Find Parts That Fit Your Vehicle

BMW Electrical Sensors, Switches, & Relays

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.

On the track or on the street, your BMW’s electrical architecture demands absolute consistency. A degraded positive battery cable introduces unwanted resistance, leading to weak starts, alternator strain, and erratic module behavior. When it’s time to replace a compromised factory cable, you don’t need over-hyped marketing—you need a part that fits precisely and restores factory grid integrity.

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.
