Radman, I suppose the high upfront costs for both the machine and the "AdBlue" urea will come down with time. I did notice you couldn't search for the additive in the USA, just in Europe... I guess you go to your local MB dealer to get some?
To steer the thread back a bit, everyone who adopts the new tech gets a bit of trouble. What gets me is that the current system for Ford, Dodge and GM doesn't look as good as MB's. I'd love to know why Daimler-Chrysler, soon to be just plain old Daimler, didn't even try to get their system into North America with Dodge. They have plenty of experience with diesels in Europe. Why did we get the dumb system, instead of the "incremental" don't-need-to-be-that-clean one?
