A5 B9 - Telematics Battery location

[ryno1]

In my Additional Work section of the MyAudi app, it says “Connected Gateway: Renew battery for Telematics emergency electricity mode”now due soon.

Can someone advise where this is located and offer any tips to replacing the battery on my A5 B9 Cabriolet?

I do use Audi Connect, and haven’t had any issues. I just want to keep on top of the scheduled Maintainence.

Thanks

I believe this is under the front passenger seat. The battery is expensive (I have seen a post on another forum saying it is c.£200)
