MB BlueTEC Settlement Site is UP






As long as the new heater is working and there are no faults stored in the ECU (and you're on the stock programming), I think you'd be fine.
It's not like you removed the heater, disabled the system, removed it from the DEF tank, etc. etc. You fixed a very common failure item (mine is currently dead, need to book a trip to get it repaired under the AEM warranty).




I can see that most of the exhaust has been replaced. Starting from the behind turbo exhaust outlet and all the way to mufflers has been replaced. So new DPF, NOx sensors, Cat converter. EGT sensor (I think?), one right after turbo has been plugged up, not sure where it was relocated. I've been told about an hour software upgrade has been performed as well.
New DPF
You can see the bolt plug just peeking out behind the airbox a little.

Some received a TCU update or other transmission service. Some got various components of the AdBlue system replaced. Some required EGR valve and/or cooler peripherals.
I guess it all depends on the dealership, the individual car and its current state before the AEM work.

For those that haven't yet received their funds, I've been told they're mailed out in batches. Mine must be from this latest batch.
is that written in the settlement? I will keep reading myself, and if I find something about this I will share








Transmission adaptive learn reset procedure:
1. Turn the key to position II (run). Do not start the engine.
2. Press the throttle to the floor. Activate the kickdown switch.
3. Keep the gas pedal pressed for at least 10 seconds.
4. Turn key to OFF, position 0. Don’t remove the key.
5. Release the gas pedal.
6. Wait 2 minutes. During this process, key is left in the ignition in the OFF position.
7. Start the car and drive for 15 minutes.
So. As Billy Bob Shakespeare may ask “to modify or not to modify…that is the question. Thanks gents.
DEF needs to be replenished since it is a consumable item. The AdBlue heater being failed may affect regens when it's close to freezing or below, and you will get a CEL (check engine light).
I would suggest getting it done, collecting the monies and having the peace of mind of an extended warranty for the next 4yrs/48k miles that covers a whole lot.


1- The high pressure lines on my DEF system were "clogged" and not covered by the field measure warranty. I was charged 1700 dollars for that. It resolved a nagging CEL. I just don't understand how the DEF system is covered but not the hoses attached to it.
2- After a month the transmission not smoothing out. I took it back so it would get reset. Seems better now. ****ting from D2 to D1 seems a bit rough still
3- passenger side blind spot sensor is acting super funny. It would go red on higher than normal curbs and open spaces. I didn't think it was related but it was peculiar that it started to happen after the field measure. The dealership replaced all 4 sensors. It didn't go away. Now I'm thinking maybe the new program they put in my car was no good.
Called the dealer and they said it was part of the programming. and the parts change.
The shifting has gotten better, probably adaptive, and from research here etc it seems the display of individual gear it is in is common to newer MB.
Wondering why they changed the trans valve body.. still wondering but it is probably a more computer controlled version
The repair procedure for the AEM showed if you had a 14 or 15 there is no trans work
If you have a 2013 it gets the transmission parts: Valve body, different filter possibly and a new fill pipe different than want comes in the service kit it said. and 10 quarts of oil.
Like others have said, sucks to have just changed trans oil 25K ago, and what insidious reason do they have for changing the trans parts.
This is the 2013 procedure https://mb.oemdtc.com/1212/bluetec-u...es-benz-glk250

My only issue is I trust my specialist mechanic more than the dealers' to mess with the trans fluid, but I agree free oil and I was getting a P2002 code and probably needed a DPF anyway.
I should have held off on my EGT pre turbo sensor, they are sort of mentioned in some literature but I was afraid bringing it in with the code and paying 500 for a 200 fix.
Hoping fuel economy and DEF consumption reasonable. Never got over 35 highway before AEM


After others received theirs earlier this year I heard nothing. In April I received a Release to sign. Immediately signed and returned it. Tail end of June I had received nothing, no money, not "go to hell," nothing. I wrote and received generic letter that claims were being processed. I objected since requesting Release indicates approval and check should be issued. They responded "in due course" that the claim was being processed. A month later I received the check. Either those lawyers and the administration of this matter are incompetent, all screwed up, or they purposely delayed payment in order to hold on to the funds for the interest they accrue, until the last possible minute.
Through all this I received another recall for that intercooler hose to be changed. Took it in again, 220 miles away, and they did a whole bunch of work in connection with that. Lots of parts changed. I've seen no effect on driveability, fuel mileage, or anything else. Difference only is that in the transmission display I see a few gears without the "D" in the display, usually when downshifting using the paddles. Little difference in fuel mileage. Better if anything. Freeway and no traffic, speeds "a bit over the speed limit", and I'm getting right at 40 mpg! I'm quite happy!
