09 ml320 bluetec I just added some adblue, but the "starts remaining" message has not gone away. Do I have to reset the service a or whatever through the cluster?

Help!

tbal

Filled her right up to point where no more fluid would go down lol... 12x 1.89L bottles...

The counter ## starts left went away, just the check adblue warning still there. I tried resetting the service item from the menu, but dont see a reset for the adblue. I saw a adblue screen which said Adblue ----- but you cant seem to do anything there...

Does it require star? Thanks a lot mercedes for this stupid adblue nonsense.

After driving it for 5-10 miles it is suppose to reset itself. I learns the new level and will remove the message from the instrument cluster. If it is still present then it will need to be reset why a SDS machine. Good Luck!

tbal

Correct! After a few miles it did go away. The tank has to get fully filled and than its fine.

Thanks again!

At what mileage your warning came up? I only have 2800 miles on my 2012 ML350 BTC and it just had "add AdBlue" came up. I did refilled it up but the warning is still there even after 15 miles of diving....

You should check with your dealer. There is no reason for the "add Adblue" message to come up at only 2800 miles. I suspect the dealer did not fill up the Adblue tank when they delivered the vehicle to you.

Taking it to the dealer tomorrow, i wonder if i have to take the car to the dealer every time i fill up AdBlue.....

mp0i

No, they probably didn't fill the tank on delivery. I have two Bluetecs and the Adblue system works just fine. I did have a recall on the ML last year for something in the Bluetec software but there was no problems with the level warning system. I fill the Adblue system every so often and tend to keep them on the "full" side to reduce sloshing and evaporation. Recently I have been letting the GL run low as I will being performing the 20,000 mile Adblue service on it in a couple weeks. My plan is to simply use my MightyVac (used for oil changes) to evacuate the Adblue tank and fill it with fresh stuff. I get my Adblue from my local auto parts store for about $15.00/2.5 gal so I can do this service for about $50.00 total.

I am planning to replace the adblue. Anyone know where/how to discard the old adblue?

dgiturbo

Good question. It's suposed to be a non toxic mixture of 70% water and 30% urea.
Don't hold me to this, and don't quote me, but pour it the same place you pee?

lbun

took it to the dealer today, after looking into the problem for 2 hours, as i was waiting for it, dealer said that i have to bring the car back it probably leave it for the day. As i was driving away the "AdBlue warning" went away but on the next start it did come up again. Some weird sh$t.....

lbun

Just picked up the car from the dealer after leaving it there for 2 days. Dealer says there is a glitch in 2012 ML350 BTC software and they are waiting for a new release to clear adBlue warning malfunction. Dealer says release supposedly has to come out in a week or so.....

Why?

tbal

Why?? There is no need. Its not like engine oil lol. Just top off...

mp0i

I suppose if you choose to top it off it will work for you. I tend to believe that over time the urea solution may concentrate due to minor evaporation of the water in the solution and perhaps form crystals inside the tank thus impairing the operation of the injection system. By evacuating it every two years (which is recommended by the manufacturer and corresponds with the reported shelf life of the urea solution) and replacing it with fresh Adblue, I believe that my vehicles will provide a greater degree of reliability over the long run. I plan on keeping them for a while. If one were only leasing a vehicle for a couple years then I would probably approach this maintenance item differently.

RobertG

If you dont use the vehicle and it sits for long period of time then I would see the need for draining the urea and refilling it with fresh stuff.
how often do you find yourself having to add the urea?

mp0i

I typically put some in every 7500-10,000 miles (works out to about every 6-8 months). I don't notice any 'sloshing around' so much and prefer to avoid getting the Adblue level low warning.

Ted Bagshaw

On the early MB model versions Add Blue Warning & top up must be done at a MB dealers on later models then you can just top up yourself and the system resets itself from the new level signal.
If you vehicle is older probably pre-2015 and has not been serviced at a MB dealer or somewhere where you have had regular software updates then it will not restart when it reaches zero. I think MB wanted to have the say in where you filled up with Add Blue.

Certainly this was the case in the UK other markets might be different.

Ivan Bianchi

Hi .. i am still new to mercedes i have to fill the add blue but there is a check engine is it normal when adblue is low check engine appears?

You are asking a question about a veh. we do not know that you own.

Please UPDATE YOUR PROFILE in USER CP to include the year, model (gas or diesel) and where you live.

I put adblue in with 17 starts remaining. The warning didn’t go off. But as I had put it in, I assumed (yes I know not to assume) that the warning would just run out and reset. However, it went to zero and the vehicle will not start. If I fill it all the way up will it start? Or is there a way to reset it myself? Help, please?

You'll need to reset the counter with STAR. Also it will be good idea to check whether adblue level sensor is working correctly.
