Hello all I may posted this thread in the wrong area first....
I posted it in electronics, I usually read and till today did not really have an issue so if I screwed up sorry
I replaced my battery in my 2002 A6 2.7 T and now the center display is not showing the diagnostics at start up and when I hit the menu button underneath the windshield wiper arm the menu is blank for the diagnostics but yet the mileage menu is fine it also displays open doors and such
any ideas? i had a problem with the radio on the last battery replacement and that was an easy fix
