Turbocharger Recirculation Valve - N249-, CHECKING: Function

A Turbocharger Recirculation Valve -N249- keeps a portion of air running through the intake side of the turbocharger when the throttle valve is closed and boost pressure is still present. This keeps the turbocharger impeller from slowing down, reducing turbo lag when the throttle is applied again.

Special tools and workshop equipment required
