07 Bluetec. Is there a primary and secondary fuel filter? - PeachParts Mercedes-Benz Forum

ROLLGUY · #1 09-12-2016, 11:56 AM

My friend has an '07 E320 with the Bluetec, and put a tank of B100 in it. Not many miles later, it was suffering from a lack of power. I changed the fuel filter on the engine, and he filled the remainder of the tank with pump diesel. The car ran much better, but lacks a little power after several miles of driving. I drove it around this weekend (he went away, and asked me to put some miles on it for him), and put eight gallons of diesel in it. It seems to be about 80% now. I am wondering if there is another fuel filter other than the main filter located in the "V" of the engine?

I just checked an easy to use parts listing and it shows 4 versions of one filter. You shouldn't buy it there, but it is a very easy check on parts.

I don't think so. AFAIK beginning with the W211 MB abandoned the two-filter system.

Would there be a tank screen, or does it have an in tank pump like a gasser?

Duh Rich, you should have just looked it up on Pelican before posting! (I just said this to myself).

Just the single canister filter on the 642.

But when I had my infamous gas in the diesel incident (service stations fault) 2 years ago the dealer did remove the tank to drain it.

BTW the oil company insurance ended up denying the claim and I got soaked for $2500. After they told me to go get them fixed and they would cover it. There is a corporate insurance company that is located in a suburb of Kansas City that starts with S and ends with wick. They are b@stards who do everything to avoid paying claims. Including threatening to prosecute me for insurance fraud. Too little dollars to make it worth suing them since it's my word against theirs.

Yes the CDIs do not like B100. Supposedly they should not be run on greater than B5. What do we do in those states with a B20 mandate?

For a long time he would blend his bio with D2 50%. The car (and his other diesels) ran great for years this way. I guess that was okay, but 100% was not.

07 is not a CDI. But to respond to your comment, CDI's do love B100. I have put 147,000 miles worth of homemade BD through mine.

The Bluetec injection system may not be exactly the same as a CDI, but it is very close compared to the system in a W210 and earlier ( no problem whatsoever running B100 in them). Does not both the Bluetec and CDI have a high pressure pump, common rail, and electronically fired injectors?

babymog · #10 09-13-2016, 11:42 AM

I'm not sure if the piezo injectors make a difference.

Have a read of this link below and the link in the first paragraph .
It explains why they only advise b5.
Biodiesel stability and new engines like the BlueTEC - Topic

They only made 4 years of the W210 with diesel for the US market, 96-99. These are mechanically injected engines OM606. 96-97 non turbo, 98-99 are turbo. The pump is computer controlled, they took the sensor and actuator concept from the OM 603 EDS system and used it to control the fuel. The pedal does not connect to the IP directly, you move a potentiometer and that tells the computer how fast you wish to go.

The next time US got a diesel was for 2 years in the W211, 2005, and 2006. These have OM648 first generation CDI engines. Inline 6 cylinder.

In 2007 they introduced the OM642 V6 CDI engine. Available in the gen 2 W211, as well as the W164 (ML), X164 (GL) and R251 (R), and the Sprinter. The 2007 year there was only a passive particulate filter. In 2008 they added the urea injection to the W211 but the ML and GL the urea did not come until 2009. The trademark name for the urea system is Bluetec.

There are many tales of people running greater than B5 in the CDI engines. MB recommendation is no more than B5. I am curious how they are handling the B20 mandate now active in several states.

Thanks for the comprehensive treatise on late model MB Diesel engines. Even though the '07 has no urea injection, why is it still called Bluetec?

First-hand data points...I've been making BD since 2006 for vehicles and home furnace.

83 300SD has burned everything and is still running great. 69,000 on BD, WVO/RUG blend, used ATF, used motor oil.

97 E300D ran 72,000 miles on WVO/RUG blend and homemade BD. Too much RUG blend in NE winter made for long cranking and smoke at startup. Backed off to BD and all was well. Sold car.

05 Blue CDI...147,000 mi on almost strictly BD. All my cars get a small blend of D2 in winter to keep from gelling. The CDI did not like drywash BD when I experimented with it, so went back to water wash and all is well. Over the last 6 years replaced in-tank fuel pump, some weeping/soft lines to/from HP pump, and injector return lines. No other fuel-related issues.

05 black CDI...6,000 mi since purchase, 100% BD.
