Audi Canada has sent out recall notices in April 2024 for B8/2013-2015 RS5 vehicles. They are classifying this as an Emissions Recall 37P1 and state they will update the ECM and/or the TCM. Little detail is provided other than saying a software error may result in elevated tailpipe emissions when driven in Sport Mode.
Gee, you would think it would be allowed a little “extra” in Sport Mode.
So, what would you do if it was your car? Mine is still all factory tune still, and if you read my earlier post from last year, I do still have this regular idle surge/hang that I wish would go away… what’s the chance that the revised ECM update might include other tweaks found in the intervening decade?
