Interesting.
Owning T1N's I have no problems as long as the NAPA Zerex G05 is available.
I assume that my Operator Manual is the official reference for coolant as it is with engine oil.
MB states that the original Operator Manual is the official document.

BeVo covers our Sprinters as to anti-freeze.
OM6XX covers all of the Sprinter diesel engines to date. 2014 is a break year on the coolant.
The chemistry between 325.0/326.0 and 325.6/326.6 is different.
326.0 325.0 - Si, B - X - Nitrite, amine, phosphate
326.6 325.6 - SI - X - nitrite, amine, phosphate, borat, 2-ethylhexanoic
acid
By the "X" I believe both are inorganic.

It is interesting to note that MB doesn't
require distilled mix water unless your drinking water is hard. That said, distilled water is always the safe choice.

4. Water quality
Clean and the softest possible water should be used for
processing the coolant. Drinking water often satisfies the
requirements. Information concerning the water quality of
drinking water is available from the local water-plant
authorities or the official water utilities on request.
If there is no available information regarding the water
quality or if no suitable water is available, then distilled or
deionized water should be used to prepare the coolant.
Sea water, brackish water, brine and industrial waters are
not suitable. Salts may promote corrosion or form
disruptive deposits.
The analysis values of the water for mixing coolants must
be within the limits of table 5.
