He actually showed me a You Tube vid of it. But it wasnt an official BMW vid, but he said it worked the same way. I'll have to see if I can find it.....
Another thing I asked him is how come the 330d 0-62 is less than the E90 335d. He couldnt answer and kept going on about how engines had improved etc.... twin scroll turbos....etc... In all fairness I dont think they know a lot about it as its so new.
