Well, I missed this thread. I am glad so many called BMW on this issue. I think I had the first MDCT in Texas back in May 08. My car also had this issue and I can completely identify with the OP. Pulling out into traffic making a slow u-turn and nothing happens when you hit the gas. Well, that combined with BMW service frying my original tranny by changing the "lifetime fluid"...I sold it after 3K miles and am now waiting for the 2014 to come out. Long wait yes but I am gone overseas much of the time. Happy all of you are driving without the lag now, the car was an absolute thrill when everything was working right which was 99.9% of the time! Cheers.
Crying is for babies, little girls, men who have just had their ears ripped off, and men who have toasted MDCT's due to service errors.
