No idea about the california smok test, but there are no codes after the ecu update. The thing is, you can smell the diesel after completed the delete, but no black smoke for me so far.

Did you do the removal of the DPF and everything underneath yourself, or did the place you took it do everything? Was this the delete pipe you used?

https://www.tunemyeuro.com/mercedes-...-2017-buzzken/

I'm keenly keeping an eye on this thread, my gf just bought a 2015 end of December and it's been to the dealership twice already with DEF issues. Froze up twice now. Once when we were on our way to the dealership for unrelated warranty work. Then again coming home that same day. AdBlue count down came on, but wouldn't reset itself (not sure if it should) once I got it inside at my work for a day and a half. We're both getting frustrated with the DEF freezing, and with the temps in store for us (-25 or so daytime highs) I don't see it suddenly working smooth. I'm in Manitoba, so Calgary is an easy trip, could visit some friends and get two birds stoned at once.

Seems like a great vehicle other than the DEF/DPF/SCR system. Seems way more finicky than that of the North American manufacturers in the HD pickups.

I am not sure if that the same kit i used on my glk. You have to give Sam a call. The price i paid included installation and tuning. Depending on how you want to tune ur vehicle, u may have to stay a few days

No problem.

When you say it has a diesel smell after, how bad are we talking?

Hmm you will notice the smell when you first start the vehicle, special in winter time. after that, you wont smell any diesel.

Perhaps your DEF tank heater is on its last leg? You are in Manitoba so winter cold snaps could be even worse than in Calgary. My 2015 GLK2 was parked outside at -25C last winter and started right up in the morning without any warnings... but then my charge air temp sensor froze, throwing the truck into a limp mode. Took a while to thaw it in the mall's underground parking

There is an aftermarket replacement here: https://xemodex.ca/ca/product/def-ta...s-benz-glk250/ . I haven't tried it though, OEM still works "knock on wood".

It was weak, but the dealer replaced it on the 18th the first time it froze up on us.

Just went to the dealership today to pick up the GLK, really wasn't impressed with the answers they gave me. They're very helpful and at least seemed genuinely concerned and interested in helping make things right, but the emissions system sounds absolutely terrible on these vehicles. Basically every time it freezes up, if it gets to the point where the start counter comes on, it MUST go back to the dealership to be reset. The vehicle can't tell the system is thawed out, the tank heater does not have enough power to thaw the tank, and it only runs when the car is running. When I mentioned a delete they their answer was basically "we'll pretend we didn't hear that" and were super non committal when it came to answering how a delete would impact any future warranty claims.

Did you hear what happened to VW? Dieselgate? They ( any German car manufacturer of consumer diesels) are all super touchy-feely now 😂 Thatís probably why such reaction to your question.

The emissions system is just too complex and fragile for our -25C and below winter temps. They need to beef it up for Canada-spec cars. Not just slap block heater on it.

I wonder if there is a way to reset counter via iCarSoft MB tool? There is also engineering menu - I think you can get to it via pressing and holding 1+ #+ hang up buttons at the center console. Donít know if they have anything there, related to start counter reset.

Hello all, great post, I wish I would have seen it before when my car first started asking for oil out of no where, and just like quron_southwest mentioned at the beginning of this thread, it started with 1 qt every 1000 miles down to a qt every 200 miles.
At this point and after reading all this, I will definitely opt for the DPF removal and ECU mod, but I'm going to have the existing DPF re-installed after opening it removing the guts, that way I will keep the same look as OEM, what do you think?
The muffler has the DPF and the Catalytic converter, the bypass pipe quron_southwest got is for both or just the DPF?
I will be having the muffler and ECU removed tomorrow and shipped same day if possible, any input will greatly appreciated, thank you.

I am in California. I was wondering about this too.

I figure all you have to do is gutting out the DPF and put it back so it looks all the same. The rest is just the ECU tuning or the emulator board.

Could someone confirm this ?

Not Just the dpf, u have also remove the SCR. There is a dpf kit u can get. I got mine from ecutune for approximately $850, can't really remember the price.

Thanks for the pointer. I can't go to the website ecutune.com for some reasons.
Anyway, I keep seeing a pipe for deleting DPF that cost a lot of money. If I plan to just gut out the DPF and put back the empty shell, I don't need to buy that pipe, correct ?

Hi, sorry i reviewed my initial post and realized the shop call Ecuprogram, if u search Ecuprogram Calgary @ google.ca, u should be able to locate the website and contact the shop.

To be honest, if u think $800 for the parts is expansive, u should switch to gas model. U have to remove the SCR, which is part of the bluetec system. If u have one Nox sensor fail and needs to replace at the dealership, which is about $800.

I do not mind paying $800. But I am still learning, and I have read something like $1000-$2000 for ECU or emulator board and another $1000-$2000 for a straight pipe. That's why I asked if I could just gut the DPF and mount the empty shell without paying for the straight pipe.
So what you are saying is $800 is the total kit for ECU tuning/Emulator as well as a pipe ? Please clarify. Thanks.

The kit is around is around 800, and u r correct, the tune is 1100 and approximately 5hrs of labor for install the kit. Please note, our diesel cannot be tine by OBD2, that why is more expensive. I think this is probably the best 2.5k i ever spent since my glk250 now has almost 160 000km with zero emissions issues after the delete is completed.

Sorry, I still haven't grasp the picture. Ok I understand the tuning part where you have to fix the ECU to.bypass DPF SCR DEF checking. Did you use an emulator board for it or just reprogramming ?

What are included in this DPF delete kit ? Is it just a pipe and mounting ? Can I just have the ECU tune and just gut out the existing DPF?

I think the replacement part for the dpf, new pipe to replace the scr and few more pipes . I am not sure if u can use the existing dpf.

In terms of programming the ecu, u have to contact [email protected] ECU program for more information. If you look back at the pictures that I posted, Sam used few wires to tap into the ECU and flashed with a software. I flashed ROMs in my cell phone and tablet before, but flashing the ecu seems a lot more scary and expensive to fix if something goes south. I can't imagine the replacement cost if u accidentally brick the ECU.

Does anyone know a way to increase the gas mileage of an R320 ? Could tuning do this ?

I am thinking of buying a used R320 CDI or Bluetec, then do a DPF delete, or just go with the boring Toyota Highlander hybrid

Tuning can help with better mileage. I was able to get my best mileage from 5.3l per 100km to 4.8l to 100km

These are awesome results! I had similar results (fuel mileage became much better) with Malone tuning stage 2... except it was on much lighter, FWD Golf TDI :P
