I can't seem to find any info on this. A couple weeks ago my B1 service light came on and when I started my car the horn chirps. Took my car to my local mechanic and had the service done but the horn still chirps every time I turn the key.

Has anyone had this problem? My car is completely stock, no aftermarket alarm or any changes since I bought it.

I thought it was strange that it happened to start when my B1 service was due. I figured I'd ask here before I take it into the dealer as I am no longer under warranty.

Any insight is appreciated.

 

The B1 message just appeared on my maintenance minder today-no horn chirping so I can not help you.
