Many newer BMW's no longer have oil dipsticks and rely on oil level sensors instead. It's been mentioned that one possible indicator of impending failure is beige/light brown sludge on the bottom of the oil filler cap on these engines.

Now that I think about it, I don't remember any failures on any of these new engines but maybe I've forgotten.

Could eliminating the dipstick actually be an attempt by BMW to mitigate the problem?
