Each time we perform a maintenance service on your BMW, our main priority is to ensure the safety and reliability of your vehicle. We change the oil, check fluid levels, etcetera, but the real value of our service is our expertise and familiarity with the problem areas, common failure points, and the practical service needs of your particular BMW model.

Service Maintenance Schedules

BMW has traditionally provided very comprehensive maintenance recommendations and schedules that have been aimed not only at ensuring maximum safety and reliability, but also to provide the longest possible service life for your BMW and its components. At European Motorsport, we assume that your intentions are to keep your BMW indefinitely, and that you want it to provide safe, reliable, comfortable and fun transportation for you throughout this time. This is why we strongly recommend not only following the factory maintenance schedules, but also including the intermediate oil services as shown below (although these are not required by BMW for the “new car warranty”).

Since 1983, BMW has used a service interval computer to determine (“indicate”) when one of the three main services are due. If you own a later model, normal driving in our area will have 9,000 to 15,000 mile “indicated” service intervals. “Indicated” services are shown below in bold.

Service maintenance schedules for models 1999 and later generally appears as follows:

  • 7,500 miles – intermediate oil service (O/S1)
  • 15,000 miles – Oil and Safety Service (O/S2)
  • 22,500 miles – intermediate oil service (O/S1)
  • 30,000 miles – BMW Inspection I (I/1)

Our experience over the years has shown us that owners who maintain their BMW’s well, tend to keep their cars longer, are happier with their ownership/driving experiences, and are let down by their cars very rarely. Ninety percent of our customers maintain their cars according to the recommended schedules and realize the cost effectiveness of proper vehicle maintenance over the years. The others apparently think that all one needs to do to maintain a BMW, is to take it in to a “quick lube” now and then (and unfortunately get what they pay for) and bring it in to us when they have a problem. As expected, these are the cars that we are more likely to see being towed-in to our shop. Many times these (often very expensive) problems could have been prevented if the car had received proper maintenance (An anonymous reviewer: “If you think a good BMW mechanic is expensive, just see what happens when you try a cheap one”).
