I'll cross my fingers for you. I guess it was just our time to get a bad one. We've purchased many a vehicle, both for personal and our company use, and so far have been very lucky. This entire situation is a first for us.

2011 QX56 (formerly '11 GL350)
Here's a question for you guys:
When they changed the defective NOX sensor down at the other dealership, afterwards started the weird thudding sound in the back whenever I tapped the breaks or came to a stop. At first, they were thinking it was the adblue 'sloshing' around, which I was pretty adament it was NOT, as it wasn't making that THUD when I brought it down to the dealer to have the NOX sensor changed--yet it miraculously started making the THUD the minute I pulled out of the driveway--with the SAME amount of adblue, I'm assuming as when I pulled it in the day before unless it evaporated overnight..lol...
I casually asked, when they first thought it was because the adblue was going down, that it was making that thud..that if that is the case, I guess you just need to keep topping it off (which I know is ridiculous, but I was still going along with them thinking that thud was the liquid thudding around at each stop--which is just pure ridiculousness) with adblue so you don't get that thudding. He said, yes..that would probably help. So then I explained how silly that seems, that a car, with only 3000 miles on it would need to be continually topped off with adblue so it doesn't thunk--which he agreed-- so I said, but if that is the case, I guess I should just get the adblue myself, from the VW dealer (I've read on this board about it being the same stuff and much cheaper) and he acted confused. Then he called me later and said over and over how I CANNOT ADD ADBLUE (or whatever it is) to my car...IT HAS TO BE MERCEDES BRAND ADBLUE or it will VOID MY ENTIRE WARRANTY on my car..and he said this is VERY IMPORTANT.
Is this true? Honestly, the thudding sound is NOT from my ADBLUE stuff being low, I know it's not--it just started out of the blue after the NOX sensor was replaced-- but is he really serious about it voiding my warranty if I decide to add my own adblue? How can that be?
Just curious what everyones thoughts are on that. I should probably search for my answer, but since this is my own thread, I thought I'd ask here as well.

As for the thudding, to be honest, it does not sound like a liquid thing. More like an exhaust hanger or something.

I bought bottles of adblue from MB Encino and the box said that the Adblue could be used for Volkswagen, Audi, and Mercedes. Go to another dealer...its the same thing. The dealer told me the same thing (that I can only use Mercedes AdBlue) but the AdBlue company is third party and not owned by Mercedes at all. The AdBlue is the same exhaust treatment by other car brands. By the way, I am also receiving a lot of wind noise in my 2010 GL350, but thought it was normal. I also was experiencing weird revs and loud engine noises and I have been averaging 15 mpg. I told MB encino and Keyes Mercedes and they didn't change anything. What dealer did you take it to? Thanks

BS. I buy VW adblue or DEF (diesel exhaust fluid) and take it to my MB dealer and they put it in my tank for me when I had my 20k service flush. As long as the ISO is the same, it doesn't matter. Your GL can't tell what brand of DEF you put in the vehicle. Also MB doesn't make adblue, so that dealer's comment is a little laughable.

I am taking my GL to Mercedes of Oxnard. Not sure how far away that is from wherever you are. The SA I'm dealing with is named Angel and he's a really nice guy. Aside from the Adblue comment, I have been EXTREMELY happy with the way they are treating us. I also have the MB C300 loaner and have had it for over a week. Much better than Keyes, in my opinion. I am unfamiliar with MB of Encino, though.
My gas mileage around town always hovers about 18-20...Most of my driving is never on open freeways. I spend a LOT of time carting 3 kids and all their friends to a zillion practices every day. I was wondering if my turbo problem would have an effect on my gas mileage. I just haven't taken it out on long open road trips to really figure it out.
Good luck finding a dealer who might be able to help you!

I appreciate everyone's comments on the adblue--from my research on this very forum, I was pretty sure he wasn't correct, but I like having all of you as my go-to guys for answers!

2011 QX56 (formerly '11 GL350)
I'm a bit frustrated today...They called and car is still not done. I asked about the knocking sound coming from the back everytime I tap my brakes today and he said he 'thought' they had determined it was just adblue "sloshing" around. I reiterated again that it just couldn't be that, as surely after only 6 weeks of ownership the adblue wouldnt be so low it was sloshing around and causing that large of a thunk. It literally sounds as if I hit something. When I'm in reverse and backing out of a parking spot slowly, and slightly tapping my breaks, I hear the sound and it makes me think I've hit something-- SURELY this can't be acceptable...Grrrr.... I told him that if that is their stance, then I would like them to "top off" the blue tec and if what they are saying is true, the sound should disappear. He agreed. So...we'll see if I still have the clunk with a completely full tank of adblue. The clunk was not there until the NOX sensor was replaced.
He said more parts came in today..and they were going to start putting my car back together but that there was a "LOT of work to be done." I finally asked, a bit confused about all these other parts they had to order and he sort of hem hawed a bit, said something about once they got in there, they found that they needed more "nuts and bolts" and things. What the heck does that mean? So...My question is, will they be hoenst and tell me EXACTLY what they did all this time they've had my car? That is just something I'm curious about. Maybe I should have my husband call and ask questions, because again, I might not understand what they are doing so he doesn't feel the need to explain it-- any-who...
He said he will call me on Monday to "touch base." Anytime he says he will call to 'touch base', it always means it will not be done. So..still no car over this next weekend either. Such a pain...and today I'm a bit frustrated about the whole thing. GRRRRRR. (sigh)
As for the clunking, does anyone else have a weird clunk (they are calling it a harsh slosh) each time they stop at a stop sign or parking space, or tap the brakes? Do any of you hear your adblue making ANY type of noise in your vehicle EVERY time you stop? I think I know the answer, but just thought I'd throw it out there......
Honestly...as this goes on longer and longer, the "wind noise" I was originally complaining about seems to be the least of my worries now....

