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.

Your vehicle’s ground strap plays a vital role in maintaining a healthy electrical system. Exposure to heat, corrosion, and constant vibration can degrade the strap over time, resulting in weak or inconsistent electrical connections. When the ground strap begins to fail, symptoms can include hard starting, flickering or dim lights, warning messages, erratic sensor behavior, or complete no-start situations. Replacing a worn ground strap restores proper current flow, protects sensitive electronics, and keeps your engine and electrical systems operating reliably.
