A slightly bizarre but real world tip for those people considering going for the heated PDK steering wheel........Don't do it. I must admit I went with this option as it was relatively inexpensive. But when we had the cold snap recently, the top and bottom sections heat up with the pdk button section still being cold. If you're driving it in auto mode then it's ok but if using manual/buttons you don't get the benefit! Out of all the options I spec'd this one was the only one I'd give gladly return to Porsche! Cheers!
