The heat will naturally contract the leather, but you need to be careful to make sure the heat is applied evenly, and you go slowly. The Sport Plus seats took about 15 minutes to fix, and the problem never returned. On my GT2 seats, I needed to repeat the process after 6 more months of use, likely due to my worries about overdoing it the first time (the GT2 seat inserts are a whole lot flimsier than normal 911 seats...I'd go so far as to call them cheap). After the second treatment the wrinkles never returned.

Here's an example of a wrinkled seat fixed by simply applying heat...it's a heat gun, so the process goes pretty quickly; using a hair dryer takes longer but removes the risk of damaging/burning the leather. This video lets the heat gun do the work; the "massaging" is my add to ensure the seat doesn't get over-heated and is "contracted" evenly. Scoot ahead to 2:10 in the video for the wrinkle removal (first part of the video is steam cleaning).

ADDED: I’d be leery of attempting this fix with ventilated seats without first removing an insert and determining whether a) there is actually (as reported) a membrane between the seat leather and the foam and, b) if heating the seat from above would damage/deform the membrane in any way.

Pretty pathetic CYA bulletin from Porsche. Yeah, let's blame it on the cow. I agree it's not the leather, but rather the padding.
