Tar Heel Faithful
The N52 and N54 motors do not have the dipstick, regardless of model. The N57 diesel motor does not.
Sorry, my typo. I meant that it does; it was one of the things I noticed when I test drove it.If you are saying the M57N2 motor that is in the 335d doesn't have a dipstick, you might want to actually check out a 335d. Hint: look toward the rear of the motor on the drivers side for a red plastic grip loop....
