The electro-hydraulic power steering system is bled automatically when the engine is running. Due to the afterflow in the hydraulic system the level in the electro-hydraulic power steering unit reservoir will fall. After the following procedure has been performed a small quantity of air may still remain in the system. This is not negative as EHPS is bled further during driving.
