    Hello! I have a problem with ACM, namely the code 970C07 was first lit - the sensor readiness conditions before the angle were not ensured in a timely manner. The sensor in front of the catalyst was replaced with a new one and two weeks after the dpf filter burned out, another code 900C0B appeared, i.e. the signal value of A70 b1 (sensor at the catalyst inlet) is incorrect. After deleting the xenta of the fault, everything is ok until dpf is fired again and the situation repeats itself. Does anyone have any idea what to do to remove this problem?

    The second error is a corresponding dynamic test in the original diagnostic computer. And that's where I would start. I introduced some random data for this model to the simulation of the test on Star Diagnose, because of course the data of the damaged car is missing and it is not known what its completion is.

    So you can not do without the service because you have to log in to the Mercedes system?

    The test itself should fly even on an SD clone. Without logging into the network.

    Yes, I know, but it shows me that I must have some external data carrier

    Such a message is actually displayed when there is no on-line contact. Instead of real-time data transfer, a file is sent to the Mercedes, which is processed in their cell and sent back. This happens in different cases and I do not necessarily associate it with the current inquiry. It happens that some errors affecting the ecology require this procedure in order to be cleared. The manufacturer simply wants to know which customer and which car are operated in a way that pollutes the environment. If you have the option, throw in a screen or something else that may help to decode why the system wants you to prepare a data carrier.

    This part of Poland, inhabited by many Poles, is located almost 3,000 km west of Warsaw. When you have it on the way, please :)

    Well, that's more or less a matter of course. The system concluded that in order to repair the damage and reduce the possibility of its recurrence in the future, a software update in the controller was needed. In the case of an authorized service (and on-line contact), this type of process is automatic. If you cannot log into your personal account in the Mercedes database, you are probably in de - because the clones of the original service computer do not have access to program updates available as "patches" to fix the most common errors. I am also not able to remotely check if the software in the driver of your car is up-to-date.

    Maybe try to run the test yourself - if you succeed, you will know where you stand. Then, possibly, you will go to the software update to the Dealership.

    Hello.
    Buddy, tell me when you got over the 900C0B error, I have the same, I have already changed two NOXs. The error can be deleted, but after firing the DPF, the same thing again, and nibbled on non-stop burns. Doalsnie "cosmos"

Topic summary

The discussion revolves around issues with the Mercedes Actros MP4 Euro 6 related to ACM error codes 970C07 and 900C0B. The user reports that after replacing the sensor in front of the catalyst, the DPF filter burned out, leading to the reappearance of the 900C0B error, indicating an incorrect signal from the A70 b1 sensor. Responses suggest conducting a dynamic test using the original diagnostic computer or a compatible SD clone, as well as the necessity of logging into the Mercedes system for software updates to resolve recurring errors. The conversation highlights the importance of proper diagnostics and potential service intervention for persistent issues.
