Mercedes-Benz Crankcase Breather Pipe with Pressure Control Valve, part number A6420101791, is an OE replacement designed to restore proper crankcase ventilation and maintain optimal vacuum for the PCV system. This ensures consistent venting under varying engine loads, supporting reduced emissions and protecting critical engine components. The integrated pressure control valve helps regulate crankcase pressure, contributing to smoother operation and improved engine performance in everyday driving.

Over time, the breather pipe can crack or become clogged, leading to oil leaks, smoke, rough idle, or PCV fault codes. Specifically designed for select Sprinter applications, this Mercedes-Benz part delivers factory-aligned engineering for continued reliability and long-term service.
