No sounds anymore

OK, so when I turn the flashers left or right there is no click-click anymore. When the air pressure is too low it should be a warning sound but is nothing anymore.
I took the dash out and the whole dashboard is encapsuled so I cannot open to see anything inside.
Well, I've been told to replace the whole dash.
Now comes the question:
If I buy a dash from Volvo dealer and I replace it myself do I need the VCAD to program it afterall or as soon I plug the cables I'm good to go?
Coz I prefer to do it myself then pay Volvo one hour labour. But if there is a must to calibrate it after replacing I may have no chance.
Anyone changed it ?

 

Good to know. It was too good to be true.

 

That question was about to jump from here.

 

I just put everything back after I dismembered the dash. I took all the screws and I disassembled the dash till I took the electronics out. Well, bad news. There is no way that speaker can be repaired or such. It is a very weird modern speaker and is all encapsuled. It has three legs that goes into the electronics motherboard and that's it. Nothing to fix or even to see what is wrong with.
I will have to buy another dash. Final answer!
Anyway worth the try. It was instructive.
