Whenever slowing down to a near stop, the engine will randomly stall. This can occur at anytime, but is more likely to occur when the outside air temperature is in the 90's or above (it will stall in cold temperature as well, but not as often). The engine temperature at the time of the stall is always completely normal, the car is not overheating in anyway. It is also more likely to occur in "sport mode". This issue only effects BMW e89 3.0 automatics. An automatic should never stall. Once the engine stalls you are forced to stop the car in order to restart to move. This issue is occurring world-wide. I have taken the car to the BMW dealer in austin, tx to look into this issue. They stated that there were no error codes present in the computer. The check engine light is not on. I had a BMW shop foreman drive with me and we reproduced the engine stall as we approached a stoplight. …
