Sorry Terry, there is nothing listed - yes or no - as to the use of diesel additives in MB diesel engines. In fact, this is all there is on diesel engines in the entire document...
{Start of cut-and-paste from the
Factory Approved Service Products September 2006 bulletin}
Diesel Engines Diesel Engines as of model year 2007 All diesel engines require S15 Ultra Low Sulfur Diesel (ULSD) fuel (15 ppm Sulfur maximum). Failure to use ULSD fuel can severely damage the vehicle’s exhaust after-treatment device. Refer to Product Information (page 14) for a sample of diesel fuel pump labeling.
Diesel Engines - Model year 2006 and prior Use only commercially available vehicular diesel fuel number 2 or number 1 (ASTM D975 Number 2-D or Number 1-D).
As of model year 2005 For information on cold weather operation, refer to the vehicle Operator’s Manual.
Pre-model year 1999 For information on cold weather operation, refer to the vehicle Operator’s Manual or Service Information MBNA 00/7(11-82).
B5 Biodiesel
Mercedes-Benz USA, LLC approves the use of B5 biodiesel (standard diesel with a maximum of up to 5% biodiesel content) in all Common Rail Injection Diesel "CDI-engines." Diesel fuels containing a higher percentage of biodiesel content will cause damage to your engine and are not approved.
As biodiesel can be refined from a variety of raw materials resulting in widely varying properties, the only approved biodiesel content is one that meets ASTM D6751 specification. It must also have the necessary oxidation stability (min. 6h, proved with EN14112 method) to prevent damages to the system from deposits and/or corrosion
Please ask your service station for further information. If the B5 biodiesel blend is not sufficiently labeled to clearly indicate that it meets the above standards, please do not use it. The Mercedes-Benz limited warranty does not cover damage caused by the use of fuels not meeting Mercedes-Benz approved fuel standards.

I would upload the .pdf file (393k), but file size restrictions of this site prohibit it.
