There can be other times the horn sounds. When what proved to be my Boxster's passenger side door lock assembly was going bad the horn would sound when locking the car like something was open/ajar. I suspected it was the switch of the console latch and would open and close the console lid and this quieted the horn. But this behavior would appear again and again. Only after the door latch assembly was replaced did this behavior go away.

Update replaced the K & N Filter and cleaned the MFS , but CEL came back on in about 200 miles. This time it only showed P1123 code. Reset CEL and ordered a MFS. It has come in and the Light has not come back on for about 300 miles. I going to wait and see how long it takes to come back on before installing the new MFS.
On the horn sounding on locking. As suggested it was just a trunk lid that I had not been closing.

Its been about 600 miles and the CEL has not come back on. Looks like cleaning the MFS has fixed the problem. Must have been the K & N filter oil on MFS.
