What about reliability up to 160,000 km out of warranty. Is dpf, scr, etc a problem ? I figure these wrinkles should be worked out from euro experience.
Fuel mileage and cost are not the major issue. I just have no local dealer so reliability is important to me. Thanks!

For all it's worth, diesel engines today are not the same as those of yesteryears, aided by better engine, emission, refining and battery technology. In Europe 55% of all new cars are diesel (and yes, I know it includes warm countries like Malta). But more specifically, based on 2012 data (source: European Market Stats Pocketbook 2013
(EU_vehiclemarket_pocketbook_2013_Web.pdf) diesel is well proven in cold countries, specifically BMW. Bits and pieces from the
PDF:
• Diesels sell well in colder Euro countries: Finland (39%), Sweden (67%), ..(pg 88), though tax policy affects behavior.
•
BMW has been proven in the market, with
the largest share of diesels sold in Europe (page 45)
• Emission detail: 96% less than '92 EU standards (pg 8)
Parts of Canada are much colder, and you may need plug-in engine warmers, even for gasoline engines as you well know. My own experience is that diesels are louder when cold until they warm up; and, I had a singular experience seeing a friend's VW diesel started instantly at -25C/-15F for several days in a row, two winters ago.
p.s. you can see pre 2012 data in the same PDF, starting page 90.
Hope this helps.
