Ok so i have an audi 2009/12 ( The old Model)
The car have no problem , on Tester no error , but i replacement the old battery with a new battery after the old battery Dies.
So when i put the key on contact it says Battery week (But the battery is new).This is one problem
The other problem is the car don't start , when i put the key incontact and try to start it dosent working( So when i try to start it just revs on automat but don't start like i dont have battery) (I'm in winter so i was thinking the fuel freeze but this is not the problem.
What can be the problem ?
