View Full Version : 2006 530xi,oil sensor fail?
changed my oil and after month says low on oil,went to dealership and he added quart of it and he saw white smoke(barely visible) at high rpm...yesterday after 200 km again low oil massage it was red on level...today its on orange but i didnt filled it..and i dont see white smoke ever only at dealership that time,what do you think?
white smoke indicates coolant is internally leaking. Blue smoke indicates oil is internally leaking.
With that much variation on oil level within a relatively short duration, I'd say oil level sensor may be the culprit. On the bright side, the oil level sensor is readily accessible on the bottom. On one my previous MB car, lower pan had to be removed to replace the oil level sensor. Good luck.
