BMW Electrical Sensors, Switches, & Relays for BMW 4 Series F33 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

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.

Camshaft position sensors are electrical sensors that monitor the rotational speed and position of a camshaft. This signal is used by the DME to control fuel delivery and spark timing. If your camshaft position sensor is faulty, it can result in check engine lights, rough idle or running conditions, limp mode, or no starts. Replace your cam position sensor with this high-quality replacement to restore smooth engine operation.

The camshaft position sensor communicates the position of the camshaft to the computer. This helps the computer to calculate proper spark and fuel control. If you're struggling with CELs, hard starts or no starts, stalling, and/or a rough idle, you may need to replace the cam position sensor.

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.
