I have a dire need to terminate the EGR, DPF, and SCR systems in my 2014 MB E250 (OM651).
I'm hopeful that the kit designed for the GLK 250 mentioned in the GLK 250 thread here will be compatible with my E-Class sedan. See pdf showing current problem and exhaust pictures.
I investigated this last year due to some temporary problems with the DEF system that strangely disappeared with time and following stricter DEF top-off routines. At that time I did not see a good fit solution for my vehicle
Today, my luck is not so good. The crude diagnostics I have available indicate the DPF is clogged and likely one (or more) exhaust sensor malfunctions. The vehicle is currently in limp home mode.
Do you have any advice on preparations for the modification and the maintenance routines that one should follow after the modification?
I live near Charlotte, NC. I am reaching out to several providers within 150-miles to quote the service. It seems like (RawTek/Malone) or (Buzzken/JR) are my options.
I appreciate any information you all have shared on your experience having completing the modification.
Most likely your DPF is not plugged; a sensor (or more) thinks that and puts your truck in "limp mode" to protect itself.
I can vouch for OETuning as a good, permanent solution. I'm not affiliated with them in any way. They may provide discounts for MBworld forum members. Currently running their software and couldn't be happier, nothing needs to be chopped off the car either. You just flash the tune in your garage/driveway and you're set. Here's the site and info: https://www.oetuning.com/products/me...glk250-bluetec and I would call or email them to ask about discount before purchasing.
You can order an end-user device for reading/writing files using any android smartphone/tablet (no iPhone for now). it supports MB ecus (EDC17+ and MED17.7+). No need to go to tuner shops. Everything online. http://ecuprogram.com/droid-personal-flasher Andorid MB flasher

Good luck.
Thank you for the responses. However, I am skeptical software tune-only solutions. I envision catastrophic failure and fire risk if the DPF is not removed. The engine would have no knowledge of a clogged DPF, correct? I started a thread in the correct category for my sedan here:
Just want to give you guys an update regarding on the delete that I completed.
No issues with the delete so far except rough idle during the cold start. I believe that something to do with my injectors are getting clogged. I am currently having a leak in my brake system. I am gonna get Sam to check it out and get the leak repair. Other than that GLK still running strong

keep me posted. my rough idle started immediately after tune and I cant figure it out. I tried to p.m u but cant.
Not after the delete, but when my injector are clogged, i have similar issues in cold start. Once the vehicle warm up, the rough idle will go away
I had my GLK 250 ECU DPF remapped by a Benz tuner in Toronto and the next day it had a rough start with the cold engine, and now it takes a couple cranks every morning to get going. I'm wondering if it the injectors or fuel filter ....any thoughts?
I ordered a new filter which I will put in this week and now am considering repiping the DPF altogether or boring out the filter itself.

Well I made the jump. Got the Stage 1 tune with full delete. Waiting for the hardware to be removed now. Looking forward to my GLK with no NOx, DPF, AdBlue issues for many years to come.
Rawtekinc.com pipe, was under $700 American but almost $1100 Canadian by the time shipping was added. The obd2 full delete was over $1000, I see they have just one available. To apply the obd2 delete was simple, just follow the instructions on your stereo. I had the shop change the exhaust, the old exhaust was given back, with the sensors, and i can probably recoup $500. Here's the link for the delete https://www.ebay.ca/i/233188825627?u...rover%252F2%25
How much did the shop charge you to switch out the exhaust?
Hi,
Can you please share where did you get Stage 1 tune with full delete done?
Thanks

I'm sticking with the software tune only, no real reason to chop off parts. In case I ever want/need to revert back to stock, it's just a 5 minute ECU read/write.
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.

I was told by many people who work on these cars and do deletes etc not to go that route. The DPF builds back pressure and over time destroys your engine. Good idea emptying the tank. Will do that too. I just filled it a month ago!

I got it done by a private tuner in Vancouver that specializes in Mercedes. But there are shops in Calgary and Richmond that do it for you as well. Also OEtuning from Cali.

I don’t think that’s true, since regens occur even with the tune. Back pressure would build only if the DPF can’t complete its regens.
Monitoring the DPF pressure differential for the past year reveals a 0.1 PSI difference. That is to say, none.
Thank you
I am in Ontario so if you or anyone have any information that would be helpful.

Keep in mind that there are tuners and tuners out there. I've read many horror stories about tuners who don't know what they're doing. Many don't spend the time to understand what the fuel/boost/injection/timing/et al settings really do and how they interact at various RPM and engine load. A lot of them just take shortcuts and basically bump up all the settings across the board to make more power without understanding potential consequences.
To make matters worse, some tuners disable important safety items to prevent any error codes from popping up ever again. I heard recently from an expert in the field that he found a tune with more than 1400 individual trouble codes disabled in a vehicle. It ran like crap but never lit up the CEL, and the poor owner had no idea what was going on or where to start fixing since the ECU wasn't spitting out any codes.
Just making the point that quality is important, and not all tuners are on the up and up. YMMV...
Very good point. That's why i appreciate if someone can recommend tuner in Ontario.
Thank you.
