Re: New Battery fixes EGR and catalytic converter
Our computerized powertrains have an adaptive learning function and battery disconnection will reset everything. The car will then re-learn certain things over a series of starts, stops, various speeds, etc.This can take a couple days sometimes. Unfortunately, I don't think your problem is solved and that light will return.
What are your codes? Maybe we can help. :)
