BMW Electrical Sensors, Switches, & Relays for BMW 3 Series F31 (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.

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.
