maybe someone had this error , it`s something on adblue but I donīt know for sure. please help me

 

look for it on youtube , many solving problem channels out there

 

I had the same error, I got a message on my dashboard that there were some miles left to drive. Good thing the dealer was around and after diagnosis my dealer suggested replacing the whole adblue tank.
After a few months I ran into the AdBlue related error again and had to spot the temperature sensor.

I finally got sick of it and was afraid I might get an AdBlue error again somewhere on the road away from the dealer and decided to disable it completely. Used an OBD plug that I ordered from OBDTUNE dot com - it turned out to be much easier each repair - removal only software and took a few minutes, and cheaper than 2 repairs together. Team member Vlad answered all my questions and everything went smoothly.
