Description
Electronic VGT turbo actuator replacement for DAF XF 480 and XF 450 Euro 6 trucks, fitting the PACCAR MX-13 12.9L and MX-11 10.8L variable geometry turbochargers. Replaces the Swiss-manufactured 06426554 / 6426554 unit. Die-cast aluminium housing with CAN J1939-15 smart control (TYPE 11), E13 Euro type-approval and US EPA 10R-06-16115 certified. Must be calibrated after installation.
Details
This is a complete electronic VGT actuator unit, not a repair board or PCBA kit. It contains a DC motor, reduction gear train, position sensor and integrated control electronics in one sealed housing, driving the turbocharger unison ring to move the sliding nozzle ring.
This aftermarket replacement actuator is supplied as a direct replacement for the original Swiss-manufactured 06426554 / 6426554 unit fitted to DAF XF 480 and XF 450 trucks. It is designed to match the original travel calibration, gear ratio and connector layout, so it installs without modification.
Fitment note: DAF XF 480 is powered by the PACCAR MX-13 12.9L engine (353 kW / 480 hp, 2500 Nm), while the DAF XF 450 uses the PACCAR MX-11 10.8L engine (331 kW / 450 hp). Both are Euro 6 inline-six common-rail diesels with variable geometry turbochargers. Because MX-11 and MX-13 use different turbochargers, always confirm the engine family from the engine type plate before ordering.
- The DAF XF nameplate stayed the same across generations while the turbocharger changed. The Euro 6 XF generation (MX-11 / MX-13) covers roughly 2017 onward, and the New Generation XF / XG / XG+ arrived in 2021 with revised cab and aftertreatment. Verify the VIN, not just the year and horsepower.
Every unit is bench-tested before shipment. As a J1939 smart actuator it must be installed and then calibrated with a compatible diagnostic tool following the engine manufacturer procedure - an actuator that is not calibrated will not control the VGT nozzle.
Important Fitment Warning: smart J1939 VGT actuators may look identical but are internally calibrated to a specific turbocharger vane geometry and stroke. Do NOT order by vehicle model or by appearance alone. Match the number stamped on your original actuator and confirm the turbocharger part number before ordering. A mismatched actuator will set SPN 641 FMI 13 (VGT actuator out of calibration) and the ECM will disable VGT control.
