This sensor monitors the position of the Valvetronic eccentric shaft and feeds data back to the ECU. The common issue with this sensor is that it gets contaminated with oil and fails. It doesn't give a fault code or check engine light, however. What you would notice is sluggish driving, hesitation, poor performance, jerky shifts from an automatic, and other drivability issues. These types of issues are typically diagnosed as ignition coils (which are their own issue altogether) but this sensor may also be faulty.

The eccentric shaft sensor is located at the front of the cylinder head and is only accessible with the valve cover off. It's easy to check for oil by removing the engine trim cover (the outer cover with the BMW roundel), unplug the sensor, and look inside. If oil is present inside, or even on the valve cover itself, the sensor is likely contaminated or ready to fail. You can wipe or clean the oil from sitting inside the sensor but it will come back.

If you're planning this job make sure you have our Valve Cover Overhaul Kit, which includes a new seal for the eccentric sensor as well as the rest of the valve cover and Valvetronic gaskets. You can add the valve cover set from the options below.

Sway bar end links connect the swaybar to the rest of the suspension, preventing body roll and keeping everything in line in tight turns. This exposes these links to a high amount of stress and pressure, often leading to split bushings and sloppy body control and knocking noises. OEM Lemförder sway bar links are the perfect option to restore body control and eliminate knocking noises.
