I was offered an OTA update (Download 03A8) on my vehicle. At the time, I didn’t have an active eSIM/data connection, so the download stayed at 0 MB. I eventually cancelled it. Since then (over a week ago), the update has never been offered again. After that, I performed a factory reset on the infotainment system, hoping the OTA update would reappear. Since then, the system attempts an installation every time I perform a factory reset, but it always fails with the error ERR_01_028_TP. The original OTA update (03A8) is still no longer detected. Has anyone experienced this issue before or found a solution without having to reflash the unit at the dealer? I also have a few questions: Does anyone know what 03A8 actually is? Is it a firmware update, a navigation update, or something else? Is MU1989 still the latest software version for MIB3, or is there a newer version available? Can I simply reinstall MU1989 in the hope that it will fix these errors? Is MOI3_EU_SK_R9890L MU1989.7z the correct firmware package for my MIB3? Is this the correct procedure for a manual update? Press and hold MENU to enter the service menu. Open Software Update/Version. Start the update from the USB drive. Should the .7z archive be extracted before copying it to the USB drive? Approximately how long does the update take? Is it recommended to connect a battery charger, or is it sufficient to leave the engine running during the update? Thanks for help
