Finally got it done - GLK250 DPF/SCR Deleted and EGR disabled
Glad to hear your happy with the modification.
My wife drives our GLK as well. She really likes the comfort, safety and AWD. I like the fuel economy. The emissions sensors are the only downside of the car and have been problematic.
My understating is MB now in Canada may replace emmisions components due to the problems. I am sure there are more posts on this in the forum (I haven't checked) but my purpose of this messaging was to see if you were happy with the prior tuning.
Glad to hear your happy with it! Thanks again for the recommmendation.
All the best!
I'm not sure which sub forum should I inquire, but I have 2016 GLE 250d with Euro 4 emission, so there's no DPF or Adblue straight from Mercedes Benz factory; there's an EGR though. What's the benefit of closing off or blanking off the EGR or can I turn off the EGR without hardware modifications?
Thanks

The benefit is the engine doesn't have to breath in its own exhaust, so you don't get all those combustion byproducts gumming up the intake tract.
Merci

I still think it a half decent looking vehicle after almost 10 years. Hopefully this year I will have time to black out the rest of the chrome trims
Almost 200k. Hopefully it will get to 300k without major issue
Still gets a very decent mileage.
Recently Canada has a massive recall and settlement on the emission bs. I didn't brother to take the car back to complete the recall. Really don't want the dealership touch my vehicle, special there is nothing wrong with it.
I live in Toronto and looking for somebody to delete everything and install the pipes?
If somebody knows any good place, please let me know.
I like your front grille - where did you get it from?
For the front grill, I got it from ebay.
I did just empty my DEF tank though, drained probably 6 gallons of the stuff. Any bit of weight savings is a win in my book.

Why not let the dealer (perhaps a different dealer?) attempt to fix it?
I once read that the Mercedes DPF is a combined Diesel Particulate Filter and Diesel Oxidation Catalyst (DOC). In systems that have a separate DPF and DOC, the DOC is the first in the stream followed by the DPF. According to that logic, could it be that the upstream section (right, flange side) is the DOC area, and the left the DPF section? If so, would it be worth preserving the DOC (to cut down on odor) while removing the DPF material only?
