Problems/Issues after Emissions Recall Performed?

Is the car gushing oil onto your garage floor? If so, consider usual culprits, oil filter pedestal, oil cooler seals, turbo. Assuming that is not the problem, has the failure-prone PCV valve been replaced? When these fail they allow a surprisingly large amount of oil to be sucked into the intake. Replacement can be performed by an intermediate-level amateur with the right tools (including a 1/4" E-torx 10.

DEF Consumption
I had my emissons recall done about 5k miles ago, everything seems fine for the most part. Getting only slightly less MPG than before, but that could be the colder outside temps. I just had the indicator come on for the first time since the service to add DEF, the tank took 5 gallons and is not full. Should MB have filled it?
I am curious how much DEF should go in to fill after indication and how many miles you are getting between filling and the indicator going off again.
Cheers,
Tony

MB sedans do have big DEF tanks, designed to last between oil changes.
Sprinter has smaller tank, who needs frequent refills (about every 6000 miles) Still did not figure it out on my GLE as I don't drive it too much.
Beware of not topping of the DEF tanks, as that will fool the ultrasonic gauge, what might lead to lot of troubles.
I think adding 2.5 gallons from standard container for average owner is the best. This way DEF will not age, you will not carry "dead weight" and you will not fool the gauge.
Low level DEF warning is still giving you at least 2000 miles before empty, so plenty of time to refill.

From my experience at dealers and from reading the recall, CEL diagnostic cost is covered only if recall component caused CEL. If not you pay (which I had to 2 times ). In Northern California, this diagnosis cost >300 and long appointment wait.
It is best to be reasonable, and not **** off local dealer. You will need them at some point.

+1 on Kajtek's observations and suggestions. Sprinters require frequent refills. The passenger vehicles not so much as they have larger DEF tanks but I also only drive mine between 5,000 - 8,000kms between oil changes and thus DEF top-ups.
Whatever you do, refill it and use an ENTIRE jug at once - as in don't try to keep if anything is left over in the DEF jug - as the water in it can evaporate and the ammonia then starts to crystallize, which will bugger things up in the car if you then use the bad DEF fluid for a top-up. Get a jug (or two) and use it (them) at once. There's no need to fill it up to the top.

Didn't know DEF could age! Once I figure out how far the 5 gallons I put in will take me until the indicator comes on I will put in less.
2000 miles from low warning!!! Dang, I thought it was going to start a count-down like other diesels do. Good to know. Now I am curious if it is still 2k miles AFTER the recall!

Whoops...it's an ML350 (W164). I was told it will hold 7.5 gallons (probably a 10 liter tank?) from empty safely... maybe?

Yes, DEF goes bad after a while, so always use fresh fluid and the entire jug at once - throw away any unused fluid. Do not let it get in contact with any aluminum parts.

Running out of windshield fluid will not convert your car into brick.
LOW DEF will lead to countdown and no more start.
I advise buying monitoring scanner for diesels, like ScanGauge.
That sure can take lot of unknown from vehicle ownership.

Thanks to all on answering my DEF consumption questions, now onto the next thing!!
As stated above, I added 5gal DEF for the first time after emissons recall was completed. That was two days ago, and I still have the AdBlu indicator on my dash. I searched around for ways to reset, tried the 30 seconds in position 1 thing with no luck. Found another with gas pedal/key switch shenanigans that did not work. Called the stealership because now I have a 5 year warranty on emissons related stuff.
I am doing a bunch of driving over the next few weeks and dont want to get stranded. Anyone know a way to reset the indicator before I get the countdown?

When the DEF level gets below 3 liters, you'll also get a CEL - which is when the "starts remaining" countdown starts... but if the sender is stuck above that you'll never get the CEL and thus the countdown.
And, the "Add DEF" message or light doesn't go out as soon as you add more DEF... it takes a number of starts for the car's computer and sensors to update (at least that's how it works on the Sprinters). You simply may not have reached that point yet after you filled up. See what happens after you've driven it for a while... no need to panic yet.

I am not sure I understand what y ou mean, but it is fairly clearly spelled out in the settlement as to whether diagnostic procedures are covered. And, no shop will perform free diagnostic testing unless you intend to service the vehicle there. They may simply scan any codes codes for free, but that's where the free diagnostic coverage ends.
The Extended Modification Warranty will cover the cost of any OBD Diagnostic Scan for malfunctions that trigger the MIL, regardless of whether the malfunction is attributable to a part that is covered under the Extended Modification Warranty, as well as the cost of troubleshooting to determine the reason for the malfunction, but only if the malfunction is determined to be attributable to a part that is covered under the Extended Modification Warranty.

P.S. Sorry - I think the misunderstanding may be the "diagnostic scan" part. Yes, they will scan the car for codes free of charge... but just scanning for codes is more often than not insufficient to determine what has actually failed without performing additional diagnostics. That is what I was referring to... not just the scan for codes that anyone can do in 30 seconds with a $15 code scanner.

2009 R320 CDI Bluetec
I need to jump into this post, because I’m experience some issues with my R320 Bluetec that didn’t exist prior to the emissions correction that was done in September. Issues are:
1 Excessive oil consumption (about 2 quarts every 300 miles) and no visible oil leaks.
2 Diesel exhaust smell that enters the cabin
3 P2201 and P2200 NOx Sensor CEL codes
4 Def fluid filled but will not reset remaining starts.
My 2 cents. Just spent $900+ at the stealership for the NOx codes, but they attribute that to, of all things, a “leaking” vaccuum pump. LOL. I’m about to raise hell.

Long story short: my stealership gave me a $7000 laundry list of repairs and the independent mechanic verified they were %100 wrong with their diagnosis and fixed other things for $3200 to solve my complaints.

2014ML 350 Blutec
There seems to be a large variation in how these vehicles perform over the long term. My 2014 ML Bluetec purchased new has been one of the best vehicles I have owned. AEM performed at 102,000 now,at 143,000. No leaks, no oil consumption and a joy to drive. I was hoping I might be one of the ones chosen to monitor per EPA when settlement was finalized but doubt that will happen. Taking it in in several weeks for oil change, fuel filter and air filters.Always been done at dealers across the country. May try power is down, fuel mileage is down and rough idle to,see if anything is going on but really it just purrs like it always has. About every 3,000 miles dump in a 2.5 ad blue tank and throw the rest.Sorry for you folks having problems. Radiator had a leak and oil filter housing had a leak, that’s it. Hard to even consider trading! Not driven on many short trips without making sure it gets warmed up, after normal trips in this hot FL weather I make sure it has had a slow trip,home and pop open the hood to let the hot air out. Seems to be working fine for me. Hoping for another 140,000! Oh, oil changes at Dealer between 7,500 and 8,000 miles

Problems with oil since emissions recall
There is a Facebook group I just joined with other owners having the same problem since the recall. The dealership has been fantastic! It is Mercedes that is refusing to deal with this issue even though they know it is a problem. I can only go about 1000 k without having to add more oil.

14 GL 350, 23Chevy Bolt EV and 22 EUV
My 14 350 GL350 has been a remarkable vehicle . At 102,000 mi, had AEM over 3 years ago with zero problems.i must be one of the lucky ones. All warm weather driving .
I’ll be exchanging it for an EV SUV, either a Volvo EX 90, or the Lucid Gravity, later this year.
It’s been interesting to follow the diesel forum…
