750i Idle Smoking
Hello to ALL!!!!

I have read many of your post, in regards to the 2007 BMW 750i, having smoking issues. First, let me say very good reading and awesome information. I am experiencing those same issues and battling the idea of purchasing an extended warranty ($3700+) or getting it fixed, out of pocket. I really like the car and don't want to part ways with it.

Any suggestions?

white smoke means that you are burning oil and may the sign of failing valve stem seals. Using seafoam may clean them off and restore them. I would suggest putting the seafoam in the oil and driving for about 20-50 miles and then changing the oil. Repeat with cheap dino oil and repeat 2-3 more times.

i have the same problem gents...but with mine i get a small puff of smoke after 4000rpm.its a once off puff until the next time i start my car.
