BMW Electrical Sensors, Switches, & Relays for BMW 3 Series F34 (2014+)

Clear BMW chassis

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

This is a replacement Manifold Absolute Pressure sensor Located on the charge air cooler. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP sensor likely needs to be replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.

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.
