Replaced all 4 wheel speed sensors on my wife's VW CC after 2 of them failed and the car was trying to kill my wife. The rear received a different (unnamed) brand and the front received this Autex brand. The front ones are ok. None of the nameless brands worked. No one. Straight out of the box. These AUTEX brands are cheap and my respected German auto mechanic said they would fit. He immediately noticed the problem with the others. Lesson learned.
