It's not? Are you outside the US? It's helpful to list your location. In the US all MB CDI's 2007 or newer are Bluetec.

This from Popular Mechanics, July 2008: Their SUVs and crossovers, the five-seater ML-Class, the seven-passenger GL-Class and the six-seater (with an option for seven) R-Class, now get the option of a 50-state-legal diesel engine: the 320 CDI Bluetec.

This car came from Florida (with 8,000 miles on it) and did not have the Bluetec option, but it's still very touchy emissions-wise.

But, I appreciate all the information and will be looking into what's up.

I'd suggest draining your tank and replacing the fuel filter immediately. You've already proved B100 is too much. Continuing to burn it will possibly do further damage.

If it continues to run poorly, you should take it to the dealer to have it scanned with SDS. They can see MAF, 02 exhaust and other data which will help determine what was occuring at the time you lost power. OBDII scanners wont provide that info.

I don't see any non-Bluetec E-class diesels for the 2008 model year:

Which engine does yours have? The inline 6 or V6? What does it say on the trunk lid?

If you do decide to go to the dealer, make sure you don't have any bio in your tank, even traces of it. You warranty is intact unless they find out you ran bio or bad fuel.

Mercedes only recommends a maxium of B5 Biodiesel in any of there engines. I have seen a '07 GL320CDI completely shut down due to biodiesel. I wouldn't ruin such a nice car just to try to cut down on emissions....ULSD is clean enough!
