2nd 997.2 Annual Service
So I got my 2009 C4S serviced at the dealer on Friday after a year. I had anticipated doing it every 7,500 miles, but the year creeped up before the mileage. I did the first service at Porsche of Stevens Creek after driving to CA for the Historics last year. This time it was done at HBL Porsche in Tysons Corner, VA. Besides the usual items, I also had my PCM 3.0 updated to version 1.4. Of note, I reported to them that I had an unusual hesitation leaving from a stop and going from 1 --> 2 (my car has PDK - where's ADias? 
).
They reported that they also observed the issue and found the following fault codes in my PDK:
P1990
P1991
If any of you guys know what those codes are (and their relevance), please feel free to chime in. I know I can google them (and I will), but you guys seem to have more info than just the code reader. Additionally, they reprogrammed the DME control unit, reprogrammed the PDK control unit, and performed the "Torque Loss Adaption" and "Throttle Adaption".
Long story short, my car feels like a new one. I was getting tired of PDK, but this helped fire me back up. My service advisor also suggested I drive it a little harder...
Price out the door was $395.80.

Chris glad you got that done. Will have to take mine in sometime soon. Am not at 1 yr yet. Purchased Jan 2010 and only at 6000 miles....you think it would be worth it? I may need to ask the dealer down here in Texas to see if he has any updates for my car. Ya think?

Had PDK software update, the change points seem to happen at higher revs now. It also refuses to go into higher gears, where it dictates to too low revs, including manual change. My fuel consumption has not changed interestingly. It feels better at normal (not sport or sport plus) mode.

Guess I'll have to take mine in as well. I've been driving exclusively in manual mode to avoid some the PDK "indecision" issues that I've noticed over my year and a half of ownership. Not really been an issue since I do prefer the manual mode, but I would be interested to see if an update made the auto mode any better. Thanks for posting.

Well, I took mine in last week for a TPMS issue (turned out to be user error) and was told there were no new PDK software updates. My car was an early 2009 build and last at the dealer in December for first annual oil change. I did get the latest PCM update 1.4 (even though version still only shows "V"), so who knows? Guess I'll ask again in December when I'm back for the second oil change.
