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!

This kit includes a new Genuine BMW Oil Level Sensor and three hex nuts to mount the new sensor to the oil pan. If the mounting stud bolts are also damaged, you will need 3 of BMW part number 07129904544. 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.

Replace your cam position sensor with this high-quality replacement to restore smooth engine operation.

Your vehicle’s ground strap plays a vital role in maintaining a healthy electrical system. Exposure to heat, corrosion, and constant vibration can degrade the strap over time, resulting in weak or inconsistent electrical connections. When the ground strap begins to fail, symptoms can include hard starting, flickering or dim lights, warning messages, erratic sensor behavior, or complete no-start situations. Replacing a worn ground strap restores proper current flow, protects sensitive electronics, and keeps your engine and electrical systems operating reliably.
