After looking into this the only thing I can find is a reference to 4,000 mile capacity[0], way less than a TDI service interval. Maybe they mistuned it just so

After looking into this the only thing I can find is a reference to 4,000 mile capacity[0], way less than a TDI service interval. Maybe they mistuned it just so customers wouldn't have to pour a bottle of stuff into the tank, which would have been an awful idea. Or maybe the catalyst they used isn't sufficient to meet US NOx standards with the optimum fuel-air ratio, I guess we will have to wait and see.
