and wait for a code to be generated by the tool. You will need a technical service manual in order to translate the code, but the diagnostic tool is the only way to read it.
Reading Regular Service Lights
5. Check the seven bars of light on your dash. If you have five green lights illuminated, this indicates a "normal" status, and no service is required. As the lights go out, this acts as a "countdown" to the next regularly scheduled service.
6. Check for all of the green lights to be out and one yellow light illuminated with the words "Oil Service" appearing underneath the bar of lights. This indicates that an oil change is necessary.
7. Check for one yellow light illuminated, all green lights out and the word "Inspection" appearing below the lights. This indicates that you need to have your BMW inspected. The service error code will determine what needs to be inspected.
8. Check for a red light next to a yellow light with either the words "Oil Service" or "Inspection" underneath the lights. This indicates that you must have service done on your BMW immediately and that it is not safe to drive your BMW until you have the required service performed.

How to Diagnose Faulty Fuel Pumps

1. Take your car onto a highway and travel at the posted speed. If the engine in your car occasionally misfires, you will notice a slight hesitation. A faulty fuel pump, particularly in the first stage of failing, frequently will falter a time or two then your engine runs smoothly for miles. Even a professional mechanic can misdiagnose the problem and recommend a tune up or a fuel filter instead.
2. Get behind the wheel of your car and press the gas pedal. If your car momentarily fails to accelerate, you probably have a fuel pump that's about to stop working. Often seasoned mechanics mistake a failing fuel pump for an oxygen sensor which is less expensive to replace than the fuel pump.
3. Start the car. If it doesn't start right away, don't rule out a faulty fuel pump. It won't start because the engine is robbed of the fuel it needs to do the job. Besides a faulty fuel pump, it could be caused by a myriad of reasons, including the timing belt or the fuel filter. Before you spend a substantial amount of money getting a new fuel filter installed, you would be wise to get a second opinion.
4. Climb a hill in your car and if you tend to lose speed, it is probably caused by a fuel system failure, with the fuel pump being a prime suspect. Often a fuel filter is all that needs replacing, but the fuel pump is a possible candidate for replacement.

How to Write an Ad to Sell a Vehicle

1. List the basic features of your car, and, if necessary, search online sources to obtain your vehicle's specifications. AutoTrader reminds you to list information, such as the vehicle's year, make, model and whether or not you are the original owner, and then add more details.
2. Review the car owner's manual or obtain additional information from Internet sites to verify details about the car. Websites have information about specific interior and exterior features and mechanical details about your model.
3. Prepare the first draft of your ad. Write down the correct make, year, model, sub model and color. Be sure you have the correct sub model, especially if it's not mounted on the car's body. For example, Mercedes-Benz, 1992, 300E, 2.6, Gold. The sub model for this car is 2.6.
4. Access the website for your car's make and model to find the exact name of the color. If the name of your car's color is unrecognizable, make a parenthetical note with a common name of a color. For instance, the Mercedes color Metallic Capri Blue can be described as 'Navy blue' in parentheses. Note the interior color as well.
5. Revise your draft to add more basic information and details about your car. Include the current mileage, condition and how long you have owned it. Use words and phrases such as 'excellent,' 'pristine,' 'needs body work' or 'transmission needed' to describe the condition of your car. Be specific and honest in your ad.
6. State why you're selling the vehicle. If it's true, assure buyers that you're not selling the car because there's something wrong with it. If there is something wrong, indicate this where you describe the car's condition.
7. Add something that appeals to the personal side of a business transaction. If spring is around the corner and you're selling a convertible, mention that it's fun for sunny days. If it's an SUV in the winter, describe how well the four-wheel drive handles icy roads.
8. State your asking price for the car. If you are willing to negotiate, use the acronym 'OBO' after your price, as in '$4,000 OBO,' which indicates 'or best offer.' If you are not willing to negotiate the price of your car, state that the price is 'firm.'
