When I wanted to push the 718 PDK by hand about 15' in my shop, I couldn't. Hold light = not on. Brake light = not on. PDK in N. Can't remove key with PDK in N. Tried to push with key in Acc. and Run positions. Tried to push forward and backwards. When trying to move car by turning the left, drivers side rear wheel I can hear a clunk when the wheel rotates a couple degrees. The same sound occurs when it is in park so I assume it must be in park even when the PDK said N. If I can't move it how would a tow truck driver load it? Just drag the non turning rear wheels? Help!!
