Since I am not yet an Audi specialist, I now ask you for help My question now: Is there a board computer to upgrade? And if so, how would the cost point approx. BZW what do I need to do with it, or is everything already available. It’s important to me that I have my temps in mind, and the average consumption is displayed to me.
