Your vehicle is equipped with numerous gauges to allow you to have a better idea of what is going on under the hood. By monitoring these gauges, you can prevent premature engine damage due to low oil pressure or high coolant temperatures. If one isn't functional though, you are in the dark as far as that system goes. One of the most vital is the oil pressure. Replace the sensor to get your gauge working properly again.

When BMW threw out the mechanical dipstick, they shifted the responsibility of protecting your engine entirely to the electronic oil level sensor. On the street or the track, knowing your oil level is non-negotiable. If your dashboard sensor readout is throwing errors or lagging, your N52, N54, N55, S55, or N63 engine is operating in the dark. This Febi Bilstein engine oil level sensor is an excellent, cost-effective alternative to expensive dealership parts counter pieces. Febi is an industry-trusted German manufacturer, ensuring this sensor reads with the exact same precision and calibration as original equipment. Keep your ultimate driving machine properly monitored and safe from oil starvation. Key Features Premium German Engineering: Manufactured by Febi Bilstein to match original BMW operational tolerances. Critical Engine Protection: Restores accurate iDrive/instrument cluster oil volume and temperature readouts. Exact Factory Fit: Features the correct 3-pin oval plug orientation for a seamless plug-and-play install. Track-Day Insurance: Ensures your electronic monitoring system functions flawlessly under heavy load. Turner Tip: Oil level sensors are notorious for failing due to age and repeated heat cycles. Because this sensor installs directly into the bottom of the oil pan, make this swap part of your next oil service kit checklist.
