Recently my 2015 GL350 started making some rattling noise for a couple seconds on cold start. The dealer 'warranty department' told me that it would take 2 hrs to diagnose and if it was the timing belt it would be under the AEM warranty - including diagnoses - but if it was the 'chain tensioner' then it would not be covered. Interesting and a little strange that the timing belt is covered but associated components are not. Also - if it is the chain - then wouldn't they have to replace the tensioner at the same time as the chain? I haven't asked them if this was based on info from MBUSA.

Pmount1!

Disposed of envelope but it was very similar to this.

I think it's your typical stealership response where their brains are genetically modified to extract as much dollars as possible so long as they don't get caught. I'd check with another dealer.

Your response above only indicates that it is your brain that is genetically modified to expect everyone else to be as dishonest as you are. Have you looked at the AEM description, the parts that are warrantied and the specific language regarding various diagnostics and who is responsible for the cost of the same depending on the outcome?

Check arrived ($3590) and cashed. Thanks MB.

So your reading of this is that the components covered under 'Cylinder Head Assembly' are just those listed in the parentheses and 'Engine Timing Chain' would not include tensioner? I can see that. I guess what I am asking is what are others experience with AEM warranty repairs - but probably too soon to really get much feedback.

No Sir - if the tensioner itself was covered, it would have been explicitly mentioned like the rest of the components.

The double-row timing chains are known to stretch despite the fact that they are considered lifetime items (especially on the MLs and GLs), so you may be in luck. You could also have a late-date engine with the updated single row chain, which is actually more durable and less prone to stretching than the double row - but there is no way to know until you check.

Mercedes has a special tool (gauge) that screws in a port on the passenger side of the engine, presses against the chain and shows how much the chain has stretched without having to tear down the engine, lock the camshafts and measure the stretch on the crank hub, but it easily takes 1.5 - 2 hours just to be able to get to the side port. I am afraid that the dealership telling you that it takes 2 hours to do the check and that it may or may not be the chain (which also determines who pays for the diagnostic, not just the repair) is pretty much spot-on.

Looks like EMC 5 was approved by EPA.

Great!! going to try to call and get an appointment right away!

xsramo

I called my dealer in NE and they have not received notification yet. I pointed them to the documets on on site - they took my Vin and # and said they would call as soon as they recieve the notice.

Direct from MBusa rep:

The national database updates 1-day post-approval: so if it's 13th then 14 the dealer's comps will get it.

So if it goes like the S class did it will hit then 1 day after
so Jan 14th would be the day

Vehicle (VIN) Eligible for Emissions Modification?
Yes
Emissions Modification Approved by EPA and CARB?
Yes, Expected Launch 01/13/2022

Call and get you name on the books for friday

I filed 2 claims the beginning of April 2021. I have the claim numbers and a sheet that says "Your claim has been submitted successfully". Is there somewhere to check the status of the claim or do we just wait? Thanks in advance for a reply.

kajtek1

I did 3 AEMs in about 10 days period back in March 2020.
The check for the 1st arrived 2 weeks ago, while I am still waiting for other 2 checks.
There is nothing worse than waiting for free money?

mfab

I got the checks for both of my cars. Slightly different amounts.

The day has come EMC5 Go get your AEMS!
Finally!

Scheduled for emc5 on Thursday at my local dealer. I'm thinking about asking them to replace oil cooler seals while they're in there...anyone else trying this?

kajtek1

Did you check the price on oil cooler job?

xsramo

I asked for a quote today, waiting for a call back. I think intakes come off with emc5 and thought it could be cheap insurance.

xsramo

Well talked to the dealer today and got a mixed answer. They are not sure if the intakes do come off for EMC 5 and are looking into it. They said they would be willing to do the oil coolers if the intakes do come off though. Here's what EMC 5 lists as the parts list.

• Software Update
• New NOx sensors (TT3)
• New ECU
• New copper catalyst, DOC, DPF
• New DEF Injector
• New Crankcase Ventilation Valve (including line and heating element)
• New Left and Right Charge Air Distribution Line/Intake Manifold (incl. Intake Port Shutoff Linkage)
• New Charge Air Distribution Line Transverse Tube
• New Intake Port Shut-Off Actuator
• New Clean Air Duct with Mass Air Flow Sensors
• New EGR Valve (Actuator), EGR Cooler, and EGR Line(s)
• Lambda sensor

I wish they would include the mercedes part numbers so we'd know what each of these things actually are. I thought the one I bolded may include the intake manifold. Anyone have any idea if the intake manifold is replaced under EMC 5? I looked on mbepc and the "charge air distrubution line" looks like the intake manifold, part number: A 642 090 78 37.

Just got an email from the law firm today telling me I'll receive my money next month. No sum was mentioned..

gkgeiger

May I ask when you filed your claim, and did everyone who received a payment get a letter from the law firm before the check arrived?

DESAL

I got an email from the claim administrator on the 14th. restating the parameters of the suit. But nothing from the lawyers. So, I called the administrator. They found my claim but could not give me a date for mailing of a check. The lady did say that the claims are processed in the order that they are received. A check would be mailed as long as all the info is correct, and the claim is approved. So, it's a first come first serve as long as you pass. I filed 5/3/21 and I no longer own the MB.

Does anyone know if the AEM fixes the Oil Consumption Issue in the 2011 ML350's. Also has the modification been a good thing for your vehicle as far as how the car runs?

Thank you,

kajtek1

the warranty is post-AEM, so legally the dealer can charge you for fixing all known malfunctions before performing AEM.
However if high oil consumption would go unnoticed during AEM, you might follow the new warranty with it.
Think about it very carefully.

Marty, you're aware that DEF is easily purchased at any auto parts store, home improvement center, even WalMart, for about $5-6/gal? All you need to do to change it is pull up the trunk liner and unscrew the tank cap. The DEF packaging usually comes with a plastic extendable hose, obviating the need even for a funnel (although it never hurts to use one). Seriously, this is a 1 out of 10 on the difficulty scale of maintenance items. Don't take it to the dealer for this service. They are going to upcharge you 3x for the MB branded AdBlue DEF, which is IDENTICAL in every way to the generic DEF sold at stores (and at the store you can check the manufacture date of the DEF, which the dealer will NOT tell you). Finally, you'll have diagnostic and labor fees to pay as well.

IF you suspect a leak, buy some DEF, fill up the tank (about 5-8 gals if empty--see your car manual capacity pages). Then monitor your parking spot/garage floor for any leaks or white residue under the car. You can also assess DEF tank levels with some scanners (Autel AP200 sold at WalMart as HyperTough HT200 is my fave at $49 bucks) or just top off the tank in a few weeks/months to assess how much it took and thereby calculate your consumption, which should be around 625 miles/liter or about 2500 miles/gallon. Do the math and if it's higher than that, you may have a leak. Peasy. You got this!
