BMW Electrical Sensors, Switches, & Relays for BMW 3 Series E46 (1999-2005)

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.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:
1985-1991 E30 318i, 318is, 325e, 325i, M3
