Just bought the wife a 21 Q2 35TFSI - yesterday as she was driving the horn activated itself for around 15 seconds - anyone else had this issue - I cannot see a reason it would happen - I have fitted an aftermarket dash cam and used and unused fuse location in the glove box but can't see this contributing to the horn issue as I used a piggy back fuse. I have located the horn fuse in the engine fuse box in case it happens again

Hi,

Welcome to the forum.

It could be linked, so I would disconnect the dash cam for a day or so to see if the horns sounds off again. If is doesn't sound the horn, then reconnect the dash cam and see what happens. If it sounds off again then you can be reasonably sure the dash cam is causing the issue. Maybe a call to the supplier of the dash cam to see if they have had any customers reporting this issue.

Enjoy the car.

Hi,

Control Circuit for Signal Horn
- Open or Short to Ground

03266 - Control Circuit for Signal Horn
006 - Short to Plus

Two codes and no sound at all from the horn. I bet wires are broken. Any idea where horn is located inside bumber?
