I replaced my CCV system. while doing that I had to take the throttle body off. In the Bentley Manual it says when you put the throttle body back on you have to use the BMW scan tool to reset ECM adaptation values. I did not disconnect the plug on the throttle body just moved it out of the way.I don't know why I would have to reset it? There would not be any power going to it with the car shut off while I worked on it. My scan tool for codes does not have a reset for ECM? The car runs fine except for a little less gas mileage on the computer. 1-2 miles less per gallon but, it's winter here
Thanks ahead of time, Steve
