Toyota Aygo 2005-2012. Toyota Auris 2007-2009. Our custom built state of the art HIL (Hardware In-the-Loop) testing rig allows us to run these actuators under real-world load and driving conditions. Once all internal faults have been identified our technicians will rebuild the actuator and replace all common failing components with versions that are higher rated than standard, and then extensively re-test to ensure that no faults remain.
