How many miles before you should change the timing belt on a BMW?

BMW recommends changing the timing belt on many of their vehicles every 100,000 miles or 10 years, whichever comes first. However, some models recommend changing the belt more frequently, such as the 3 Series and 5 Series, which have a recommended replacement interval of 60,000 miles or 6 years. It's important to check your vehicle's maintenance schedule for the specific timing belt replacement interval for your model.
