Repair kit DISA BMW M52TU 11611440049, 11611432557

The DISA actuator, also known as the DISA valve or DISA damper, is installed on BMW M52TU engines. Its main purpose is to control the length of the intake manifold by opening and closing the damper depending on engine speed and throttle position. This allows you to optimize the airflow in the engine and increase its efficiency.

Part codes for DISA valve: 11611440049 and 11611432557.

This set is useful mainly in three cases:

1. The most common is that the valve can break due to the materials used by the manufacturer, such as plastic, and the design of the connection between the lever and the blade. This usually results in a loose connection and unnatural sounds. If the problem is ignored, the vane can begin to dangle even more, and further operation of the assembly will become almost impossible, since the vane can break off and enter the intake manifold, which will seriously damage the engine. The Disa BMW assembly in the M52TU (11611440049, 11611432557) will also have to be repaired or replaced completely, which significantly hits the pocket. Some people end up just removing the vane and driving without it, however, this reduces engine power at low and medium speeds and increases fuel consumption.
2. It follows from the first problem - it happens that the blade is chewed up, and then it can damage the damper, causing air leakage and a decrease in engine power. Repair in this case can be even more expensive than replacing the Disa BMW M52TU unit.
3. There is a vacuum valve in the Disa unit, which may stop working due to a seal failure caused by a rupture of the membrane inside the valve, resulting in the inoperability of the entire unit.

In order not to lead to the need for high costs and lengthy repairs, it is recommended to respond in time to any changes in the operation of the unit and the engine. To fix the early stages of the Disa valve failure in the BMW M52TU, Klifex created a special repair kit that includes a blade and a crank connected by a rod that ensures a secure connection and is the axis of rotation, preventing vibrations.
