The battery light indicates no charge coming from the alternator,so it will surely have failed. It could also be the poly v belt having broken, thereby not spinning the alternator pulley but I very much doubt it,as it also feeds the pulleys for the other things like power steering and a/c, and you would have noticed the extremely heavy steering. Depending on how long you ran the car for afterwards the battery itself may or may not be fine. Replace the alternator first, get the battery tested (any decent garage can do this for you) and then the battery if required, but you may have gotten away with it.

Audi A4-how do i know if my alternator is bad or


START engine and turn on head lights to main beam if engine stops and battery is flat then the Alternator isent putting out 13.5 volts or 12volts so then turn off lights and turn on inn and with a test light check power lead on Alternator if you have power to alt then you have either Reg or brush problem .
Take it off and get it tested and if slightly faulty then get a change over one and refit start and recheck your head lights as they should come bright when engine runs evan at idle .
ITS that easy

Battery indicator after new alternator Audi A4


Take it to an Audi dealer. Could have been a bad alternator, and another bad alternator if they didn't use Audi part. Don't use cheap rebuilt Chinease stuff on your Audi.

Battery light stays on until I press the gas


Known issue to occur occasionally on VW/Audi. What is occurring is that the alternator is not spinning out fast enough to start charging, so the light is on. Once you rev the engine, the alternator starts to charge and remains charging till its shut off and restarted. It can be related to too low of an idle (not adjustable, unless you have a dirty throttle plate or air leak), the alternator itself (aftermarket or a bad rebuild) or an incorrect alternator pulley installed (too large).

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.
