New Battery wont hold charge
A4 B6 130 wouldnt start a week ago, checked battery and it was the original Audi part, so thought its time to change.
Bought a new Bosch S4 fitted and all was fine when I drove it daily, parked it Friday and left it till this morning (Monday) and when I started it the low battery (brake symbol) came up and it sounded sluggish when starting.
Hoping someone can recommend me a few things to check, so far I need to:
Check the black box on the positive terminal
Check alternator cables arent corroded
Check if Hazard light stays on
Check battery voltages when running and not running
Can you guys think of other checks I need to do?
Thanks in advance
