It is also compatible with various other BMW models, including the 2 Series F22, 3 Series F30/F31, and 4 Series F32/F33, as well as certain diesel variants like the 328d .
Manufactured to original equipment specifications, this sensor is available from OE-quality suppliers such as Febi Bilstein and Vemo . It features a 3-pin connector and is built to withstand the extreme thermal and chemical environment of the engine oil pan . The part number 12618608781 supersedes earlier references including 12617636296 and 12618507676 . A failing sensor often triggers an oil level warning light or inaccurate readings . Replacing a defective unit with this premium sensor restores accurate oil monitoring and reliable engine protection.
