Battery light in 2006 Audi A4 keeps coming on.

I just replaced the battery in my 2006 A4 when the battery light came on based on the Audi dealer's recommendation. Unfortunately, 2 days later the battery light came back on again. What could be wrong?

The battery light coming on usually indicates that the alternator is not charging you can check it yourself if you have a volt meter,it should charge between 13.8 & 14.3 volts ......hope this helps.....cheers

Audi A4 airbag light came on after a battery failure. What needs to be done besides go to the dealer?

Low Battery voltage at B+. You had the ignition on when battery was low causing self check in SRS system to default off and set a code.

Needs Audi/VW compatible scanner to clear the code.

Battery dies on 2003 A4 audi

HI there,

I had the same problem with mine. Managed to determine that it was the rear brake light switch that caused a short. This meant that once the car was turned off power was being drained. We thought it might be the computer module shutting down which can take up to 10/30 minutes. But No. Replaced with a new Brake Light Switch, Problem Solved

Battery light keeps coming on as i drive i have replaced the battery and the light glows bright the minute i go near or over 3000rpms my headlights start going bright and dim and the car feels like it...

Possible problem with the voltage regulator. Call an Audi dealer and ask if that's a separate part or if it's built into the alternator. If it's separate, you could replace just the regulator. If not, you'd have to get the alternator.

Another outside chance is that the load reduction relay in the car is getting screwy, and that may need replacement.

It's to the passenger side of the battery, near the base of the windshield. You'll see two metal pipes coming through the main firewall next to the battery. The recharge port is on there.
