Thanks for the quick reply!

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!

GLE 250d
Hi there,

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

If you have a Mass Airflow Sensor and you block off the EGR the system will complain that the measured intake doesn't agree with the expected intake.

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.

J'aimerais bien récupérer le 2000$ de Mercedes pour le rappel. Pour ce faire, je dois remettre le tout a l'origine. Le problème est que le tuyau du dpf a été coupé pour récupérer le flange. Il me faudrait donc un autre dpf et je serai en mesure de réinstaller le tout. Si quelqu'un a ca, je serais acheteur.

J'ai ça. Est-ce que c'est une installation temporaire ou permanente.

Dans les faits, Je trouve ca ridicule de tout remettre en place pour que Mercedes les enlève de nouveau pour les remplacer. J'imagine que c'est pour refuser ceux qui ont modifier le système et économiser des $$. Est-ce que vous seriez prêt a me vendre ou échanger votre dpf? Le mien est d'origine mais a un des bout couper.
Merci

Assuming you have the ecu tuned for your delete, you will also need to have it re-tuned to stock configuration to be eligible for the field measure and compensation. That's my understanding.

J'ai acheté un 2e ordinateur non modifié. Je garderai donc mon tuyau modifié ainsi que l'ordinateur modifié si un problème revenait. Je me pose également la question. Est-ce qu'il y en a beaucoup d'entre-vous qui ont été chercher le 2000$ en remettant tout le système à l'origine?

Interesting, I'm assuming the ecu that you purchased has been coded to your VIN?

Non, je pensais seulement changer l'ecu modifié par un non modifié. Selon vous, ca ne fonctionnera pas?

MB ECU's are coded with the vehicles VIN which needs to match the VIN that has been coded to the vehicle security features/system or the vehicle will not operate.

10 year mark update

Hey guys, just want to give you guys a quick update. I still have the vehicle and it almost at 200 km


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.

Thanks for the update. Mine has 203,000 miles (330,000 kms?) with all original emissions in place and no issues (touch wood), runs fabulous. California so deleting emissions equipment not an option.

HI glk fan, I am glad to see this results.
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?

I got mine done in Calgary. You can contact Sam from ECU program in Calgary to get a remote tune. I believe they do a stage 1 tune now with the OBDII

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.
Everything I have read suggests getting rid of the hardware. Who's tune are you looking at getting?

Had my 2013 in for the recall last year, I have the 10 starts until you are a brick message. They replaced a ton of stuff, to the tune of almost $20k and the car was good, but now I am getting the DP error code P203D so instead of trying to get the DEF system fixed, I think I will go ahead with the delete. I really love this car, but the DEF system is a nightmare.

If you had the recall done, that means you should have quite an extended warranty covering a LOT of items, including the DEF system.

Why not let the dealer (perhaps a different dealer?) attempt to fix it?

My biggest issue after the recall is the millage is worse. Went from Aprox 6.5 to 8.6 L combined.

I had not realized that there was such a big warranty on the recall ( 7 years, 77000kms) so I have an appointment to take it into the dealer and see what they have to say. Thanks for mentioning this!

I have not noticed any difference in the fuel economy numbers pre- and post-recall work. I have, however, noticed a difference in fuel economy going from non-winter fuel to winterized diesel.

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?

​​​​​​​Reply to old post... This is the right way to do if you somehow need to delete the DPF. By deleting also the catalyst the car will smell like an old diesel truck from the 80's. The smell will just came after you everywhere you drive. Not very nice and doesn't suite the looks and status of the car. 😁
