BMW Electrical Sensors, Switches, & Relays for BMW A90 MKV Supra B58 3.0L

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!
