The on board computer of the BMW's have the capability to do couple tests using the instrument cluster. In order to do that, you need to unlock the instrument cluster first. Few of these test are Mass Air Flow sensor test, engines temperature, fuel gauge or #9 test charging test. There are a couple threads on the E39 section about how to unlock the instrument cluster and do the tests, or you might find them on youtube (few).
