    So you unplugged the NOx and still the adblue level "jumped"?
    you checked the installation and it's ok, the fuses are ok, if you checked the above carefully and you are sure of it, there are two more options: the adblue level sensor itself or the controller in the pump.

    Hello.
    Problem has been solved. I do not know where the adblue in the control unit came from, but it was still there. I am only wondering where it came from if there is not a drop of urea in the entire pump and it was in the driver. I cleaned, sealed, assembled and it works!

    Interesting ... maybe the previous owner, if he didn't clean something, although the photo does not show perfectly well, but it does not necessarily have to be adblue, and congratulations :)

Topic summary

The discussion revolves around an AdBlue issue in a MAN TGX 440, where the AdBlue system has stopped functioning, and the user is unable to connect to it via diagnostic tools. The user reports three error codes: DIAG 2061-08, EDC 3822-04, and INST 8135-04. Various responses suggest potential causes, including a damaged probe or wiring issues, particularly around the AdBlue tank and its connections. Users recommend checking the wiring harness, the AdBlue level sensor, and the pump. Some mention that the problem may be linked to the NOx sensor or the control unit. Solutions discussed include inspecting and possibly replacing the wiring, sensors, or the pump itself. The conversation highlights the complexity of the AdBlue system, especially in Euro 5 and Euro 6 models, and the need for professional diagnostics in some cases.
