[C320-list] no starting noice

[Robert Seastream]

On our 2002, I've found that sometimes twisting the black plastic  
grille covering the 'buzzer' right or left (thus tightening or  
loosening it) will temporarily fix it.  This 'buzzer' is really a very  
small speaker (piezo element aka 'coil' driving a plastic diaphragm  
aka 'speaker cone'), thus I think that sometimes the grille expands/ 
contracts with temperature changes and prevents the diaphragm from  
vibrating.  A test to confirm this would be to substitute an external  
buzzer for the original; I've not done that yet.  While I don't ignore  
the gauges and buzzers, I tend to rely more on my ears (engine  
noises), and nose (engine smells) as monitors.
