 Quite a common problem cars Audi, VW, SKODA, SEAT - damage to the membrane, which is installed in the cylinder head cover. Through a ruptured membrane, air enters the engine that is not detected by the mass flow sensor, this makes the engine difficult to start, it is unstable (especially at idle), there may be interruptions in the ignition and, of course, the Engine may get dust, which increases wear details and mechanisms.

If you hear a whistle in the area of ​​the valve cover, then the membrane is torn.
The fact is that the manufacturer sells only the cylinder head cover assembly, we produce and sell this membrane separately.
