Electrical relays can lead to a lot of confusion when you attempt to resolve an issue. Often times relays overheat and cease functioning, making it appear the part it controls has failed. Luckily we stock a multitude of Genuine BMW and OEM relays to help you get your BMW or MINI back on the road and running like new!
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!
