Can anyone tell me how to separate (simply unplug) THIS connector on the MKV Jetta Steering Gear (Rack assembly)? Is the grey piece a lock that comes completely out before you pull the black connector off???? Or do you squeeze (or perhaps lift???) the grey tab and then pull the black connector off??? I have tried everything I can think of using just enough force to not break it, and I'm still baffled. (The other connector below it appears to be the same type , but with a green "tab", and I am powerless to remove either.) Thanks in advance. Any help is appreciated.
