BMW Electrical Sensors, Switches, & Relays for BMW 3 Series G20 (2019+)

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 relay is used for the SMG system on the E46 M3 and various applications including secondary air systems on other BMW's. If you find that your SMG-equipped E46 M3 is not starting, this is one of the first places to check as it controls power to the hydraulic unit (the car will not start without hydraulics). Buy one to fix the issue and buy a second so you're not stranded in the future!

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.

BMW has eliminated the dipstick in favor of electric oil level sensors located in the bottom of the oil pan. These sensors are designed to monitor both the oil level and oil condition, alerting you when the oil level is too low or the quality of the oil has dropped and should be changed. Unfortunately, like many BMW electrical components, these sensors are prone to failure and can result in improper level and quality readings. If you recently changed your oil and know the readings are incorrect, there is a good chance your sensor has failed. We recommend replacing your oil level sensor, in this case, to ensure you are always seeing proper levels and oil condition. Luckily, this sensor is easy to replace and could save you from potentially catastrophic issues later on.
