My car is built December 2019 (delivered January 2020).
The ECU as a USB tyce C as a communication port. Not a Mini USD or other kind. So it seems to be like very last model / type / version.
I tried to communicate with two different cables. Both very high quality USB C to C. And in both cases the laptop says it sees the ECU, but can't "talk to it" because there is not an appropriate driver.
I'm not an informatic specialist too, but my guess is that this is about finding a simple driver and download it, or maybe my ECU is one of the very latest and MMC has blocked them somehow that not even the ProTune can acces it?
What really annoys me is that at the dealer's garage tey use an old laptop, with USB A to C converter and they can communicate. But they don't use ProTune but a MMC software.
