Finally got it done - GLK250 DPF/SCR Deleted and EGR disabled
This is the website information from my local tuning shop - ECUprogram in calgary
I have been a forum member for a long period of time. Somehow i forgot my user name and password to login whenever I tried to make this post. Anyway, I have seen many members asked if it possible to get the GLK DPF/SCR/EGR delete in the past. Recently, I have found a tuning shop in my local area and completed this modification. To begin, I would like to show the website that I found which makes me super interest and exciting about this modification.
So for the price of $1099 CAD i can have a stage 2 tune and increase 60 HP and 40 TQ?!?!?! Yes that is correct for the tune! But you have to get the DPF delete kit, which is $799 CAD and approximately 5 hours of labour to install the DPF delete kit. The total cost for me for this modification was about $2,500 CAD. But man! the difference of the power and how the vehicle perform was day and night!
First of all, my GLk250 currently at 115000 km. I did not purchase the extended warranty which is another factor that pushed me to complete this modification. I had my DPF filter replaced at 50,000km under the factory warranty. I also had my NOX sensor replaced at 60,000 km, again, under the factory warranty. These two repairs always makes me worry about the cost for the long term ownership for the GLK250. According to the dealer invoice, the DPF replacement was about $4,000 CAD and the NOX sensor was about $800. There are no way I can afford these kind of expansive emission repairs and I do love my GLK250 and planning to keep to drive for a long period of time. So ever since then, I have been doing a lot of research and see how I can deal with this problem.
During my research, I found a lot of diesel truck owners and VW jetta owners completed a DPF/SCR/EGR delete. But unfortunately, I cannot find any DPF delete information regarding with our GLK. Hopefully my posting will help the fellow GLK owner if they decide to proceed with the DPF delete. I called around in Calgary area and see if any shops willing to do a DPF delete for my GLK. There were multiple of them informed me that there are no dpf kit available for my GLK and most of the shops are not familiar with Mercedes. Until I found Sam from ECUprogram! Oh man! He is like a diesel expert! He told me is possible to do it, but he never worked on a GLK before. Like I never met a mechanic that is honest like him. He told me he was able to help me delete my DPF and SCR, disable the EGR valve, which makes the modification is completely reversible whenever I decide to sell my vehicle.
After the modification and tune completed, my GLK feels like a brand new vehicle with lots of power! It almost feels like the break is not good enough the for amount of power. It getting late at night now. I will post more pictures tomorrow! If you have any questions about this modification, please don't hesitate to ask me. I learned a lot about he GLK from this forum. Now i believe is my time to give back. Cheers !!

I read this with mixed feelings. On the one hand the emissions system on these diesels is expensive, complex, susceptible to failures and chokes overall performance. On the other hand it does keep toxic emissions out of the air that we breathe.
I commend you technical achievement and condemn your added pollution.
You must not have to face regular emissions inspections where you are.

I sympathize with GLK S-F regarding the high cost of potential emission control components. I believe those items are covered by the emissions warranty for 7 or 8 years. The emissions warranty is not same as main warranty so no need to buy an extended warranty to cover those items. https://www.mercedes-benz-burlington...benz-warranty/. I once had the main computer on a smart car replaced under that emissions warranty.
I don't know about Alberta, but in Ontario, cars are emission tested once they are 7 years old. Most are done by just using the OBD2 data. (all but 1 sensors must be "ready") But there is also a preliminary inspection to check for modifications. Wonder if the tuning modifications make the OBD data look like the car has no problems?

I used live in ontario for over ten years and i know the emission test you talking about. Whenever I did the research for DPF delete, i saw more shops offer that in Ontario than in Alberta. Although there were more shops offer dpf for the trucks in alberta, just not so much to choose from for the GLK.
Whenever I did the DPF delete, SAM told me that the diesel engine cannot be tune by OBDII. Sam said the reason behind is to make it more complicated so makes harder for people to mainpulated the emission sysmtem. During my research, i found a guy that sell chips in Ontario to overide the emission components, but not true DPF delete. If you give a search in KIJIJI, you will find it.

Hi,
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

I purchased my car about 3 months ago. During this time, the glk250 have spent more time at the dealer than on my driveway. I'm going have this done to mitigate all the headaches associated with this car DPF, and Adblue property. I have a few questions for you. Any help are greatly appreciated.
1. Is it possible to just have the DPF delete kit without having the stage 2 tune or is it all or non and not a la carte?
2. Did they have to fabricate some parts for your exhaust after removing the Catylic converter and such?
3. Did they end up removing the DEF tank or is it still in there and just not functional?

Hi OP. Thank you for the info you provided in this thread.

2) The DPF kit is bolt on and completely reverse able. If one day you decide to sell the car, all you have to do is pay labour and reverse the DPF system
3) No, they did not remove the DEF tank. Mine just sit there. If you want, you can get it remove, it just a lot more labour.
If you have anymore questions, I will suggest you contact Sam @ECU tuning in Calgary. They are really good and knowledgeable in terms of our diesel engine.

1) I dont think so, because you will have all sorts of engine code after you delete your DPF. You can get a tune close to the factory setting , like similar power and torque.
2) The DPF kit is bolt on and completely reverse able. If one day you decide to sell the car, all you have to do is pay labour and reverse the DPF system
3) No, they did not remove the DEF tank. Mine just sit there. If you want, you can get it remove, it just a lot more labour.

If it only 22 hr drive, i will do the drive for sure. Since Sam is very knowledgeable and he done it before. So the chance for him to **** up are probably alot less. Take a trip to banff, it super nice

Hi I have been looking into this for a while have decided to go with calgary autoworks they do malone tunning they recommend stage 1 for daily lifetime tune and can delete egr add blue and do if you wish a custome exhaust. just waiting to get the funds together then will pull the trigger.

A question for you. Have you done an oil change on your Glk250 after the delete? If so did you use a different grade of oil since the Dpf compatible no longer an issue? Thanks again. Your thread made a huge different for my journey with this car.

I still use the same grade of oil from dealership. Still doing it every 15k km. Honestly, after the car got the delete done, it feels like a normal gas car. I think the glk 250 can easily last for 300 000 km with the delete done. I am at 134 000 km now. So far, i am able to change oil myself , clean the k&n filter, clean the maf sensor, change diesel fuel filter, change transmission fluid. How many miles u have on urs? u don't want to put too much miles on it before u do the delete since the carbon will buils up

Btw, what scanner tool did you used to reset your maintenance light after the oil change or does that issue exist? I can't even get my Windshield washer fluids light to shut off with this car. I read somewhere on this forum that you have to use a certain brand of fluids otherwise it will not work. Seem highly excessive for washer fluids.

Ok to bypass the adblue count down, you can try this method
https://youtu.be/yVN8fbLGFjg
This one does not require any tools or obd2 to reset it
For oil change interval or service reset, you can follow this video
https://youtu.be/k4KymF6Z5XU
For your windshield washer fluid low, that one i am suspected faulty sensor, i never have problem with mine(knock on the wood). I will go search around on google and see what other plp say about it

So.. Forgive me if this has been addressed. If I'd follow the foodsteps of the OP, is there anyway this can pass California smog test? I mean, nowadays, smog test consists of a visual inspection and as long as the OBDII port is not throwing any codes, it's considered a pass. Sounds like it's passable. with an updated ECU.
