On the track or on the street, your BMW’s electrical architecture demands absolute consistency. A degraded positive battery cable introduces unwanted resistance, leading to weak starts, alternator strain, and erratic module behavior. When it’s time to replace a compromised factory cable, you don’t need over-hyped marketing—you need a part that fits precisely and restores factory grid integrity.

This is a replacement Manifold Absolute Pressure sensor Located on the charge air cooler. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP sensor likely needs to be replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.

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.
