Hey guys!
I won't start a new thread since the title of this one matches my situation perfectly.I have a 2023 XC60 PHEV Android (iCup).
I was flashing my custom car configuration, and after the upload finished, the infotainment screen went completely black. Before doing the flash, I checked everything: TCAM was up and running, and I cleared all trouble codes.
When I tried to flash the OEM config back, I got errors on the IHU and CSM modules, so the stock settings failed to install.
I tried to manually reset the IHU and CSM separately, but no luck—the modules were completely unresponsive. That's when a bit of panic kicked in, and I was like, "What do I do next?!" There were no fault codes stored at all! Unhooking the car battery terminal for 5 minutes finally did the trick. The IHU kicked back to life but was glitching hard. I managed to restore the OEM settings, but now I’m honestly a bit terrified of tweaking or flashing anything else.To top it off, this whole mess triggered another issue. Since it’s a plug-in hybrid, the engine refused to shut off, and the fuel consumption "skyrocketed". After about 30 minutes of driving, the engine finally started cutting out, but only when fully stopped—while moving, it just keeps running continuously. It's basically acting like a mild hybrid (MHEV) right now! Even when I force Charge Mode, the high-voltage battery percentage won't go up. I couldn't test plugging it into a charger today because of crazy lines and the heat.I’m completely lost on what to do next.
Has anyone run into anything similar?
