Finally got it done - GLK250 DPF/SCR Deleted and EGR disabled
I'm likely going to pull the DPF over the weekend to clean it out. If it's the second item, it appears as it won't be too hard to remove, maybe an hour.




So how awesome is that

1 Little hick! I ask to give back all pieces, and as you notice there are several location where sensor are supposed to be, SAM took them and kept them. Probably worth a fortune for him, and for you if you manage to sell them your self on kijiji like i was planning on.. but he kept them. Probably worth dealing price lower if he doesn't keep them.( 300 - 400 $ lower )
But the job is perfect!
I hit on the highway to jasper(in the mountains), 5.4 and in town around 6.2 per 100k
Bit louder , but really just a bit, No smell at all like previous people mentioned.
I got to say tho. I put on each refill of the gas tank( Diesel additive ). I believe it is damn efficient. 2 shooter glass size each refill, and during winter I use the same white bottle.
Not as mention previously, loooooots of power but you do feel a little more kick.
Since I got it done, I did a reset on the mileages and I'm at 5.9 combine with 2000 more done.
Call Sam. worth a "loooooooots" of headache saving on the long run. I looked at my old bills since I bought brand new the GLK, 2 Pieces already got fixed under warranty in the past and I'm at 103k so far. It would have cost less to do it in the first place when I bought it new and salvage and sell pieces online as used.
So far, no complaint except for little diesel smell. The mileage seems the same, i was expecting to get little better, but it didn't happen. I will do more test once the weather are more stable. The other thing I notice is that I get a lot of white smoke whenever I first start the vehicle. It doesn't really brother me now. I did find a solution for the white smoke by adding the power stroke diesel additive. The best part after the deleting is that no longer needs to worry the emission system fail, like DPF issues, nox sensors fail, def pump malfunction, that really takes the stress off from my mind.
Here are my personal mileage data after deleted
Best mileage ever got: .5.2L/100km (45mpg) - Highway only with 100km speed
Average highway mileage 6.0L /100km (39mpg) - Highway speed 110-120 average
Average City and highway 6.5L/100km (36mpg) - mix between 70% highway and 30% city
In terms of power, I told Sam to tuned down since it was too much for daily driving and I don't like the fact that affected my mileage. If you like the power, DPF delete is the way to go.
Let me know if you need more information
The tecnician just use a software from europe and no electronic welding. For the diesel odor i smell it just the fist 5 minutes when the engine is cold. No black smoke even if i push it hard. The total price 750$ for all.

My car gets better mileage after i completed the engine flush and added ceratec additives. I will do a mileage soon and see if i can get better than 4.8L
From what I've been told, the new software does not turn off any emissions components. It optimizes timing, injection, boost, several other things to make it run much better overall. They do offer additional tunes to deactivate DPF/EGR/AdBlue but those are $100 each. Nice to know I have that option in the future if/when I want to remove them.
What I will be getting is 40+HP and 65+ Lbs/Ft Torque, looking forward to that!
@artim808: I'll keep an eye on the idle rpms before and after, just in case. I assume you had the ECU tuned as well?