CALL MB corporate in new jersey - it's still before 5pm, and get this done. They will assign case # and call the dealer for you to put some leverage on them. unfortunately, customers have no leverage.

Yes, the adblue does slosh but you are correct, it is not very noticeable when the tank is full. It is pretty hard to hear until you have a few thousand miles on your GL. It was annoying when I first started hearing it but I got used to it. I also think that as you get used to the brakes you learn to be a little smoother and it doesn't slosh quite as bad.

Back to the stopping by, I told my husband about the nuts and bolts thing and so he wanted to stop by and just talk to them face to face. Turns out, now I understand why the SA was being a bit coy about it all, I don't think he wanted to 1) worry me and 2) get his mechanic in trouble. Apparently, when the mechanic was taking off the turbo, he broke one of the bolts. They had to come from back east. The mechanic came out as soon as we got there and said he owed us an apology and explained what happened. Not a big deal, but he felt bad. I was just a bit confused as to why it was taking so long..and the nuts and bolts story was a bit odd. Now I know. Now we are waiting for the bolt to come in from back east I guess.
I must say, as frustrated as I am. When I am actually talking to these guys (the SA and the mechanic) I walk away not as disappointed as when I went in. In the end,I can't say enough about how nice these guys are. I honestly feel like they are really trying to work all this out for me. I can't ask for much more than that, I guess. (except for maybe a $70k car that works as it's supposed to
So..I'm back to being unfrustrated..for the time being.

Not too unusual for the tech to break something when he is working on the car. AND is it sometimes difficult to get the SA / mechanic to 'fess up'! If the part that breaks is a special bolt - and it is not too hard to imagine a special alloy bolt on the hot side of the turbo - then it will take time to get a replacement in. It is also possible that Mercedes is reluctant to pay for next day air service to get the new part(s) to your dealer. Shame on them in this situation if that is the case.

I was too busy being impressed as he told me how he had another mechanic drive him around in my car, while he laid in the BACK of the car with his head down to the floor listening for the thud. He said it is quite loud and he really honestly things its the Adblue. He had his hand over the adblue tank and "feels" the thunk (hard slosh) with the brakes, etc. I've no reason to not believe him, he was laying across the back of my car trying to figure it out.
I'll just be glad to get it back. I want to start enjoying this car!

My uneducated read is that your car can't be out of service more than 30 days during the first 18 months or 18000 miles whichever occurs first. I hope they get it fixed for you though.

Two quick things; when my turbo died (mine lasted to 80,000 miles) the mechanic broke some bolt trying to remove it and that had to be removed from its seating and replaced, so that's not unheard of. Next, I would suggest, for your own peace of mind, asking the person who has told you that you must use Mercedes' AdBlue or void your warranty to show you where that is specifically documented (and not some "must use approved fluids yadda-yadda" crap because as long as it meets the standards it is an approved fluid). If they cannot show that they are getting some fluid either manufactured only by Mercedes and nobody else or produced specifically only for Mercedes, then they are yanking your chain. Not that it's really such a huge deal but I do really hate it when someone throws around the "will void your warranty" baloney just so they can sell you something that is marked up 10,000% with premium-priced hourly mechanic rates on top of it.

And what a bummer you also lost your turbo. Sheesh...I guess you got 80,000 miles out of yours, but still. I think mine started making the weird whining noise around 2000 miles.

I highly doubt Tamz's noise is the adblue, if it was we would have everybody on these forums complaining about seriously loud thumps from their GL's.

It doesn't make a thumping sound. The adblue tank is about 6 or 7 times the size of a windshield washer fluid reservoir. The carpeted access panel for the spare or in the bluetec's case the tool and adblue compartment, is the only real sound insulation. The only time I can hear sloshing is when I'm parking and the car is rocked back and forth. It's not that big of a deal.

My husband physically "rocked" the car back and forth when it was in park from the back and yes, we then can hear the ad blue slosh, but it's not the same sound I hear. I am pretty sure once they "top off" the adblue tank today in the shop like they said they would, the sound will still be there. The only thing that semi-scares me is the mechanic said he can "feel" the sound on the adblue tank. I guess we shall see!
Something interesting, my husband asked if there were "baffles" in the adblue tank to help deter sloshing and the mechanic said there isn't and he's unsure as to why. I guess there are baffles in the gas tank? That seems like it would reduce the sloshing noise a bit. Just a thought.

Feels good, doesn't it? I'm glad I have you guys to vent to because my husband certainly doesn't want to listen to my #@$%.
Also, please know that I didn't mean to sound flippant at ALL when I said it was a bummer for you. I had no idea all of your problems and certainly feel you have WAY more to complain about than I do!! I genuinely meant that it was a bummer.
