Mercedes says goodbye to diesel in North America | Driving
Basically says that diesel fuel currently and in future available in USA will ruin our modern diesels and will void warranties.
Is it true that B5 diesel is not widely available? This is what article claims:

Most fuel stations in the marketplace sport a blend of diesel fuel and biodiesel, the ‘bio’ being derived from a plant base or recycled oil. Mercedes-Benz requires owners to use diesel with less than 5 per cent biodiesel, called B5. The problem is that many outlets throughout the U.S. offer diesel with up to 20 per cent biodiesel – B20. This higher level wreaks havoc on the engine, leading to expensive issues not covered by warranties because people have used the wrong fuel.

This is what MBUSA says:

Quote:
Mercedes-Benz USA approves the use of B5 according to ASTM specification D975 [Ultra-Low Sulphur Diesel (ULSD) with
a maximum of up to 5% biodiesel] in all Common Rail Injection (CDI) and BlueTEC® diesel engines.
The only approved processed biodiesel for B5 blending is one that meets the ASTM D6751 specification, to prevent
damage to the engine and fuel system from deposits and/or corrosion.
The use of diesel fuels containing a higher percentage of biodiesel, (B6 to B20) according to ASTM D7467 as well as
straight biodiesel (B100) according to ASTM D6751 may cause severe damage to your engine and fuel system, and are not
approved by Mercedes-Benz.
The Mercedes-Benz New Vehicle Limited Warranty generally does not cover damage caused by the use of fuels that do not
meet Mercedes-Benz approved fuel standards.
