Clicking noise behind air bag

I have an 03 360 Coupe and occasionally while the car is running, I hear a electronic clicking noise coming from the area behind the passenger airbag. It sounds similar to a higher pitched click that is produced by the turn signal. It clicks at a random pace and sometimes just goes away. Other times, I turn off the engine and the next time I start it up, the click is gone. I may not hear for days, but then it resurfaces for no particular reason.

I have tried running the car with the AC system off, same thing for the radio, but no luck. It doesn't sound like it is a short in a speaker wire, but I am having the car checked by a stereo shop this week while installing a new sound unit.

Anybody have any ideas? Do you think anything harmful is happening?

Speaking of the turn signal, has anyone tried to change the sound of the turn signal indicator? That ngalk, ngalk, ngalk sound is very un-Italian.

 

FerrariLou, did it happen even when you did not signal to turn? Did the dealer fix it, or did you do it yourself? If so, where did you get the part?

Thanks for your help.

"Curly from the 3 Stooges made that same noise, Ngalk, ngalk, ngalk!"

 

FerrariLou, it appears you have solved the problem for me - this FChat stuff is great.

I'll get into the fuse/relay panel in the front trunk tomorrow and see if I can isolate the clicking noise to the turn signal relay. If that is the culprit, Ricambi has the part for $170.00 #164369.

Thanks for your help.
