Repair kit DISA BMW N51, N52, N52N, N52K 11617522928, 11617560538 small blade

In modern BMW car engines, a special DISA unit is used, which is mounted on the intake manifold. This is a vacuum mechanism controlled by an electromagnetic valve that responds to signals coming from the ECU of the motor. And this unit fails pretty quickly.

DISA's work is based on a scheme of separated pipelines. Let's try to explain what this means. So.

What is the DISA block for?

To regulate the flow of air entering the motor, it is redirected through pipelines of different lengths and widths. To do this, a special flap is used in accordance with the current operating mode of the motor, blocking some pipelines and opening others. It, together with the mechanism controlling its position, is the "block" of BMW DISA.

The meaning of the functioning of this node is the instant redirection of the air flow through pipelines with different cross-sections and lengths. This is how the characteristics of the airflow directed to the motor are adjusted.

If the motor is running at high speeds, the air is directed through wide, shortened pipelines, and at low and medium speeds, the flow is directed through long, narrow pipelines. This ensures a constant amount of torque at any operating mode of the motor.

Problems with the DISA block and solutions

During the operation of the machine, disa e83 (on this brand, and on others with similar motors) fails. This happens gradually, the reason is the connection and the material (plastic).

The connection of the blade and the lever is such that it gradually loosens, the rigidity of the connection between the parts is lost and a situation arises when the blade randomly dangles, while making specific sounds: buzzing and even cracking.

When this happens, it is recommended to stop using the car and do repairs. Otherwise, the blade will come off completely, which will cause serious damage to the motor.

But removing the disa n52 and replacing the worn-out block with a new one will solve the problem for a while. The plastic in it is the same and the connection to the lever is exactly the same. And a new block costs about 5000-6000 UAH.

We have found a solution.
