Left Turn Signal Also Turns On Right Inner Turn Signal

I have a strange problem on my 2015 A3: when I turn the left turn signal on, the right inner turn signal turns on. Everything else works normally. When I turn the right turn signal on, it operates normally. Any idea what could be causing this? Thanks.

I’m sure someone will correct me if I’m wrong but I think the older cars would send the voltage to another lamp if there was a blown lamp in that circuit. Have you check the back and side mirror lamps are working?

Thank you, I solved it! Leuchte17FL R BLK, etc. in the VAGCOM adaptation settings was the culprit. Lichtfunktion B 17 should say "nicht activ."
