The Crankcase ventilation valve called (Crankcase Rebreather)comes with a defect making engine light to come on after about an average of 50.000 miles, with a code p052e, preventing passing state vehicle inspection. Feedback from many Metris ownership highlights exact same challenge with engine light turned on at all times. But dealership is charging up to 3.000 dollars to remove their own faulty designed part.

CHECK engine Light CEL Code P052E suddenly turned on in the winter about 1 1/2 year ago, but turned off itself after a month. The Check Engine Light CEL code p052e turned on suddenly in June 2024 and stays on still. Emailed and complaint to Mercedes Benz USA and received no answer. MERCEDES BENZ USA given recall and Emission extended warranty on this code to all C, E, G, , SLC And SLK Class passenger cars with 2.0 Engine on August 25, 2023, but excluded my passenger van model, Metris, which has the same code and is a common problem. This is not right and not fair. Please advise and help.
