Hi everyone.

After taking out my car battery out of the car for 25 hours to charge it at home and putting the battery back in the car no longer starts.

Now I was thinking it lost the key coding or something and one auto locksmith has said it needs security code that comes from Germany etc. I waited for a whole week for him to come back, but the guy is useless unfortunately as he keeps saying I'll come to fix it next day, and the next day etc.

I rang another auto locksmith and he said it might not be the key at all. Please see my uploaded video on how the car is behaving. Audi a6 c6 not starting - YouTube
