2004 Other BMW Models V12 Front Wheel Drive Automatic 74000 miles

I started my 2004 760Li just fine this morning. Ran it through the car wash and then dropped my son off at daycare. When I started the car again, it sounded a little rough and was very slow to accelerate. It seemed to run a little better at higher speeds but in stop and go traffic, it had difficulty accelerating, sounded a little rough and shifted roughly at the lower gears.

Do you
have the same problem?

Has BMW been involved? The complexity of the car makes it fairly certain that the issue will require more than I can do online and a trained BMW technician will most certainly need to be retained straightaway. It may require software updates and/or reprogramming.

I was afraid you were going to say that. I haven't called them yet as it just happened this morning on my way in to work and was secretly hoping it was a simple fix. I guess I'll make an appt with my mechanic. Thanks!
