Spot on as always Dave. I had a call from yet another Australian 2011 owner with a car that is supposed to have had the "fix" but it has failed now as well. Same again for another owner a few months back.
Great shame but there is more to come on this issue I suspect...
I think that your timing was unfortunate Oz. 2011 was the bogey year for the leaf spring problems and that's something I also faced with Bumble. Maybe I should have pressed MMC for replacement springs but it made more sense at the time to get some 4 Seater springs from Mulfab, on recommendation. If I had been facing dealer fit prices I might have thought differently.
Let's hope things improve.Even glacially!
