last year in southern France my transmission failed. i was finally recovered and taken to a local garage who ordered the necessary parts. They didn't arrive and didnt arrive and didn't arrive. Finally after 9 days i got this french garage to give me a photocopy of a 3D part with part number that was required, and then i took it to a local computer shop who emailed my local somerset garage who ordered these parts for me and had it couriered to the campsite i was at. Courier cost was £45 - well worth it. This took 36 hours from my email to somerset to the the parts arriving in France. By the time the English parts arrived the french parts also arrived the same day - so i had the french parts fitted and on my return to Uk, the somerset garage took back the parts and got the money back.
Apart from the 10 days hanging about (which was the fault of the APPALING recovery service i had paid for via AIB - and who then wrongly told me that it would cost $3950euros to take me to Cherbourg!!!!!!)
I realised that i had to think laterally if i was to get home and so i came up with unusual solutions.
i had earlier been taken to a Mitsubishi main dealer who had categorically told me after TWO test drives that there was nothing wrong with the tranmission and my van was perfectly fine....... but then it was 4.00pm on a friday - they didn't want the job.
i'm not telling you this to depress you, but to explain that lateral problem solving may be necessary..
Have you checked your
insurance and your recovery ADAC paperwork ? The recovery call centre staff i spoke to handled recovery calls on behalf of many policies and some staff were useful and gave me totally wrong information about what cover i had. If necessary you could also talk to the English branch of the ADAC HQ. Make an official complaint if necessary. You need someone on your side.... fighting for you - someone who knows the full details of your product who speaks English and French.
I have discovered that some recovery programmes are just that.... and they dont actually do roadside repairs - they just recover you (but only where there is good access) and take you to a garage for repairs. The best thing you can do is what you have done - ask for personal recommendations for a garage so you can be taken to a good garage.
Christmas complicates things... i know... and dont forget most businesses close noon-2.00pm every day.....
