can we have more information on the song and its style/singer (male? female? group?)?
how much Turkish was in the song?
I come up with two suggestions which do not really fit to your description.. only in some ways but not exactly..
First one is Anell - Die Widmung a mixture of German and Turkish, but the line stated by you is not in the song.. it's a sad lovesong still

Second one is Muhabbet - Vergebe Mir .. Turkish singer singing the song completely in German but due to the style I could imagine that one mistakes a line or two for being Turkish
