ive been having some electrical issues for awhile now. I’m on my 2nd brand new battery in 2 years, my alternator has been bench tested and is fine. After a few months of operation, the batteries need to be jumped to get the Q7 to start. This really went downhill with cold weather this winter (I assume it is related).

A week ago the Audi stopped cranking - I pulled the battery fully charged and tested it - put it back in and nothing. Even though it is charged, the battery level screen says 5% and the dash reports low battery level....any ideas?
