They are for any car. We are specifically discussing the 2011+ w/ DCT tho.
I bought my car used. It had already had the SIB done. The listed SIB is specific to DCT. I don't think it is part of a general software update.
That said, I still found it was hesitant from a stop but did not have idle issues. I had the PPK installed via coding and it's fixed. It honestly transformed the way the car drives. Smoother, better, faster.
