Evening ! Bit of research in behalf of my mate who races slalom discipline with a 106 GTi . He has issued with the PAS steering rack binding/locking . Since the type of the race asks for loads of fast steering movement lock-to-lock , the binding/locking issue appears while turning the steering wheel sharpish from one to another side , say by steering to the left and in the need to quickly change direction ie. steer the car to the right side - the steering wheel binds/locks . My guess is something to do with the PAS cylinder maybe locking the rack because of the increased pressure build up inside the cylinder due to the friction while spinning from one to another side fast and for a longer time period than usual as it is in road use . However , apart from race use , this car is also his daily drive so he wants to retain PAS system as it is . Anyone knows what really causes this problem ? and is there any kind of modification which can be done to eliminate this while retaining PAS system ? (if the PAS system/components after all are the ones to blame for this binding/locking) Thanks ! D
