Damn Door locks again!!!!
 

So i recently put a new stereo in my a3 and for whatever reason whether related or not the door locks have gone all wonky. hit the button and only the front passenger and rear driver doors lock now... whats going on here? Any ideas?

Have you figured this out??
 

I just replaced my 2013 A3 stereo and the same thing happened. Any help would be appreciated!
