I figured it was better to resurrect an old thread than starting a new one.
I bought a 2010 335d last week. My prior car was a 2007 335i with sport pkg. There is a big noticeable difference in engine braking between the two. My 335i would sort of coast when I lift off the accelerator, but the 335d slows down much quicker. I'm glad it's the norm for a diesel.
I'll post pics of my current and previous cars asap.
