There may over time be an improving build quality control in place with greater empthais on the location and security of pipes and fixings,etc. as it would be one of the areas following the radiator failures I would have also focused on at Malvern., when searching for root and potential other sources for the failures. Have there been changes in the eg coolant system filling to avoid air locks.
And I do wonder in the early days of the radiator failures, as to how much the need to prevent air pockets in the coolant and any specialised procedures or equipment was available at the different dealerships when replacing the radiators under warranty.
I certainly noticed a big difference when the software update was applied to my car, done in the middle of December at Malvern, and I immediately noticed the warm up period for the heater to work dropped from 10 to about 5 minutes, indicating the water was being released more progressively and much earlier to reduce thermal shock. Very noticeable change in the draughty Morgan on cold days, much to the wife's and come to that my appreciation.
