Technical specifications

Installation requirements

As this is an electrical engine-management component, installation by a qualified technician is recommended. Allow the engine to cool, disconnect the electrical plug and vacuum or pressure hoses, and replace the valve. Ensure hoses are routed correctly and secure. Clear stored fault codes and road-test the vehicle to confirm normal boost behaviour.

Inspect the connected hoses for cracks or splits, as leaks can produce similar symptoms.

Fitment checks before ordering

The listing marks this item as universal fitment, but it is an engine-specific part. Confirm the OE number on your existing valve and check by VIN before ordering.
