2004 Audi A6 Quattro V8 4.2L
Hello, my problem started with my key not working. I change the battery and still wasn't unlocking the doors. So I sync the key by pressing unlock and them put the key in the driver side door and turn it counter clock. The key started to work but then I've notice that the flashers does not flash when I lock or unlock the doors via key. Then I go in thecar, turn it on and press the hazard switch and nothing happen. I turn the lights on and the hazard switch lights up but flashers still not working. I then signal left and right and both sides work. So overall my flashers to indicate that I lock the vehicle is not working nor does my hazard lights not working, but signal lights work. Any suggestions. Thanks.
PS.....I'm a new Audi owner. Please don't criticise me on my lack of knowledge lol.
Thank you

There is coding is 46 for central lock confirmation but I'm not sure if you have a 4B or 4F chassis.

If the button lights up but they do not function it's more likely a fuse or relay.

Post up a complete Auto-scan and that will help, but check fuse per manual as well.
