my name is andre
This is my first post.
If I'm unlucky, I'll have to pull a new cable for the horn.
Berlingo 2 Bj. 2009 Diesel (DV6)
The horn doesn't work, but you can hear the relay clicking. My free workshop said that they had tested the horn alone last fall. Since then we're driving without the horn, but the TÜV is due in the fall

So it could be that the cable is defective.
Anyone have a wiring diagram?
Best regards
Andre
