Repair kit for BMW N46N

The engines of German cars have always been distinguished by power and reliability. But some models still have vulnerabilities. For example, the valve cover on the N46N has a rapidly wearing element.

The crankcase gas ventilation membrane may burst and crack during operation. The breakdown of this element is usually accompanied by a number of extraneous sounds when the engine is running. Whistling appears most often. This breakdown occurs when using valve covers such as 11127555212.

How to fix this problem?

The Bavarian automaker assumes that if the crankcase ventilation valve breaks, the owners will buy a new valve cover entirely (for example, 11128645888). Therefore, separate membranes for BMW N46 KVKG are not sold. Although such kits are very popular, because the engine of this type is installed on many models.

If the valve membrane is not replaced, fuel consumption will increase, engine elements will wear out faster due to contamination, as well as the operation of the electronic control unit will be disrupted, and the fuel card settings will be lost.

We produce repair kits for BMW N46, which help to quickly and easily fix such a breakdown. The kits include parts of our own production, completely identical in shape and composition to the spare parts of the German automaker.

The kit consists of the following elements:

• valve cover;
• membrane;
• spring.

Any motorist can use the kit. To do this, the cap of the KVKG is removed on the valve cover under the number 11127553171, -7555212 or -8645888. Quite often, in case of breakdowns, it can collapse or not be removed normally, so we have provided a spare part. Then remove the remnants of the old membrane and the spring. Replace them with new elements.

After tightening the cap, start the engine. At the first start with a new membrane, the motor can work unstable, make strange noises and keep the revs unstable. This is normal, because the electronic control unit has already tuned in to the excess air in the engine during the period of use of the broken valve. Now, with the new membrane, it will rebuild the fuel cards to normal operation.

Let the engine work a little so that the ECU has time to update the data. After the second run, all failures should disappear. Your car will work like new!
