Kit for removing EGR, heat exchanger and vortex dampers BMW N57 from 2008 to 2012

In BMW cars with N57 engines, an exhaust gas recirculation system was originally installed. It works like this: the exhaust gases from the outlet of the manifold are sent to the heat exchanger and pass through the USR valve. After that, they enter the inlet. This is done in order to reduce the amount of nitrogen oxides that are emitted into the atmosphere. Simply put, the principle of operation of this system is to redirect the exhaust gases into the intake.

But there is one significant downside. Due to the constant circulation of harmful substances in the manifold, the level of oxygen in the air-fuel mixture decreases, and engine parts become twice as dirty. As a result, engine elements quickly wear out and fail, and the design itself will quickly become unusable.

German BMW manufacturers install intake manifolds with swirl flaps on engines. Over time, the higher the mileage of the car, these dampers begin to wear out and become non-functional, and also cause many problems in the engine. That is why you should use this repair kit manufactured by our company to dismantle the EGR system, heat exchanger and swirl flaps. After carrying out such a procedure, you will notice how the power of the car will increase significantly, and fuel consumption, on the contrary, will decrease.

Set composition:

• 1 manifold outlet plug.
• 1 intake manifold plug.
• 1 fixing bracket. It is used as a plug in a hole that has formed in the cylinder head.
• 2 plugs for the coolant circulation channels of the heat exchanger.
• 1 plug for swirl flap shaft.
• 1 adapter that connects the heat exchanger hoses.

Stages of dismantling the EGR, heat exchanger and swirl flaps on the N57

The recirculation system in the H57 engine includes several components. Also, from the exhaust manifold to the intake exhaust gases enter through the heat exchanger and the USR valve. After removing this system, it is necessary to block the following openings:

• In the intake manifold from the valve.
• At the outlet of the manifold.
• In the cylinder head, to redirect antifreeze to the heat exchanger.
• In a block that serves to drain the antifreeze from the heat exchanger.
• In the cylinder head through which exhaust gases enter the intake cooler.
• In 2 hoses from the inlet cooler.

All these holes are closed with the intended plugs from this kit.

How to remove swirl flaps.

First you need to remove the intake manifold. Then you need to get the axle, because the dampers themselves are built into it. Next, remove the lever that rotates this axis. Where the shutters and the axle are connected, you need to wipe with kerosene. This is done to make it easier to remove the axle. After that, get the frames and remove the flaps. You also need to clean these frames and the intake manifold. The frames must be mounted back, and the resulting hole is closed with a special plug and fixed.

Having done all these steps, you need to assemble everything back and make the firmware.
