What owners say
Check Engine Light - Code P052E71 - Positive Crankcase Ventilation Valve Performance. The component failure can lead to increased exhaust gas emission, oil leaks, and internal engine damage resulting in unsafe operation. Yes, the problem has been confirmed by an independent certified service center. This specific vehicle has not been inspected by the manufacturer, but this specific problem has been identified in other similar Mercedes-Benz years, make, and models. MBUSA LLC is only willing to apply the EMISSION EXTENDED WARRANTY to certain models within a certain model year, even though the design and engine components are nearly identical if not the same. My vehicle is the same model year and class, but a different model type and not included in the EMISSION EXTENDED WARRANTY. Repair cost can be in excess of $2,000 if not covered under the added warranty.
There was a recent extended warranty issued by Mercedes-Benz to repair certain vehicle models free of charge that have a check engine light code P052E. Unfortunately my vehicle (2015 CLA 250) was not included in that recall, but the CLA250 models have the same issue and run the same risk of safety being compromised. Now myself, and many others, have to pay a hefty out of pocket price for a malfunction that is strictly the fault of the manufacturer. Please look into this and strongly consider having Mercedes-Benz include the CLA 250 models in this warranty.
The component that malfunctioned is the Crankcase valve. This valve malfunction has caused issues will the car is idle. The issue has been confirmed by the dealership. The issue has been inspected by the manufacturer as the manufacturer has released extended warranties on other models. The malfunction causes the check engine light to come on, however in the past it has gone off before a diagnostic test could be run; the check engine light would come on and go off then go on and go off, the exact amount of time is unknown.
Engine light come on at about 43000 miles. Code scanner is p052e. Upon research is a common problem with Mercedes and approximately $2000 dealer repair.

Blow-by gases are mixed with oil mist and other contaminants that can harm an engine's internal components and contaminate the environment. How does the crankshaft ventilation work- When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft) that pulls gases out of the crankcase. To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap. the engine misfires, you may have trouble getting your vehicle up to speed. Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on the accel INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),
