iStep rewind back to 2016
Hi there, I have updated most of the ECUs on my car to a 2020 iStep version, however this has broken the ASD (active sound design) on my car. I have tried various things like coding it to the vehicle, making sure the set up is matching to the car but nothing has worked. I think I need to put the old / original firmware back on to it, it's F20-16-03-504, does anyone have the right CFAD file they can share with me and how I would go about putting it on, or does anyone know what version of pztdata that I need in order to get this back to the older version? Thanks in advance,
