Most every 'bad' story I've read thus far, including the links you
quote, was related to a GM product failure. Hmm. Inferior quality
materials, a trademark of GM products in the US. Another thing common to
many of these 'failures' is the fact that the owners allowed coolant
levels to go unchecked and were found to be extremely low. Boiling
coolant would not be good in any vehicle, no matter what the make or
coolant used.

I've seen the innards of many VW's using Dexcool for the years
(including my own) and there is absolutely no evidence of any problems.

It's also a well-known fact that VWs leak coolant eventually around all
plastic flanges. They warp and crack, then leak. It isn't the coolant
causing this, for sure.
