Have the knob installed in my Seat Leon 1m and was skeptical about the reliability. The most important during installation is probably the tight fit of the control box. When Leon is under the shift boot much foam, until I had placed it there, the gear indicator was very inaccurate. Today I attached the box using an angle on hard plastic, the display now has a 100% accuracy! Horny Gimmik, albeit not cheap :-)
