Drastically improve the looks of your vehicle while improving your vehicle's handling characteristics and/or easily adjust your wheel fitment to allow for the proper clearance when installing parts such as new wheels, big brake kits, or lowering suspension components.Interference from components such as shocks, springs, or control arms are a common issue when installing wheel that are not a direct OE size replacement.

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.

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes.

If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage.

Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold.
