Hello all, it has been a while. I have the E44 Varta Silver Dynamic Car Battery 77Ah which I bought in 2016. It died on 2020 January, and I managed to get a replacement via warranty from Tayna. Now today I couldn't start the car due to battery again. I've searched in here but mostly the drain issues were much shorter period. Do you have any suggestions?
I've the Kenwood DNX520VBT, but I thought this unit wasn't the issue and not require any update to avoid drain?
Info: my car is the 56 GTI, stock, and it is a low annual mileage now that it has been our 2nd car since 2018. So car has not been used daily, only twice a week and short journeys too.
