ECU beeps @ different volumes at startup????
You know the five or so beeps the ECU gives when you startup.....well sometimes mines beeps fine, sometimes I can only just hear it, sometimes none at all.
Anyone else had this/know remedy?
Cheers

The 480 will beep 5 or 6 times when you turn the ignition if your seatbelt isn't plugged in (and assuming your pressure sensor in your seat works) - to the non beeping people, does your seatbelt-not-plugged-in light come on when you dont have the belt plugged in? If not then thats why you have no beep

the Beep comes from the CEM, not the ECU. Maybe you connected the two contoller connectoprs to the control mode, and you are actually doing (whats left over/or part of the test mode??????)
Maybe else your CEM is getting senile.
This in the worst case. In any other it could be the belt warning, as I understand now some new 480 owners have.

Well I had a failing CEM which started with demist problems... But since you had beeps prior to your problems I don't have a clue what problem might be, sorry.
In any case I hope it isn't your CEM, cause that isn't cheap...

Strange ... the volume of the beeps is getting lower and lower...
A few months ago I could easily hear them (even annoying when using the direction indicator...), but now I can hardly hear the beeps.
I also have the impression that there is more than one beeper, since I hear beeps at different frequencies (am I correct?)
I hear beeps when:
- using the direction indicator
- switching off the engine
- leaving the pop-ups up when switching off the engine and taking uot the key
