My car takes over 5 minutes to warm up when I get off work and it's 34 degrees outside... It only buckles when it's cold... so I just warm up the engine. Even trying to to be gentle on the gas doesn't make the buckling go away... so you just have to be patient with it. It's not good to drive on a cold engine anyways..
As for rev hang problems... or the 3rd gear problem... i've yet to experience it. An 08 Fa5, driven for over a year now.
