Hello guys,

I would like to ask you for a help with my AUDI A6 2004 3.0 quattro.
Problem I have is just simple - is did not start.

After I turn on the key, LCD panel swith on, everything seems to work, but engine and controlers lights are not light. I have access to simple dashboard menu, checking battery, power radio, but engine part does nothing. Interesting is, when I try activate - for example parking sensors - dashboard notice me to turning ingnition, but ingnition is already turned !

Batery level is on 2 points - about 30-40%, I try to to recharge batery flew times, but it appears like it stuck on that level.

Ingnition switch was changed flew days but without any changes ...

I am really desperate. In past it did it once. I was in service, they told me everything work, but now after flew years same problem came. :/

Thanks for any advice !
