Where is the horn located in the engine bay for this model?/

Hello - we don't have the vehicle in our information. However, it should be on the firewall or on the very front behind the grill. You may have to look under the car. I attached a pic of another 2010 VW pics of that horn location. Also some of the wiring diagrams state left/right front wheel housing and below forward endo fo left/right frame member.
