This low-pressure fuel sensor is commonly a cause of an "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine. This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware.
