Alex is correct, any dealer will service it as it is a warranty issue. Should only take 4-6 hours to do the procedure correctly.

We now have over 3000 miles on our car after it was fixed a month ago. No more problems at this point. I hope that the issue is fixed permanently. Incidentally, our mileage on a 2300 mile trip in 8 days ranged from a low of 30.7 which was in very cold weather with a combination of winter blended fuel and biodiesel to a high of 37.9. Most tanks were 35 miles per gallon. Speeds were mostly between 65 and 77 mph. The computer usually showed 2.2 to 2.7 mpg higher than actual mpg. Car was very comfortable for the duration of our trip.

Received our GLK250 back today. New NOx sensor and additional software updates to the updated software. Now has 1500 mile, I hope it's fixed this time because we love the SUV. Three months old and we have only had use of the car for three weeks, the rest of the time it was at the dealer.

Alex Bel

Picked up today our 2014 GLK250. All was good during our short 250 miles trip from OH to MI. Dealer was nice, car was clean, with the same amount of fuel as before.

This is what was done according to Invoice:
- AdBlue was added.
- One NOx sensor was bad - dealer replaced BOTH NOx sensors ( 000-905-34-03) and Temperature Sensor (000-905-88-00) in SCR Catalytic Converter.
- Performed software update.
- Road test the vehicle (97 miles).

According to the dealer our vehicle was third with AdBlue problem in their dealership.

Alex,

Glad to hear you got your GLK250 back from the dealer. Sorry you didn't get to take it on your trip, however look at the bright side, MB-USA paid for the milage on the rental they provided you. A small consolation I realize, however at least you weren't stranded. That would've been bad.

Thanks for posting a summary of the work performed. That's helpful to all of us.

Good luck and I hope they got it fixed for you!

Best Regards,
Jim

Today I was shopping in the town where I bought my GLK. On my way home I noticed my engine light was on. Turned around and went to the dealer. They put me in a loaner car for the third time. The ad blue warning was not on yet. They said it would be Monday before I knew anything. I am just so disgusted that this keeps happening.

skelly5282

Took possesion of my brand new GLK 250 on Nov 16, 2013.On the drive home from the dealer that same day,the CEL came on.Immediately phoned the dealer and was told to check the gas cap.Instead I just refuelled the car and the CEL was no longer on when I re-started the vehicle.Have driven it approx 2000kms since that date.Yesterday,the dreaded CEL came on again.I figured likely the same issue as I had originally,so I stopped and refuelled and made sure gas cap was on tight.Unfortunately this did not resolve the issue.This morning,while driving,the AdBlue warning came on,and the CEL remains on.Since today is Sunday,the dealership is not open.Hopefully I can get the vehicle in early next week.Sadly,I will have to drive over 100 miles to the dealership and have to take a day off work to get it looked at.

Are there any updates on this issue?Does anyone know if MB actually has a solution for this problem?

thanks

mlljohn58

Skelly5282,

They have replaced my entire blue tec system and redone my software and my engine light came on Friday for the third time. I don't know if the solution works for every car. They haven't told me this time what the problem is.

107123210

Looks like we are up to 23 Adblue system failures now. Will update link in a week or two.

https://mbworld.org/forums/5861488-post177.html

Skelly's car was delivered on Nov 16. By that time, MBUSA, MBCanada and dealers had the software update. If it was not applied, that could explain it.

But if it was applied, then perhaps the problem is not solved?

BigBoeing

Balticgreen previously indicated that MB-USA automatically performs any necessary software updates as the vehicle is prepared at the VPC, and it's re-checked for any necessary updates preceding delivery at the dealer. I presume the same procedures apply with MB-Canada.

Quite unfortunately, it's beginning to sound as though MB hasn't resolved this problem. And I'm due to take delivery later this month on my GLK250. Not good.

Best Regards,
Jim

It's very interesting for me to read what has been posted about adblue problems with the MB 250 GLK Bluetec.

At first, i am from germany and my english isn't similar to yours. So i hope you excuse me. Even the language is different, the adblue problems aren't.

I got by GLK 250 Bluetec from an MB subsidiary in germany, with registration date of 12/2012 as a second hand car with already 32.000 km, at 09/20/2013. The car has been owned and used by Daimler before. I do not have any information about problems during this period.

After about 1000 more km at 10/07/2013 the adblue warning appears in the display. Different from the usa-version the displayed warning in the german version says: "No more starts after 800 km"; Then the countdown starts.

At 10/09/13 the car got it's first visit of an MB dealer near my hometown.
First reaction there: maybe less adblue. So they refilled it, even it wasn't empty. Result: nothing happened. The adblue error remained. No possibility for the mechanics to delete the error memory.

Because of my time schedule an other visit at the next day was necessary. At 10/10/13 they checked the AdBlue-System and told me, they have been caused by MB to update the software of the motor control unit. Several hours later everything was done. The error memory was empty, no more warnings in the display.

Ten days and a some hundred km later, at 10/20/13, the AdBlue Warning appeared again. "No more starts after ... km".

10/21/13 next visit at the MB dealer. Software was already updated. AdBlue refilled. So what? I was told to leave the car for a check in cooperation with the technical division of MB.

After two and a half weeks later, on 11/07/13, i was informed they may have found the reason for the problem with the adblue.
Several components have been changed in the meantime until they identifyed the motor control unit as the "bad boy" which was replaced through a brand new one.

