Believe it or not the car fixed itself this morning. I was preparing to go to Autoficina, checked that the indicators were still shot, tried the hazards, which worked, went for the wipers as it was raining, which did not work, then after moving the lever a few times, did work, then I had indicators!
We stopped at Autoficina for a quick check and some advice. They explained that it was probably a dry connection at the hazards switch which is a single point of failure for the whole indicator circuit. The very kind and knowledgable gentleman (who used to do PDIs on Boxers when they were new!) explained to me that you've simply got to keep using all the electrical bits such as Windows and wipes otherwise they get dirty dry connections and stop. Apparently hazards and passenger windows are very common failures due to this lack of use.
Autoficina were very good to me today. Very grateful indeed ( and to Jem for the original recommendation).
So now I am n Epernay in Champagne region, sipping a glass of Brut and looking at our Boxer sitting outside. So far so good!!
