Battery failure in Audi A3

[Graeme D]

I have just been informed that the two batteries in my A3 need replacing. The car is only 4 years old, and the 48v battery is particularly expensive. I would have thought the life of a £1000 battery should last longer. Can I ask if this is considered standard, or is this a part failure? Any feedback would be interesting. Thanks in advance.

This seems unusual but also not surprising when you look at similar failures with other ev batteries and motors.

Welcome Graham and thanks for joining,

Was this car registered in late 2020 rather than earlier in the year? 
If so, could, just could, be the adverse affects of cars sitting around for months awaiting components/ Covid associated. 
Kind regards,

Gareth.
