Wondering if anyone can be of any help to me. The unit I drive, a scania R420 has lost all audible warning sounds. So no indicator, low air, lights left on and hand brake off etc, all are now compelty muted.
Has anyone had any similar issues or know how to sort the problem?
Thanks.
Yes BIG OMMA 
Take the magnet off

It’s an agency setting.
Have a look into the menu system on the dash.
I’ve already tried looking through the menu on the dash. Can’t seem to find anything though.

Why do you always spoil the fun and offer sensible advice
Are you certain you’re not now deaf? 
Oh yeah, didn’t think the problem was my hearing and not the truck

He’s already suffered enough, he’s got to drive a Scania!
If it’s not a setting, then my next port of call would be the fuse box.
Check 'em man, check 'em.

Very true, and it’s not even got the proper engine either
Same thing happened to mine a week or so ago, Scantrucks told me they have fitted a new IMI unit (whatever that is!) and all now working again.
