While at the dealer today for service on my 2010 E64 I mentioned a roughness or jerky behavior when driving away from a cold start. My SA promptly replied this is "normal" and they all do it, larger displacement engines are the worst. All BMWs with either auto or manual trans display this- making it normal. Declaring a fault "normal" somehow makes this OK? None of my other four (not BMW) vehicles ever exhibit this jerkiness which in any other situation could be fixed with just a little more "choke" equivalent. How come the vaunted engineers can not figure how to smooth the running of a $100k car? Is there an easy fix?
