I just did the recall service today with my local Porsche. I dropped it off around 12:30 pm and got it back around 4 pm. Sorry to hear not everyone had a smooth experience:(
I just did mine, super easy! It's literally one screw and I didn't need to mess with the spacers either. DOT sure has the supreme ability to make everything it touches f-ugly and now we have to spend the extra $150 to switch it back. Thanks, DOT.
