Mk8 remote locking, stereo loosing memory interior light

[apples26]

Remote locking not working but cr real locking on key working

Interior light not working

Noticed it’s loosing stereo settings as in bass rev etc it resets

Are these all connected to a possible daily like the aux battery?

Stripped key batter soldered ok unless maybe battery is kaput


Any advice?

I'd say yes its the first place to look, check if you've got 2 batteries, they'll need drop testing but are 5 years old so.

Was indeed rear battery I put a charger on it and instantly interior lights and remote locking work
