Need alitte help or direction

Hey Guys and Gals,

I have a 2014 GLK 250 BlueTec , I had dealt with the dealership on the OS sensors and they still keep messing it up, and now there is a Permanent code posted , and now the issue is my Adblue has started its countdown for # of starts.
Apparently I cannot clear the adblue code, because of the Permanent code from the OS sensors.

1) I tried disconnecting battery for 10min etc, didnt change anything...

Thanks in advance.

This place is a joke.
This is just the beginning of the miserable ownership of a Mercedes diesel. Get rid of it. If you like the car, buy a GLK350 (gas) you'll be much better off.

Do you live somewhere with emissions testing? If not get the codes cleared by a euro shop with Star diagnosis (not Mercedes) might cost you 100$, then pay a company like OETuning to fix your ECU and you will never have issues again. That costs around 1000$.

I actually love this car , I have many other MB's and I understand the ownership elements of each type/brand etc.. I got MB to replace the exhaust and all under emissions warrently, but the dealership is being a dick about this part, and its just not worth my time to argue with them. If it was under warranty etc, I would fight the battle, but its not worth it..

Just looking for what I can do to get it all cleared..

I plan to mod out the adblue anyways.. but need to get past this crap..

Do you know if it has to be a Star Diag ?? I only have 3 starts remaining, so I called a local Euro shop, and he said he uses a 3rd party machine, and has a couple, but NOT a Star.. and I dont want to end up stranded... :-)

pretty sure it needs to be the star to reset the entire system at this point. I found a local mobile guy that has a laptop with star to do it for me.
got it reset and got the tune that I did myself with the OEtuning software and obd2 adapter they sent.

Might be a good idea to just contact OETuning (or your favorite tuner) and get the flash load tool shipped to your house. You can likely get a discount being a MBWorld forum member, just ask for the discount.

In all, I think I paid $750 but I also paid an extra $100 for the AdBlue delete. You likely don't need it, since rewriting the software will reset the ECU. But it helps not worrying about the DEF system breaking down later (usually one of the heaters) and causing other issues.
