This has happened to me twice so far. While driving in Sport Plus on a spirited drive about an hour into the drive manual mode stopped working both in sport plus and sport. The paddles nor the gear shifter would not work in manual mode. After stopping the car and turning it off and getting back into the car turning it back on. It worked fine again. Has anyone else encountered this?

 

Yes, happens to me every so often. I drive around town in sport and manual and for no apparent reason it just moves to automatic and stays there until I stop and restart the car. I mentioned it when it was in last week but it isn't fixed by reflashing the PDK as it already happened on Sunday.

 

Very odd. I drive exclusively in manual mode in sport plus and have never had this happen in 20k miles.

 

I think it's a protection thing the car does to guard potential damage from over heating etc..

 

Hi G
What wheels/tires and mods? Can you figure out a pattern to it?

 

Hmmm. When drifting the car for long sustained periods (like a couple minutes) I've had the PSM turn itself on and not let me turn it off again unless I stopped the car and restarted it. But I've never had the car prevent me from being in manual mode. That sounds like something else to me.

 

I had this problem on my panamera once . I was racing , wanted to downshift and I couldnt go in manual mode , no matter if I downshifted with paddles or stick. The problem didnt repeat since than. I think its a glitch or overheat . No problem since than .

 

I don't see how it's anything to do with overheating since I never am running the car hard when it happens. I am of the opinion it's a software issue somewhere. Turning the car off and turning it back on is the only thing that fixes it.

 

WRS with your current mods have you ran it in the quarter yet? Sorry if I missed it.

 

Well only at the county road so far. The last trip to SAR I ended up with a failed diverter valve. I also have a new map for Stage 4 that I haven't gotten to run on the new tires. I did get a 10.4 @131 at the county road with a 1.55 60ft using my Stage 3 map on the Stage 4 hardware. So it's still a work in progress but I am now below 10.5 ET. That was on pump gas. This morning is perfect county road weather but I have a workout in an hour so I can't go today, maybe tomorrow morning.

 

That is awesome, i love these cars. My next car is definitely a used 991 Turbo S.

 

I see this once is a while because we play with different wheels, tire pressures and big power so much. If the car sees inconsistent traction or rolling calculations it will default until you cycle the ignition. It's the PDK related side most likely. Some cars never do it. Some cars do it stock with 21' wheels. It's random and you may find a pattern or reasoning.

 

Interesting because I do have 21" wheels on the car????

 

If you don't want to list mods or anything feel free to give me a call I'll try to share what I can to help out!

 

No worries here is a list of mods thus far:

H&R Lowering Springs
21" 3 piece HRE Wheels Classic 300 series
IPD "Y" pipe and plenum
AWE Intake
Tubi Catless Exhaust
GIAC Stage 2+ Tune

I'm interested to hear your thoughts, thanks so much.
