hello. my audi a6 has a very strange issue with the battery. it works all good. but sometimes (it happened like once or twice a week) the battery dies while driving. all electrics dies. only the headlamps works. then i drive for a while (about 15minutes) then all the electronics just turns back on and it works fine for a while. the battery charges to 100% in the MMI after that.

the reason why i cant figure this out.
i bought a brand new battery before this summer, and it never happened again, until now! the same issue occurs.

 

no one ever had problems with battery running empty while driving?

when the battery says 100% in the MMI when you start the car. then runs empty after a short time while driving.

and when its runned empty it loads back to 100% in the MMI after like 10 minutes.
