| Description of the problem | I own a 2009 bmw m3. It has the mdct transmission. There is a delay when coming to a rolling stop and then trying to accelerate again. The delay occurs when pushing the accelerator and when the engine/transmission actually engages and moves forward. The delay is as long as 1-1. 5 seconds. This has nearly caused several accidents. Bmw says this is normal behavior, but i don't believe it to be the case. It seems like the transmission doesn't downshift at lower speeds. In fact, only "thinking" and proceeding to downshift after the accelerator is applied. By then, it's too late. As a driver, you expect forward momentum as soon as the accelerator is applied... Not that it down shifts at that point. Plus, the reading display suggests it is in fact downshifted to 2nd gear... But i assure you, that's not the point. This happens every time the scenario is mentioned. Say coming from 35 mph or higher so the vehicle is in a higher gear (5 or 6) and then you slow to say 10 mph and then try to accelerate.... Say in stop and go traffic. |
