Vacuum Modulator Renault Duster 149567084R

The vacuum modulator with part number 149567084R is an OEM electronic vacuum solenoid valve used in Renault Duster diesel variants, especially the 1.5 dCi (K9K engine). This component plays a critical role in managing the EGR (Exhaust Gas Recirculation) system and turbo control by regulating vacuum pressure to actuators.

It ensures optimal combustion efficiency, reduces emissions, and helps maintain smooth engine performance. The valve works by controlling the flow of vacuum signals to the EGR valve or turbo actuator, allowing precise adjustment based on engine load and driving conditions.

This part is commonly found in Duster models from 2010–2018 and may also be compatible with other Renault/Nissan vehicles using the same K9K diesel engine platform.
