Triumph Dealers in South America

Hi my name is Mike and this is my first post, so please forgive me if this is in the wrong place.
I am currently riding my UK registered Triumph Tiger Explorer in Argentina. I started in Buenos Aires and am currently in a campsite in Rada Tilly headed for Ushuaia. After that, who knows.
I was contacted by my UK Triumph dealer today, who told me my bike has been recalled by Triumph to have a new Electronic Control Module fitted.
My question is, does anyone have any experience of Triumph dealers in South America, the good, bad and indifferent?
I need to bring in to my thinking that at some in the future I could build in to my trip a visit to a dealer, but I’d like to know which one to aim for.
Included in any info you have would be whether the dealer speaks any English. I can get a beer and a pitch on a campsite, but my Spanish is going nowhere with getting a new ECM fitted under warranty.
My access to WiFi is patchy, so if you have been kind enough to respond and I have not replied, it is simple that I‘m off the grid.
As an aside, my travel blog is at 2wheeltravels | Mike's trip to South America.
Many thanks for your help

 

Thanks Steve that's really good of you.
i'm OK with where the dealers are. I'm really interested in finding the ones with a good reputation to do the work. I don't feel like I have to go to the closest, so I'm looking for a good one which i can build a visit into my trip.
Any extra info on the recall would be gratefully received.
All the very best
Mike
