Disa Valve Repair Kit

The M54 DISA valve is a great thing, but it has some faults from the factory.  In fact, if neglected, older DISA valves begin to rattle and the pin can break off and actually get sucked into the engine causing damage.  Our friends at German Auto Solutions came up with a rebuild kit that will make sure it lasts forever.  

The DISA valve, otherwise known as the "Intake Manifold Adjuster Unit", is located on the side of the intake manifold and is a common failure on the M54 BMW engines. The failure is caused by the type of materials used in the manufacture of two of the three key valve components.

During normal engine operation the bell crank lever and flapper valve vibrate against each other where the hex shaped portions contact each other. These vibrations start a wear process which will cause the tiny glass fibers in the flapper valve to erode away the male hex portion of the weaker bell crank lever. As soon as the erosion starts it's all down hill from there until the hex is completely worn away. The symptoms of a worn DISA valve include rough idle, lean engine codes and lack of low to mid rpm power.
