BMW Electrical Sensors, Switches, & Relays for BMW 3 Series E36 (1992-1998)

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.

This voltage regulator is a crucial component that controls the alternator's output, preventing overcharging by adjusting the current to maintain a safe range of vehicle voltage, thereby protecting the battery and electrical system. Symptoms of failure include dim lights, battery warnings, or a dead battery, often requiring replacement, which can be internal or external to the alternator.
