Hello! Unfortunately I already have the next problem with my S80. The first part of my (so far rather shorten) “suffer story” I have already summarized in the lower thread. Now the next problem: After about an hour driving the engine suddenly seemed very sluggish to me. I had accidentally plugged in the OBD Bluetooth adapter and could see accordingly that the maximum charging pressure with approx. 0.2-0.3 bar was much too low according to the display. Is this actually due to the AGR, or is this probably just an additional symptom? I realize that this is very difficult to determine in the remote diagnosis, I just don’t want to start wildly swapping if it’s not necessary. Thanks for all the answers and best regards, Alex
