Hi billcyn, did you ever get to the bottom of the horn problem? My MY2007 TDV8 has developed exactly the same issue of only one of the twin horns working. Only one is an embarrassment! I've not yet pulled mine apart to start digging but I'd be interested to know if you found a fix.

Yes, finally bit the bullet & took it to the local Main Dealer who charged £120 to replace both horns. If I'd been 20 years younger I would certainly have sorted it myself for a fraction of the price. So frustrating when you are 80+, know how to do it but the old hands shake so much you can't !!

I know this is an old post...

For the Yank -
Nearside/offside/farside - related to the Steering wheel?

Being a left hand driver from way back in the late 20th Century - Is my nearside the left side?
Do the horns move based on the steering wheel?

As always - thanks for the clarification.

I may have answered my own question...
I don't think the Aux SC Radiator moves - so this would seem to indicate that it was behind the Right Side bumper - universally.
