Dead battery only 18 days old

Hello Munith,

It’s probably me, but I’m rather confused unless when you originally posted, your mention of ‘the AA’, you weren’t referring  to the ‘AA’ as most people would have interpreted, but indeed Audi Assist -? as you now mention in your second post. 

Also, you say Audi Assist has taken the car to a ‘repair centre’ - what sort of repair centre?? Surely this didn’t-get-you-home-less-than-100-miles-from-new car should be in the hands of the Audi dealer who sold you this new car - not some (independent?) ‘repair centre’. 
Sorry Mumith, this simply doesn’t add up to me, unless there is more detail - between breakdown and now - which you haven’t yet disclosed. 
Kind regards,

Gareth.
