Left my daughter's house and car showed a bunch of faults: auto shut off disabled, sport mode disabled, no reverse, then went into limp mode. It was hot out and I had it in the sun with top down for a while. Thought that for some reason the electronics got over heated from sun exposure so the next morning after it cooled down I pulled the codes and got P1735 and P1731 (which I can't find an explanation to). These appear to be PDK faults. I reset the codes, started up and so far have had no problems.
