SOS Module Problem

[Gadjet]

Hi,
My Wife's 2021 Polo Match has got an erro messeage popping up about the SOS module.
I put OBDEleven onto it and discovered the telematics ECU had two error codes: -

Code: Select all

        B1916F2 - Backup battery flat
            static
        B1916F4 - Backup battery Service life critical
            static

Does anyone know where the ECU is located, Google gives me three different locations so I was wondering if anyone else has had this issue or knows where the ECU is.

Thanks,
Phil

Just so if anyone else is looking for the same thing, it was located behind the main infotainment display screen right up under the top of the dashboard.
I found the location in the inline workshop manuals found in links on this forum.
