So noisy how do you get at it want to put a little foam around it to keep the loud clinking down Sounds like deep in middle of dash???

 

You need to pull the speedo and put something over the holes on the back of it so that it reduces the noise as there is no relay to quite down this is all done thru computers and the sound is generated by a speaker.

 

I hate to suggest the obvious, but have you tried going into the radio's setup menu and turned the "signal" volumn down? Schatzy's right, the turn indicator noise is computer generated and has it's own volumn control.

 

The Gong adjustment does nothing for the turn signal sound.

Here is a thread that goes over all of the details on the turn signal sound.
