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.

If you disassemble a worn out DISA valve and look at the bell crank lever it's common to not even recognize that it once had a hex shape on the protrusion. Once the hex is shape is worn off the lever, the flapper valve no longer opens and closes in a controlled manner by the rotation of the bell crank lever. The brittle flapper valve becomes free to slap around uncontrolled within the DISA support framework. This uncontrolled movement can lead to complete destruction of the flapper valve. The broken pieces of valve have no where else to go except through the intake manifold runners and through the motor, sometimes resulting in severe engine damage. Even a small piece of plastic broken off the flapper valve can hold an intake valve open, resulting in bent valves or much worse.

Since the only parts on the DISA valve that typically fail are the flapper valve, bell crank lever and housing seal, why replace the entire unit. Replace the failed internal parts with our lifetime warrantied upgraded parts and have a much more reliable DISA for 1/3 the cost.

At German Auto Solutions we thoroughly analyzed the DISA valve and engineered a solution that addresses all the weak points of the original design.

German Auto Solutions invented the DISA repair kit and is still the only kit made in the U.S.A.  Over 10,000 kits sold without a single known failure. Don't settle for cheap imported imitations.

    GAS BMW M54 2.5L DISA Repair and Upgrade Kit
    Your DISA rebuilding kit was part of an overhaul of the CCV system in my 325i.

    I worked with a friend who is a Senior Engineer for Pratt & Whitney aircraft engine company. Between the two of us we have over 80 years experience of working on cars. Neither one of us has ever come across such an incredibly highly engineered repair kit for an auto part. You have thought of and included virtually everything necessary to rebuild and install the valve.
