Your vehicle is an asset, in which you invest time and money. Getting the recommended maintenance done and keeping the service records increases the value of your car. Some auto owners believe that maintenance and servicing by car dealers is a scam and too expensive; they would like a way to get it done cheaply and with efficiency. Either a self repair or with the help of the auto manufacturer. The Wall Street Journal has an article on the risks of basic auto maintenance and repair self repair stories:
The average vehicle on the road in the U.S. is now nearly 11 years old, according to auto-market data firm R.L. Polk Co., which also says buyers of new cars are keeping them on average for nearly six years—well past the warranties for most components. When getting a mechanic to investigate a check engine light or replace an air filter can cost $50 or more, the motivation to master at least some basic maintenance is clear.
Companies that compile detailed how-to manuals—such as the U.K.'s Haynes Publishing—now post their products online. Ebay and other services make finding parts a matter of point and click, instead of trolling through junkyards. Mr. Hughes, whose main business is restoring classic and custom vehicles, is passionate on the issue of high repair costs. "They don't want you to work on your car," he says. "They make their money on repairs."
It's a good idea to learn enough about the basics of auto maintenance to undertake simple chores such as changing air filters or replacing light bulbs, though even this can be tricky in some cars. Changing the oil is another step up in difficulty. You can damage your engine if you're not careful to use the right oil filter and replace the oil-drain plug without stripping its threads, or forget a leak-stopping gasket.
Automaker BMW has the onboard vehicle diagnostic system known as TeleService, which automatically diagnoses potential vehicle repair needs or maintenance requirements. It then transmits the request for service electronically to the automaker. BMW then forwards the request to any of its dealership closest to the owner of the vehicle. Obviously BMW does not think that self repair is recommended!
