per the title, this is ridiculous. 99/100 times I put my car in reverse, and with my foot on the brake, i slowly back out.. about each full turn of the tire, the car shakes and shimmers, like it is starving for gas, or misfiring.
This DOES NOT happen in gear.
Now, while pulling up to a stop light, when I finally come to a complete stop, it does one last shake and shimmer, almost like a final downshift so to speak. It also kicks down sometimes rather roughly.
I've notice, recently, now, that i am getting the roughness while at a stop light, no movement, just sporatically.
I have used Shell, Mobil, Chevron and Citgo Premium gases. I have varied stations, and times, and this is consitant. it does have a couple of good runs, and maybe a decent day here and there, but by and large, this is prevelant ALL THE TIME.
Has anyone had this, or have it, and is there any solution? family and friends are shaking their heads at the car... with me, the 5'er's have been one thing after another.

Mine does both of what you mentioned, although less so since I had the software update. I am embarrassed anytime I have to put the car in reverse when my wife is in the car because she always says whats wrong with your 70k car? Yours being a 2007 model should already have the 21 CIP update.
irony is that it isn't a cold start issue. it is an all the time issue! your wife is right (as always)... what's wrong with our $70k cars?

Sorry that you have such severe rough engine issues.
Have you removed the charcoal filters? If not, take them out and see if letting it breath easier helps.
I sometimes get the cold start rough idle in reverse. And once in a while I get a bit of engine burst / final gear change surge when coming to a stop, but only after a cold start and only for the first stop or two.
Both of these symptoms feel like minor stutters to me - I never feel like "OMG, what's wrong!" These are not full-time occurances for me, and neither happens after the engine warms up.
This does seem to be a common complaint, though. Besides some others here who have noted this issue, go read a 7 series forum and you will see that 750 owners say the same things.

I agree ewwith tachyon, try removing the charcoal filter. its designed to trap gases and send back into the engine. I have only experience the roguness in the morning when the car is cold only. The last CIP 21.xx upgrade solved 90% of it at Pembroke pines BMW and the filter mod i did solveed it completely...so bottom line seems your car needs air and a cip upgrade..another way is to take it down I75 to about 150mph and that should clear out the engine
KIDDING...before i get flames on it
KIDDING...before i get flames on itDon Juan.. i have the 2007 and it should have come with CIP 21. this is an ALL day occurence with me. it is not OMG.. but only to the extent that is DOES happen all the time.

The problem I see with cars like ours is that there's SO MUCH that is controlled by software, and we know how unpredictable software problems are - how software just gets corrupted for one reason or another. My 550i was built in January so it has CIP 20 - so they said.
Post a reason/solution if the dealership looks at it and determines what it is. Good luck.
