I have been lurking since I bought my 2009 Cayman base with PDK a few months ago and have already learned a lot from you guys. I am not new to cars, but am new to Porsche. I am coming from the American muscle and 4x4 world (my main addiciton is 66-77 Ford Broncos) and have a lot to learn about Porsche in general.
 
I have searched and searched and have not been able to find anything regarding the issue I am having so I hoped some of the experienced 987.2 owners could help. Everything has been great  with the car since I purchased it and I really enjoy the car. Over the past few days I noticed the transmission acting odd at low speed. In the morning I let the car warm up for around 5 minutes while I make my coffee and then I slowly drive out of my neighborhood. Just recently I noticed that at low speed and low rpm the throttle will blip (rpms jump 100-300 rpm as it changes gears) when upshifting from 1st to 2nd and 2nd to 3rd. Once I pull out of the neighborhood and accelerate with a little heavier throttle there are no issues. This only occurs at very low speed and low rpm. The car shifts as it should once I give it a little more throttle.

I know the PDK blips the throttle on downshift, but I cannot find anything about a blip on upshift. Hopefully this is normal and I am just being paranoid, as I am prone to be, but any input from longtime PDK drivers would be very greatly appreciated. Thank you for all your help so far and hopefully you can give me some advice on what I am currently experiencing.

Most low speed problems with the PDK have been software related.  Have your dealer scan the car to see what version it is currently running, and update it if necessary.  You didn't say how many miles are on the car, but you could also consider at least a clutch oil change while you are there as well.

Maybe do a search here for “ PDK Reset”. It takes literally 6 minutes and you’ll be amazed by the results. When you read the instructions you’ll think it sounds like black magic but I checked with my mechanic and he verified that it’s a legitimate Porsche procedure. I went through it yesterday and my transmission is a totally different animal.
