My wife's car is a 2013 BMW 335i with M-Sport package. The engine has no dipstick so the only way to check the oil level is using the menu-driven display. However, this never completes. Specifically, when I start, the screen looks like this: Then it seems to attempt to do what it's supposed to do for a while: But it never seems to complete. In particular, the percent complete goes to somewhere between 17% and 30% I think, and then reverts to the first screen. There is a separate menu item which is to display the oil level and it shows this:
The car is new to me, and the manual is somewhat vague on what is supposed to happen. So my questions are:
- Shouldn't this go to 100% and show an actual oil level?
- If that's correct, is this possible to fix at home, or is this dealer-only territory?
- Any clues as to how to go about troubleshooting this?
