Ask me how I know.
I followed MNIWT's video on removing a MANUAL shift knob. He clearly labels it as instructions for a manual shift, but after failing to succeed by following the VIDA instructions, I tried following his video.
It did come off, but I broke the alignment key on the AUTOMATIC knob. It tuns out that the alignment key is plastic, and if following the MANUAL instructions, the key will be sheared off. Ooops.
It turns out that VIDA's instructions are a little off for my '06 V50: There is a collar below the knob that is shown as being slid down well clear of the knob. In my V50, the collar runs into the shift gate and cannot clear the bottom of the knob, and cannot release the dogs that engage the shift lever and keep it from coming off.
My alignment key is now a screw driven into the plastic in the way of the alignment notch on the shift lever. I made sure it wouldn't interfere with the Park release pin.
