why Automobile oil table does not match with the actual level?

On the decline of oil gauge pointer speed rate is not the same of this phenomenon, there may be a design issue, it is not in accordance with the linear design of some models of the oil itself, slow, fast before the half after the half of this phenomenon should be relatively normal. Oil table pointer is not stable, may be the level sensor oil gauge problem. If confirmed to fill full of the oil, oil pointer is not to the top, should be the meter display problems. These problems to a repair shop on it. source: http://www.greebid.com/

POSS WARRANTY AT DEALER

The oil level must be checked at normal operating temperature. I've never seen BMW produce a "bad" dipstick. Oil expands substantially as it reaches normal op temp. You should take this very sophisticated, technologically advanced piece of engineering beauty to a trained BMW Specialist (a specialist is someone who only works on one make of vehicle). There are many qualified independent, as well as dealer choices out there. Remember, there is no such thing as a Euro Specialist, or a Japanese Specialist, or a Domestic Specialist, or even a German Auto Specialist - the term would be an oxymoron. A German Auto Specialist would have to be proficient in seven different makes - this is not possible anymore "Jack of all trades, master of none".
