Hi all,

I'm having a little charging issue with my 2004 A4 B6 1.8T. It won't charge the battery. I pulled the alternator had it tested. It passed. Changed the battery and it was fine for a little while and woke up dead. Jump it charge the battery, works for a while wakes up dead. I changed the voltage regulator with a new Bosch for FCP. still wakes up dead. reading the battery voltage it goes from 12.5V to 13.2 V. Not enough to charge the battery.

Any thoughts?

Thanks!
