It is too soon to tell. Also inline fuel injection pumps are the toughest of the type IPs out there. The rotary pumps like the Stynadyne (Roosamaster) pumps will be the most effected, 2nd would be CAV rotary pumps (though these pumps hold up better then the Stynadyne ones), and the toughest of the rotarys Bosch Ep/VA, VE and Vps.
I CA where I am they have to sell the newer fuel and after 6 months drive shaft seal started leaking on my Volvo diesel with a Boach VE rotarys pump. This pump is similar the VW rabbit pump and VW Rabbits and other older vehicles that use the pump had a rash of leaking pumps. There is at least 2 sellers on Ebay that have a business selling the gasket kits to reseal these pumps due to the leaks.
While the newer fuel will shorten the life of the IPs it probably will not be noticed until many hundereds of thousands of miles have passed.
If you have noticed the leaking IP "O" threads you are probably seening the results of the newer diesel fuel.
Luckly the Mercedes inline fuel injeciton pumps do not have many seals to replace on them.
The newer seal kits are supposed to be made with the new diesel fuel inmind.
