How to Check the Oil Level on a 2007 BMW 328

by Chester Rockwell

The 2007 BMW 328i is a part of the latest generation of 3-Series which BMW has named the E90 platform. It was with the introduction of the E90 that BMW also added electronic monitoring of the engine oil level and quality to the 3-Series' on-board computer.

Check OIl Level Using Dipstick

Park your 328i on a level surface. Turn off the engine, and open the car's hood.

Locate the dipstick's handle in your engine bay. It will be on the driver's side of your engine bay, opposite of the filler neck used to add new oil.

Gently pull the dip stick out, and wipe it clean with a paper towel.

Slowly re-insert the dipstick into the tube all the way, and pull it out again.

Check the engine oil level visually by looking at the markings on the bottom of the dip stick. The oil level should be between the notches at the bottom and top of the dipstick's measuring end. The bottom-most marker designates the minimum oil level while the top marker indicates maximum level.

Check Engine Oil Level Using On-Board Computer

Insert your ignition key into the 328i, and turn the vehicle on.

Press the small vertical button on the front of your turn signal stalk until the display between the speedometer and tachometer reads "OIL" and an oil icon is displayed.

Press the button located at the end of your turn signal stalk to reveal a digital reading of the engine's oil level. If more oil is needed, the display will show "+1 qts". If the oil level is fine, the display will read "OK."


  • The 2007 328i has a dipstick; however some E90 models produced after 2007 have no dipstick at all and the oil level can only checked by electronic means.
