So, I'm ready to tell you how it all ended. In fact, the problem really was with the HPP. Both the first and second Bosch dealers had never handled this procedure before. The next day after reviewing the material, I went to the same dealership and asked them to look into the HPP. Another employee was already there, and I asked him to do it, but he rather rudely said he didn't have time. Incidentally, after my first visit to the Bosch dealership, I got a service reminder in the Bosch app. He specifically installed it for me so that I would come back later. I asked him to remove it, but he rather rudely tried to deceive me, saying that it couldn't be removed and that I needed it. Although we all know that this is another Bosch ploy to pay for nothing. In the end, without receiving any help, I went to another dealership, where in 20 minutes and €35, they activated the port. By the way, I asked them to remove the service reminder, and they kindly did so.Please let us know how it goes there may well be others here, including me, that run into the same problem and it will be good to know if the HPP is the issue.
