AEM completed on my ML-250, also filed my claim. On another note, I don't understand why the DEF tank and heater aren't covered in this new warranty.
The note for my E class extends warranty on
DEF injector
DEF injector controller
DEF supply module
DEF pump
Temperature sensor unit
also there is note about free OBD diagnosis scan for malfunction that trigger MIL.
Tank is a tank, I don't think I'd worry about its warranty, but isn't DEF pump and DEF heater in the same unit?
We will have to live to see how dealers will play those things.
My friend got 5 letters for vehicles he no longer owns.
PO is entitled to about $900 participation, but
1. I assume the present owner has to complete the modifications
I am a previous owner and have submitted my claim already - claim docs. simply require proof of previous ownership, no requirement for current owner to complete the modification.

The $900 (approx) is split among the number of PO's who file a claim - in your example, if all 4 prior owners submitted a claim, they'd each get $225

The DEF pump sits on top of the heater. If you look at the MB parts catalog, they pump is listed as a separate part, repair kit P/N 002-470-68-94-64. The DEF Heater is shown as a separate part also listed as a repair kit P/N 212-471-05-75. The temperature sensor unit lives in the heater assembly, along with the level sensors. I got my car back on Friday, and the MIL popped back on this morning on my way into work. I'll schedule it in for a stop, but I do not expect if it's the level sensor code again that it will be covered under warranty. It looks like the only part of the heater assembly covered is the temperature sensor. The heater itself and the level sensors look to not be covered. Again, I have no idea why.
The temp sensor is integrated with the level sensor. The temp sensor is a listed part under the campaign. The level sensor is not a listed part. HOWEVER, the Campaign states, " Parts Covered Under Extended Warranty: The Extended Modification Warranty covers the emissions control system, including (1) all components which are replaced as part of the emission modification, and (2) any component which can be reasonably impacted by effects of the emission modification." The temp sensor would be faulty if the level sensor component within it is inoperable. The temp sensor is the level sensor, they are not separate part numbers.
Now, the fact that the DEF heater is not a listed part or a replaced part is a problem, because that is a separate, unlisted part, not replaced as part of the emission modification, an unreliable component, and about a $3,000 dealer repair. The dealer will follow the warranty to the letter and the heater is not covered.
That being said, prior to this settlement if you needed a level sensor, temp sensor, or a DEF heater, the dealer would not replace those individual parts. Instead, the repair called for an entire DEF tank assembly, hence, the $3,000 repair cost. Now, with the settlement wording, you can bet that we will be on the hook for the labor to remove and reinstall the tank and replace the heater alone, same cost, ~$3.000.
DO NOT LET YOUR DEF TANK RUN DRY. DO NOT RELY ON THE LEVEL SENSOR TO LET YOU KNOW YOU NEED A REFILL. KEEP THE DEF TANK TOPPED OFF. THE HEATERS FAIL BECAUSE TANKS ARE RUN DRY. TOP UP AT EVERY REFILL BECAUSE THE AEM CALLS FOR MORE DEF.

The DEF tank issue is big story on Sprinters, where whole tank is welded plastic unit and no parts can be replaced separately. Not only Sprinters tank cost over $3000, but when we have about 7.000 Bluetec E class in USA, we do have well over 100,000 affected Sprinters.
The often DEF refill advise is very common on Sprinter forum. Lot of members use ScanGauge to monitor DEF level and refill at about 50%. Unfortunately the OM642 ECU is not supporting DEF gauge, so that brings more troubles.
Newer Sprinters have DEF gauge on dashboard, so somebody in Stuttgart sober up.
In Appendix A I found what I'd been looking for for a while - the terms of the extended warranty.
I have a 2014 GL350 with 180k miles on it. It just clogged up and wont make boost and it has a timing chain tensioner that is slow to pump up when starting. After about 3-5 seconds it’s fine. So will this settlement take care of these issues?
I purchased the SUV new and have loved every mile in it. Love the fuel mileage it delivers. Such a comfortable long hauler.
As I understand the process, you have to have the AEM done first, then the additional warranty kicks in. The appendix tells you what they will do to your specific car and when, then the the items you now have problems with could be covered. I get my 2014 ML 350 back Tuesday morning. I wanted mine done right away so I have all the additional items covered. 102,000 and been perfect so far but I am sure things are coming and I couldn’t be happier to have basically top end of engine covered. Will report on diveabilty with new updates once I get a few miles on her. By the way I have loaner since Thursday at no charge, but always have gotten one.
Try to understand the difference between modifications and following warranty.
The warranty won't exist when you don't do the modifications.
Let me refresh the link what modifications apply https://www.epa.gov/enforcement/daim...vil-settlement
There also is a note that the warranty will cover the parts who might be affected by modifications, so legally MB USA has the right to refuse taking care of preexisting conditions.
It is a case for lawyers to finalize I guess.
Got my car back, MBUSA paid for the O2 sensor as part of the revision after some effort on my part.
No mileage change on mine, but it stays lower rpm/ shifts sooner when cold and it is HARD TO START. Cranks in the morning 5-6 seconds instead of 1-2 after glow plug time.
I’ve taken my ML250 on a couple of extended drives since the modification. First 60 miles at 50 mph avg. I got 42.5 mpg, never before has that happened. Today drove 100 miles at 70 mph avg., I got 33.6 which is about normal. So far I’m happy. 😁

