PCV membrane n52, n52n, n52k, n52t, n51, n53 11127552281 (11127548196) for BMW

Over time, everything wears out, so this inevitability has not passed and the N52 engine is so reliable in operation. Failure is most often caused by a malfunction of the crankcase gas ventilation valve or kvkg n52.

Membrane breakthrough and consequences

Drying and rupture of the kvkg n52 membrane located in the valve cover occurs. Excess atmospheric air penetrates into the formed hole into the engine, which is not taken into account by the sensors of the consumed air, and the engine start process is disrupted. This is manifested by the instability of its operation, especially in idle mode, as well as the appearance of smoke. In the process of atmospheric air entering the engine, dust can get into it, which settles on its working parts, which leads to their rapid wear.

Testing the presence of a membrane breakthrough

The main sign of a membrane breakthrough is the detection of a characteristic whistle in the area of the oil separator. Which indicates the need to replace the kvkg n52. But the manufacturer offers only the kvkg n52 valve with a valve cover in full assembly, which costs about 30,000 rubles. But you can additionally test the presence of such a breakthrough, for which you need to put a tube on the valve breather and try to blow, that is, blow the membrane. In case of violation of the membrane, the valve is blown freely.

The solution to the problem is cheap and reliable

We offer to purchase the kvkg engine n52 membrane separately, it is much cheaper to purchase, for example, kvkg n52, kvkg n52k or kvkg n52n in full assembly.

Installing the membrane on a bmw n52 kvkg car

First launch after installation

Immediately after replacing the kvkg n52 membrane, the motor will not function quite stably. He needs to be given some work to:

• the fuel cards that were disrupted during the rupture of the membrane were reconfigured,
• the normal operation of the valve has been established,
• the additional air suction was eliminated.

The engine should be turned off after a short period of operation, and then started again, after which it usually goes into normal operating mode.
