Blow by gasses, the partially burned fuel-air mixture that slips through the piston rings and into the crankcase, is unavoidable. A properly functioning PCV system protects your Mercedes-Benz from a range of engine issues such as excess oil consumption, engine oil degradation, blown gaskets and seals, oil leaks and an incorrect fuel-air ratio.

The intake manifold operates at a different pressure to the outside atmosphere, creating a natural vacuum. When the PCV valve is open, the intake vacuum draws the blow by out of the crankcase. Of course, that also means that pitar ka lu with the valve can lead to the entire system failing. Most PCV systems use simple spring-loaded valves, usually made of plastic.

In addition to failure with the valve itself, your Mercedes PCV valve may become jammed by a buildup of fuel deposits, locking it in an open or shut position. Stuck closed leads to a build up of pressure in the crank case which creates a variety of oil leaks! And this in turn can lead to a range of issues, including a rough idle. In addition to rough idling, PCV problems with AMG models using the M engine are also prone to other ssues, one of which is squealing noises at idle. The squealing noise is produced as air is being forced out the rear main oil seal on the crankshaft.

One of the most common is a squealing noise while idling, though some owners have reported issues including whistling and sometimes even rattling.

Mercedes-Benz is one of them. And because the PCV system pulls air and blowby gases into the intake manifold, it has a similar effect on fuel-air mixture as a vacuum leak.

This means that unmetered air is entering the engine without the engine sensing it going through the mass air flow sensor and throttle body. The engine control module ECM calculates the amount of air going into the engine through the positive crankcase ventilation PCV system. If the amount of air is more than expected then the Check Engine Light will come on and code P is set. The ECM learns the throttle opening angle and stores it in memory.

If the throttle body is cleaned or adjusted without the throttle relearn process performed, then the code may be set. The fuel mileage may be more than before failure since the ECM will try and compensate for the excess air in the engine detected by the O2 sensors.

Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired.

Code P is a code indicating that the ECM is detecting that the engine has too much air entering and sees this as a vacuum leak.

An engine running with too much air will run lean and cause the engine to run rough and stall at low engine speeds. Code P can be from any kind of vacuum leak in an engine. Some vehicle manufacturers may use different lean codes instead of this code. The code can be generated from a throttle body or idle air control valve cleaning.

This can cause the engine to have to lower the throttle plate to maintain the correct idle speed and see this as excess air entering the engine causing the P code to turn on.
