In the US, there is enforcement at both the federal and state levels, which would impose massive fines on companies providing EGR/DPF Delete services or the operators who have the work done to their trucks.

Need proof of enforcement? Look no further than a $500,000 fine levied by EPA in January against Edge Products, an American company that sold more than 9,000 devices allowing owners of model year 2007 or later diesel pick-up trucks to operate without their factory-installed diesel particulate filters.

GLEM This is going to sound random but I've been looking around online for at other diesels and what not and people are deleting the DEF system. Has anyone thought of that?

Mac In any event, based on what I've read it seems to me that the amounts stated in the service invoices above seem too low. A Cummins diesel FAQ says the "DEF dose rate will vary slightly amongst engine manufacturers. While most engines will have a dose rate of 2% of diesel fuel consumed, the dose rate will range from 1% to 3%." Even at a low dose rate of just ~1% I'd be expecting to use 3-4 gallons of AdBlue over the 10K service interval... or, about 1/2 tank of DEF, not 1/2 gallon.

Mac .
FYI-- in addition to the above, found the 30.3K service invoice too. It says... AND ADD 4.0 QTS ADD BLUE FLUID.

The 2015 ML (GLE) AdBlue tank is 7 gallons and, apparently a lot to spare...

We've got a 2015 "250" with 47005 miles and prepaid service and it does get better mpg than our previous 35OBTC so it probably uses a bit less AdBlue every 10K miles.

The 40k service invoice says, "1/2 GAL OF ADD BLUE." Ditto for the 20.5K service. The 10.4K service says, "//CORRECTED ADBLUE LEVEL. 4 GLS"

So, I'm thinking MB's little diesel uses ~1/2 gallon of AdBlue every ~10K miles and the 7-gallon AdBlue tank is only filled with 3-4 gallons to begin with (or, perhaps 0.4 gallons were added at the 10K service).

With the DEF filler cap under the fuel door next to the green fuel cap, I'm not expecting any problems after the extended service that I paid for in advance is all used up... I will still be taking my rig to the dealer until the 100K extended warranty is used up. Having twin turbos and piezoelectric injectors, I did want the added security but now I'm spoiled and so far it has been been easy, problem-free driving for us (knock on wood). The miles between fuel stops is great and not having any problems with the DEF tank going dry between service intervals is part of the package: e.g., >30 mpg on a 5,000 lb. SUV with exhaust that passes the white handkerchief test.

Benzinator If the DEF level drops below the reserve level, you should get a warning and still have time after that to refill before it goes empty.

GLEM If it's anything like other systems, like Range Rovers for example, you'll get multiple warnings until the eventual "no engine restart" to which I'm pretty sure you better have some DEF on hand because it really won't restart.