I have 4 Bluetecs in my stable and all of them fire up on the 1st turn.
My 2014 E250 BT sedan was park for 20 months and with good batteries and fresh DEF fired on 1st turn as well.
I am in warm climate thought.
Picked up my V6 Sprinter after modifications. Can't notice any performance difference, but took it for smog check on my way back and it measured 0 emissions.
They have new probe in NV for 10 days. No longer probe goes inside the pipe, but headphone-type probes measure the mixture outside the tip.
Sprinters newer were sport vehicles, but if I would have to guess, I'd say the acceleration is better.
Will know more in about 3 days when my 2l diesel sedan will have modification done.
The 4-banger in sedan was displaying traction light when floored on 2nd gear on dry asphalt, so any noticeable difference will either do a burnout, or not light the traction.
Very happy about this settlement. Both my bluetecs have been flawlessly trouble free. With no new diesels coming out, this gives me years more with the current ones without having to switch to a Dodge/Cummins 2500.
The settlement should bring some level to the market.
Lately MB sedans from 1980's are selling for more than those 2008-2012 models.
I am not talking about classic cars, but daily drivers.
I think OM651 engine is real marvel and sounds like Stuttgart will hold on sending us its younger, OM654 brother.
So the 60 mpg luxury sedans will not have much competition.
I mean I am saving for 2.5 seconds Lucid, but nobody wants to give me 2nd mortgage at 60% of house value level.
Had the modification done on my 2015 GL350, ~77k miles. Seems to run fine but haven't tried towing my boat. Check Engine MIL came on within a day. Made an appointment, no loaners for this type of work, cited a global shortage of cars, and told me that diagnosis of the MIL would be $175.00 if not related to AEM. When I cited the Extended Warranty that said OBD Diagnosis Scan was covered, I was told to call the number on the related website and asked if I wanted to cancel the appoinment for tomorrow. Nope, I'll keep it. Double checked the Warranty coverage the scan is covered but further diagnosis not related to a warranted item is not. My Foxwell reader indicated Fuel Injector errors for cylinders 1,2 and 5. Fuel Injectors seem to be covered for 6 mos. or 6k miles. Anyone have issues related to the AEM. Any advice in working through this with the dealer or anything that might be of help as I work through this issue?

Nope. Fuel injectors are specifically covered by the extended AEM warranty for the full duration. (source attached)
Since this occurred right after the AEM was completed you are either very lucky to be covered by the AEM extended warranty or, more likely, they did not complete the AEM properly.
IMHO, it seems odd that multiple injectors would all start throwing codes at once.

Yep, I see that now - full duration of warranty for EMC4. Odd indeed that this occurred right after the mod. The shop is super busy right now and the car just sat for a day before work was able to be started. The SA commented that it was a complicated modification - not a confidence statement that things were done correctly. I'll post what resolves or not.
Which dealer is this? They should honor the settlement as the dealers are legally bound. We should avoid this service department!
So far during this AEM experience they have made me feel like a 2nd class customer, likely because I do most of my own maintenance, and will likely now take any non-covered repairs to an indy. Mercedes Benz of Arrowhead, bought the GL there and warranty work there. Depending on the rest of this experience, may change to one of the other 4 MB dealer service departments in the Phoenix area if I need dealer work/parts.
Wrong dealer. I just had my AEM done at MB Naples and couldn’t be happier. I have never spent a dime at an MB dealer for service and got quality service.
Just had my 2014 ML returned today after the AEM was completed. Haven’t driven it much but initial impression is positive. Shifts great, seems to have more power but no way to really know except my feeling. Positive experience with MB of Gainesville, Fl. Have always been provided a loaner. More updates In a couple weeks but feel much better with warranty on basically top half of engine!
