I replaced my EGR valve due to the insufficient flow CEL.
Good news is that the CEL is gone, and she passed inspection!
Bad news is that for the first 30 seconds or so after the engine starts, the idle fluctuates roughly 100rpm, as well as a mpg decrease of around 3mpg+?
I've only went through 1 full tank of fuel since the valve replacement so at first I though that it may have been my lead foot. But after carefully observing the miles put on, as opposed to fuel consumption per half tank (religiously touch if not exceed 250 miles per half tank by the time the needle moves off of the half full line) I barely got to 230 miles which leads me to think I will be lucky to reach 450 miles to this tank. (normally 500 miles +/- 10 miles)
Am I missing something as far as an adaptation or re-learning a parameter in VAG-COM due to the new valve?
