It is interesting that the work order indicates that the failure was observed during the service advisor’s test drive. Your earlier posts indicated that you were seeing the failed shifts fairly often. Do you have any tips and tricks for demonstrating the failure? I’m not optimistic that I’ll be able to do “failure on demand” when I bring my car in.

if you have a moment, what did you mean by needing to have the car re-flashed. Oh, BTW, in Sport and Sport+, auto stop/start is disabled and is grayed out on the PCM. If my engine is fully warmed up and I’m at an intersection where I know I’ll be stuck for up to 4 or 5 minutes, I rotate the selector from Sport to Normal to shut off the engine. If I’m driving in Normal, I turn off stop/start from the outset along with selecting sport exhaust, which is always on in Sport and Sport+. Maybe I was influenced by what others said on this forum, but after about 2,000 miles, the engine seemed to free up and the sport exhaust sound got bigger and deeper.

Presumably Porsche Cars NA relies on service department employees to provide feedback on issues and solutions. If you have an occasion to speak with your contacts at the dealership, it might be helpful to ask them to provide feedback to PCNA regarding your repair.

I’m really pleased that your initial experience has been positive and thanks again for giving us an update. I’ll do the same when I have my annual service and presumably the software flash in a couple weeks.
Cheers!

Have had updates, service etc. Hasn't solved it.

Porsche does not yet have an update for earlier cars, but are supposedly working on it.

Several months ago, my Service Advisor said that the car is holding first gear in order to warm up the catalytic converters quickly. I wasn’t convinced and it didn’t make a big impression when I posted it on this thread. But I am wondering if, in order to meet EU emissions regulations/levels, they programmed PDK to prevent short-shifting when cold. If so, the effort to conform to EU regs has resulted in a situation where we are inadvertently revving the engine higher than we would ordinarily want to do during warmup. I guess we should not underestimate the impact of the EU regs. VW won’t offer a manual transmission after 2024 in their Golf and R, and the Cayenne Turbo GT is not available in the EU. I’ll reach out to an SA I know at another dealer and I will be at my dealer next week and will check again there.
