Hello,

I found different part numbers, but was not sure if the dimensions are different. I am looking to use a DPF delete pipe that was designed for the jeep with similar om642 engine, but test fitted on the ML.

Anyone know if the filters would be interchangeable on the ML and GL in 2008?

Thank in adv.
Steve

Please do not delete your dpf...

Did you find out if the Jeep delete pipe will work on your GL320?

smiledr996s

Not yet,

Hopefully soon, I would really like to increase the gas mileage and performance a little. But mostly since I plan to keep this vehicle a long while, dont like the price of a replacement unit. I am almost to 150k, and my fuel economy is not what it was at 70K. Sure its not helping.

I was hoping to also find any facilities that will clean and test the fuel injectors, to make sure they are also optimal. Although I believe the computer monitors them to a point.

$300 works on both the ML and GL:

Yes,that is the source I had been talking too. He has alot of products for the 2007&2008. He had test-fitted on some ML's but not on a GL. He said he had looked at a GL and it appeared to be the same. I had ordered it and and will see.

why not?

Installed the GDE tune this weekend will take in Tomorrow to see about dpf.

Will update how turns out.

Probably because it increases pollution and the 320's are some serious polluters as is.

I take it as you never owned a 320... I can run it in closed garage for 10-15mins and still be able to breath just fine. Try that with a gasser. I know the difference.

Worst polluters list: http://www.nbcnews.com/id/25516947/n.../#.WOwX3qK1uUk

the Mercedes-Benz GL320 CDI, which is third

Nice. Lean burning, more efficient (24 mpg) is more polluting than some thirsty (14mpg) gas V8. Makes perfect sense. does not match my real world experience.

There is something in common here... These are all gassers.

Though those articles are nice, they do not account for the gross polluter status of the GL320's and that's what this thread was discussing. The top 4 worst polluters in 2008 were all diesels. https://www.cars.com/articles/2008/07/forbes-lists-th/

The GL350 Bluetec's run cleaner but MB is under investigation by the Department of Justice for excessive emissions in the Bluetec's. http://autoweek.com/article/car-news...er-doj-request

It is the fine particles (soot) that are the problem. They are known to be some of the most aggressive cancerous particles known to us. The emission gases of the Diesel engine on the other hand are far more benign than those produced by gasoline engines....

The dpf addresses said fine particles.

a2j

If they were, in 2008, I guess they are not anymore. Oh and btw, VW Touareg V10 TDI years are 2002-2007. So they were taking vehicles from years other than 2008?
Just because you are under investigation does not mean you did anything wrong.
I feel like I'm talking to anti-diesel person who never owned a diesel vehicle. I own both, diesel and gas same year, and I can tell the difference.

I guess emissions and smog rating is not the same thing, as those anti-diesel articles want you to believe.

BlownV8

The 320 is a serious polluter. Period. End of story. Removing the DPF makes it even worse. Diesel particulates, as ALX said, are very carcinogenic. https://www.cdc.gov/niosh/docs/88-116/
https://www.osha.gov/dts/hazardalert...ard_alert.html

I'm not anti diesel at all. I am against removing the DPF filter.

Fourdiesel

from the first link:
"Because of limitations in currently available technology and test methods, NIOSH cannot at this time confidently offer recommendations for environmental monitoring of exposures to diesel exhaust, or for generally applicable control measures that would assure adequate reduction of the carcinogenic risks associated with occupational exposure to diesel engine emissions."
If NIOSH cannot recommend control measures then it is not reasonable to conclude that there is suitable scientific evidence tying diesel particulates to cancer. There is simply not enough evidence - yet. And there may never be.
As I understand the situation, the technology for measuring and identifying particulates of less than 2.5 micron size just doesn't exist. If the substance(s) making up the particles cannot be determined there is no way to identify them as carcinogens (or not). Keep in mind that, at the proposed concentrations, one could breath them every day for a LIFETIME and only accumulate a teaspoon of them in the body. It is very difficult to show a causal relationship of a carcinogen at these very low and distributed dose rates. Many many other bad things happen first.

Maybe you should define "polluter" because I feel like now we are talking about 3 different things.
When it comes down to fixing DPF, I would rather just remove it. Back then, my parents were driving diesels from 80s (mostly VWs) all my childhood and none of us had any cancer or respiratory health issues. I would also not live in LA as well, ever. I think it is all relative.
A few years ago I used to own 2005 VW 2.0 TDi wagon. While it has same smog rating and less emissions than 320, GL is actually a huge step up. That TDi was almost as bad as a school bus. But I would still drive it if it had more seats.

Sorry I did not mean to start such a debate. My fuel economy was getting worse and the always being around turbos. Less is better on the exhaust side. I was unaware how much particles it actually caught.

With the eco tune and dpf delete will say the car drives nicer with smoother acceleration. There is not a noricble sound difference.

I have not not driven far to comment and n the fuel economy. But I think the ecu has to learn the difference.

I also bought a intake pipe that replaces the resonator which is supposed to be restrictive. I will install hopefully next week.

smiledr996s

I really can not say fuel economy is noticeable better at this point. Although I am using the fuel economy values from the display. I am not sure how accurate it is. I should have occasionally figured by hand but my driving patters often vary.


Iwill say that after installing the intake pipe that removes the slightly restrictive resonator
the turbo lag seems to be less.

I have alrhough ordered a sampling kit from black stone oil. I am curious the see how my oil is holding up as well as any things identified in the oil that should not be there

also doing to see what the difference is in the next few oil changes with the modifications

Did you do the DPF delete via the green diesel engineering tune?

They claim the MPG should go up 2-4mpg, which would be pretty noticeable.

smiledr996s

Yes I did. I was expecting to see better numbers on the display. When I called and talked with GDE they made mention the displays are not always that accurate and hand calculations would be preferable.

Would be curious if others using the tune saw better numbers routinely on the display

SFCabs

Any update? I need to go down this road next month but if there isn't any improvement in MPG, then it seems pretty pointless.

Just by removing the DPF regen cycles, there should be a boost in MPG jsut from that.