After test driving at the same day and at the next day again, to make sure the problem is resolved substantial, I got back my GLK250 on 11/08/13, promised everything is fine now.

Well, i hoped so. But it is a BlueTec.

I wasn't disappointed by BlueTec.
On 11/30/13, after three weeks driving without any problems, the "AdBlue Warning" in the display came back to me.

Of course a new visit at the dealer on 12/02/13. No explication. Same procedure than before....

I don't want it any more. I close this "GLK 250 BlueTec capital". The car goes back to the MB subsidiary and i get my money back.

No more BlueTec ever!! I promise.

BigBoeing

w-stedde,

Thanks very much for your post. You answered a question I've had for some time, to wit: is this AdBlue problem unique to the USA and Canada, or has it been a universal problem with the GLK250?

I'm curious regarding your "lemon laws" in Germany. What does the law in Germany state regarding returning a defective vehicle to the distributor (what we refer to as the "dealer" here)? What is the threshold that must be met in order to return a car to the local distributor for a refund? Are you entitled to a full refund for the original price you paid for your car?

I'm sorry to hear of your troubles.

Best Regards,
Jim

mlljohn58

Jim, what is the lemon law in your state? Mine is three times. I am curious as to what Mercedes will do with mine as this is my third time in three months.

Alex Bel

Do the owners of E250 BlueTEC sedan have the same AdBlue problem?
I could not find any complain so far. Do you?

w-stedde

Hello Jim,

had to look for some terms you used because they aren't so common for me.
To have the opportunity to reverse transaction of a sales contract you have to enable the dealer or distributor to remove defects at least two times. If he doesn't succeed the customer can decide to give the product back and to get his money back. That's a general regulation, not only for cars. Depending on the situation the customer has to pay a compensation for use.
That's what I know. But I'm not a lawyer.
In my case the agreement with the MB subsidiary has already been arranged the way as discribed.

Hope others will be succesfull in those cases, too.

If you finde any misspelling, keep them

Many greetings from Germany.

We know the delivery date but we don't know when it was produced, when it came through VPC (or whatever Canada calls VPC), or how the long the dealer had it before selling it. Skelly may have bought a car that was in dealer inventory for a while and was never updated. Hopefully skelly will come back and clarify the timeline.

If the update was applied, my question would be whether it was applied correctly? We have heard from a small number of people who needed the same update performed again and then it was fine. This suggests that the knowledge of the service techs may also play a role and a failure after update does not necessarily mean that the available fix does not solve the problem.

I can't speak for Canada either. MBUSA is doing it at the port but that depends on the car having come through VPC after late October. If it wasn't done at VPC then the dealer should check for updates, but did they? And did they do it correctly?

mlljohn58

My dealer did the update twice and sent the info to mercedes, who declared it updated. It is back at dealer now. I am waiting to hear what the problem is this time. I am scared the update doesn't work.

BigBoeing

Here's an interesting thought regarding any pre-delivery updates at the VPC's and dealers:

It's my understanding that this fix is far more than simply a software update. To the best of my recollection somebody here stated it's a software update followed by a 95-mile test drive, followed by re-callibration. If that's truly the case then I don't see them doing this fix at a VPC as they're not about to put 90 miles on a brand new, yet undelivered vehicle. Moreover, I seriously doubt the dealer is going to put 95 miles on a yet undelivered vehicle.

Accordingly, I see them passing this problem on the customer who then has to return the vehicle to the dealer should the problem arise.

Anybody??

Best Regards,
Jim

xcowdoc

Jim,

Are you going to take delivery of your vehicle considering all of this? Even though mine seems to have been fixed the first time, I am wondering when the problem will arise again. I have put nearly 3000 miles on mine since the fix.

BigBoeing

Boy xcowdoc...you're asking a great but difficult question, given my previous statement that "I don't want to buy a problem." I paid what I presume to be a nonrefundable $1,000.00 deposit when I ordered our GLK250 in October, and it's due here this month. I was truly hoping they'd get this problem definitively resolved during the interim, and thus have been watching this thread VERY closely. I'm now truly beginning to wonder if there's a fundamental design flaw with the entire AdBlue system. That would be REALLY bad news.

I'm truly torn on this matter as excluding the AdBlue/CEL issue, everything I've read says this is a beautiful vehicle. I guess I've got a few more weeks to lose sleep over this??

Thanks,
Jim

skelly5282

I can't tell an exact date of manufacturing of my GLK. The door sticker says 09/13. So hopefully the newer production does not experience similar problems. Disappointed with an otherwise fine vehicle. I have emailed Mercedes Benz Canada but have not received a response yet.

107123210

This is the response I got from MB Canada when I expressed my concern re the Adblue problem:

Might be interesting to ask your dealer if they had applied the software update before delivering the car to you.

w-stedde's case is interesting, in that it appears to be on an early 2013 model car.
My 2014 car has only done 80km - not much of a test! I have a friend who has had his 2014 glk for longer (from before the software update date). No problem so far. I imagine many glks are trouble free. But MB must be pulling their hair out trying to resolve this problem.

107123210

Sooner or later, one of these will probably be available for the gLK250!

http://www.diag-x.com/Adblue_Removal

I did a search for the Adblue or DEF problem but excluded GLK or Mercedes. Amazing number of hits. All types of cars and trucks are having this problem and have been for several years. I saw stories much like the ones here, but with VWs, Audis, Peugeots and even GM diesel trucks. Here is one GM story with a happy ending.

bugelrex

no way anyone is doing this until warranty expires!
