New to Diesel, Glk250 EGR/DPF Delete?

Hey guys, I recently pulled the trigger on a 250 after three months of searching for the right color/options/price. I ended up with 2015 with 19k miles on it.

Ive read about common problems people experienced, and Id like remove the egr/dpf system completely. Since it'll save my engine from unnecessary soot buildup, while increasing MPG. Also saving a few hundred in long term adblue refills wont hurt.

I hear its illegal, but I don't need to get emissions checks in my situation.

after hours of research on the these forums, I see you can "turn off" the egr/dpf system through ECU reprogramming but is a physical delete recommended?

And if so who has done it or have the know-how?

Thanks

I wouldnt do it until you are out of warranty
It could be a real can of worms otherwise
There may be a problem with resale later
I cant see the advantage of a delete unless or until you are faced with a component failure

If the benefits are achievable by doing the deletes, I would never get rid of the car, so resale would not be a problem.
I read on the diesel forum about a guy with his bluetechGL opening his manifold to find caked up residue from years of use and regular maintenance.
That drained some of his power and efficiency.

id like to avoid that seemingly inevitable fate, assuming the process is relatively safe/easy.
But Youre right, I would never do it under warranty

Seriously? Do you really do this on such a new vehicle? I have 2010 GLK 220 CDI, 171000 km on it and no problem (knock-knock) with DPF or EGR...

Im just trying to find information on how to do it. this will definitely be something i would do to my car later on.

Of course I wouldnt be doing it anytime soon, im still under warranty.
doing so now would certainly void it.

I dont know how diesel laws are in Norway, but the U.S is quite strict. much of europe embraces diesels, I dont see any reports of how bad their air is
But anyways, why wouldnt you want to get better performance from your vehicle??

EGR would be considered a contributing factor, but not a cause of soot. The cause is soot forms during combustion in-cylinder and a portion of the gases slip by the rings and down into the engine oil. An engine with high blow-by could lead to increased soot in the oil, but in general the bluetec engine is quite dirty. Turning off the egr reduces soot a little but changing the pilot injection, main injection and post injection is the most effective method to reduce soot.

Doing this delete/injection mod after the warranty expires is generally too late. if you can't do deletes, change the oil more often.
