Does anyone know what 03A8 actually is? Is it a firmware update, a navigation update, or something else?

Its an update for the OCU "Onboard Connectivity Unit" which handles Emergency Calls and Internet Connection for the Infotainment.

Is MU1989 still the latest software version for MIB3, or is there a newer version available?

As far as I know yes. Golf 8 looks like its on 1990

error ERR_01_028_TP

This Error I encountered today as I did a factory reset. With this Error the installation of the digital handbook fails now all the time. Before I wasn't able to log in to my Connect Account for days and the globe stayed after engine start 10 -20 minutes gray without connection

I had the same issue with logging into my account, and I also couldn’t activate the vehicle through the app.

After driving around for a while, the login eventually started working again on its own.

As a last resort, I deleted my account to create a new one. I think that may have caused me to lose the vehicle’s eSIM/data plan.

One question: Is it safe to overwrite the current system with the 7z package? I’d rather ask before I accidentally break something.

You mean the Data you buy on Skoda Cubictelecom? It's a separate account from Skoda ID. Delete Skoda ID account would also kill all your paid subscriptions I think.

Won't work. The only thing that the already updated system runs is the Post Script of all the install positions when u use the same update 1989 files. But maybe someone else knows more.

Yes, I mean the Cubictelecom data plan. If that’s a separate account, then that’s good news. I haven’t purchased any other subscriptions with my Škoda ID (at least not yet 😄).

Maybe someone can share their experience with the proper way to overwrite the latest version?

Or is it possible to downgrade first and then perform the update again?

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?

  1. Press and hold MENU to enter the service menu.

  2. Open Software Update/Version.

  3. 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

Stay away from this update (03A8).
