Had a strange fault on my 2013 981S the other day. Came to the end of an uneventful motorway drive, stopped at the roundabout on the junction and as I pulled away I could tell something wasn't quite right. (Not usual for the PDK to have to change down two gears to accelerate from 65 to70mph!) A mile or so later, on pulling away from another r/b, I got two warning messages " PSM disabled" and "Auto stop/start disabled". Anyway, it turned out that the brake pedal pivot includes a plastic bush that is a bit tight and can get sticky when it's warm. This means the brake pedal can stay slightly depressed without you realising it. The PSM cuts out because it thinks you are braking and accelerating at the same time. Fortunately it was fixed quickly under warranty. (Thanks also to PC Tewkesbury who helpfully diagnosed the problem and advised I could drive back home to Solihull if I kept the footwell cool and was prepared to pull the brake pedal up with my toe should it stick again). Both dealerships confirmed (obliquely) that it's a known problem.
