My car is out of warranty as well!
There are TWO vanos sensors. One for each camshaft. Did you change both or only one? I really do not see how a bad sensor could make the engine shake. I suspect you did not use BMW spark plugs bought at a dealer. Or you have a bad plug/coil or fuel injector or carbon buildup. I would start there.
