Had my vehicle in for state inspection and a required vehicle check maintenance reminder , I
was just informed by my CA that they have to keep the vehicle overnight for additional programming for emissions, I just had the update to the EGR valve done about 2 months ago, my vehicle is a March 2011 build, has anyone else had this " updated" software done, Of course they had no real information on what this is.
I have had luckily no check engine lights at all in 25k miles of driving.
