Description

Wastegate Modulator for the turbocharger boost control system.

This electro-pneumatic solenoid valve is controlled by the engine ECU and regulates the pressure signal supplied to the turbocharger wastegate actuator. By modulating that signal it governs how much boost the turbocharger develops, keeping charge pressure within the mapped target across the engine’s operating range. A faulty modulator can result in over-boost or under-boost conditions and associated fault codes.

Specified for the Td5 2.5L five-cylinder turbo diesel engine.
