I recently bought a 2013 991 S is it a good idea to do a factory reset procedure for the PDK transmission that I’ve read about or leave well enough alone? No problems with it this far.

Yes it is a good idea to do it. It ensures a recalibration if there is any wear.

I have a COBB accessport and when I added the PDK tune, it gave me the PDK relearn capability.

You sit in the car and hold the brake when it tells you to. You can hear it making adjustments.

The car is a bit of a moron for a few miles, until it relearns parameters. But it is a very fast learner.

Its like it doesn’t remember when to change gears until you go up and down the gears a couple of times. But it sorts itself out quite quickly.

It’s good maintenance.

Just to be clear, there are two "resets" that people talk about. One is complete bull****, the other actually performs a calibration that is completely unnecessary the vast, vast majority of the time, especially if you don't have any problems.

There's the song and dance bull**** with turning the car on, turning the ac off, turning the car off, standing outside for 60 seconds, then getting back in. This does nothing -- if you read, you'll find only consumers saying things like "I think it's better!" whereas 100% of Porsche technicians and dealerships say "yeah, no, never heard of that."
There's the clutch wear calibration. This... generally doesn't need to be done. If for some reason you do need it done (jerky shifts, slipping when it shouldn't, after replacing your PDK, etc.), you'll need a tool to initiate the procedure. COBB Accessports can do this, Autel's MaxiSys tablets can do this, Snapon tablets can do this, and of course PIWIS can do this. Call your indy or dealer for this procedure if you do not have access to any of these advanced diagnostic tools.

Be prepared to get told by the dealer that without a problem occurring, running this procedure is pretty meaningless.

I was calling Bull**** on that On off version as well.

Ahh I see why this is BS, you missed an important step. You must spin around 3 times and say the words "Porsche Doppelkupplungsgetriebe" three times correctly for this to work.

Oh, crap. Is that what I've been doing wrong all this time? No wonder!

I'll be damned, I just tried this (in my driveway, with neighbours watching, of course) and it WORKED! My PDK shifts faster, my mpgs went up, I gained 25hp, and I found $5 in the center console!

In addition, it cured my baldness

Porsche_nuts

Mmmmm. Still not working for me! Must be pronouncing Doppelkupplungsgetriebe wrong. Or maybe need to practice my German accent?

Very likely. You need to say it very angrily in order for it to come out right, like with most German. You're spinning around clockwise, right? Unless you're in the southern hemisphere, then you need to spin anti-clockwise!

I hope that people won’t take this seriously because you are completely mistaken. The DIY reset isn’t the same as a full calibration, it only resets the adaptive portion in the shift time algorithm. The rest values are generally more enjoyable and it would have been better if Porsche didn’t even make it adaptive.

i do mine twice a year and the difference is very noticeable.

I also have access to a PIWIS 3 and have done the full calibration. This one will often fail and (as per dealership procedure) requires about 500 ml (+/- 100 ml) of extra transmission fluid to pass. Some dealerships drain it out afterwards and some just let the system evacuate it.

Bottom line, if you tried the DIY reset and it want noticeable to YOU, it’s either you don’t notice it or there was an error in the procedure you followed.

This falls squarely in the category of "consumer did it and insists it works" so please, enlighten us on the exact procedure with quantifiable evidence that anything actually changed. I'll also settle for a vetted Porsche technician confirming the procedure.

Until then, I stand by my commentary. There's nothing about this in the FSM, nothing about it in ALLDATA, numerous confirmations from separate dealers that the song-and-dance method shared around here isn't real, and a complete lack of reputable Porsche technicians even implying that such a procedure exists.


You may be accidentally triggering the throttle adaptation reset, which is real and you can find it under one of the WM 2X00IN entries for DME adaptations in the FSM. Even so, I'd love to see some hard data backing up your claims.

ipse dixit

I mean if people believe that it works, what's the harm?

It certainly isn't harming the car.

It's sort of like that twitchy baseball player who, every time he's in the batter box, taps his helmet four times (2x on the bill and 2x on the dome), grabs his crotch, adjusts his belt, and spits two inches in the front of the plate, before he's ready to take the next pitch. Probably not going to help him biomechanically make contact with the ball, but heck, if he believes it helps, what's harm?

So I went and did this dubblekuppling DIY thingie on my car. It was raining outside, so I did it in the garage, but I struggled a little with the clockwise spinning because my garage is not that large. HOWEVER, I'm happy to report that after doing it - I had to partially lower the windows, btw, for it to work properly - I can definitely tell the difference. My 7MT clutch travel is smoother, the clutch engagement is back down on the floor again, and I swear that the car just looks more satisfied. Even though it's supposed to be for the PDK, I say that everyone with a 7MT should do this regularly as well.
