I have Auro OtoSys IM600 pad and Xhorse VVDI2 programmer. Which one can i use for Audi A4 key learn
If your A4 is produced before the year 2012. Otosys im600 can be a good helper.
If after 2012-, i advise you to do it with VVDI2.
So, both Otosys IM600 pad and VVDI2 can learn keys to AUDI A4, depending on the year of the car.
