Can anybody identify these parts please

[delboy735]

A friend of mine has a problem with her 2001 VW transporter TDi 2.5.
The part in the photograph appears to be loose, and started smoking quite badly earlier today.....not sure what it is though......trying to identify it prior to getting vehicle to garage to keep repair costs down, can anybody in the PH massive identify the part please.









Any help would be hugely appreciated, as my friend is stuck without the van....( Based 20miles south of Oban )

I am pretty sure that's the alarm siren/control box.
