745li puff of smoke after idling at redlight
Help!! I get a nice puff of white smoke after sitting idled at a light then hitting accelerator
aggressivley. The shop stuck me for 600$ after going in and pouring some chemical solution into the air intake manifold, (they said the code led them to bank 1 airflow issues)
the chemistry was suppose to remove the supposed carbon buildup inside the manifold.
This didnt fix the problem and check engine light still came on. Also the exhaust smells really rich like its not burning exhaust properly.
Thanks in advance..
