BMW 335i DCT Lag

The current M-DCT software in both the 335i and M3 is flawed. It causes a very long pause (commonly called the "lag" or the "lowspeed lag") when coming to a stop or near stop and then trying to quickly accelerate again. The lag is more prevalent when the car is in second gear but also occurs in 1st gear as well. The lag also shows up most commonly in auto (D) modes, but can occur in manual (S) modes as well. The lag is a safety issue, and has the potential to cause an accident. We, M3 and 335 owners want it addressed as BMW is currently in denial mode.
