From what ive seen of this fault, where refilling doesnt make the warning go away, its the nox sensors going out of calibration. Most people with the computer just tell it to reset the sensor values or tell the car the nox sensors have been replaced and then restart the car and it goes.
You're absolutely right! The **NOx (Nitrogen Oxide) sensors** in diesel vehicles like the **Mercedes C200d** are critical for managing emissions, and they often cause issues when they fall out of calibration or malfunction. If refilling the **AdBlue** doesn’t clear the warning, it’s often due to a problem with the NOx sensors. Here's a more specific approach based on what you mentioned: ### NOx Sensor Calibration or Reset Steps: 1. **Diagnostic Tool Capabilities**: Ensure that your diagnostic tool (such as your **Topdon ART800 OBDII**) has the capability to reset the NOx sensor values or perform a sensor adaptation. Some advanced tools or Mercedes-specific tools like **Xentry (Star Diagnostics)** can perform this task more reliably. 2. **Reset the NOx Sensors**: - Go to the NOx sensor reset or calibration function within the diagnostic tool. If your tool supports it, choose the option to reset the NOx sensor values. - If there’s a specific option to "tell the car that the NOx sensors have been replaced," select that as well. This forces the ECU to recalibrate the sensor readings. 3. **Restart the Engine**: Once the NOx sensor reset is complete, turn off the car and restart it. The warning light should go off if the sensor values have been successfully reset. ### Other Considerations: - **NOx Sensor Replacement**: If resetting the sensor values doesn't solve the issue, the NOx sensors might be physically faulty and need to be replaced. Since the sensors work in extreme conditions, they do wear out over time. - **AdBlue Injector Check**: If you're resetting the NOx sensors but the problem persists, also consider checking the **AdBlue injector** for any clogs or issues. A malfunctioning injector can cause improper NOx readings, even if the sensors themselves are functioning correctly. - **Software Updates**: As mentioned earlier, make sure your vehicle’s ECU has the latest software updates. Mercedes sometimes releases updates to address sensor calibration issues or refine the emission systems. With the right diagnostic tool, resetting or recalibrating the NOx sensors is often a quick fix for the "engine not possible" warning light related to the emission system. Keep us posted if this approach resolves the issue!
Hi mate can you help me I have a spanner engine management light and adblue on dash have 50miles left on the clock but I have been to more the 5 garages the plug in the scanner tool try to rest the light but all of them have said same thing your van is not letting the scanner read anything on the van no codes are showing what can I do
It sounds like your van’s diagnostic system might be having trouble communicating with the scanner due to a few possible issues. Here are steps to help troubleshoot and hopefully get those lights reset: 1. **Check the OBD Port**: - Sometimes, the OBD port itself may be dirty or loose. Ensure it’s clean and securely connected when plugging in the scanner. If you see any damaged pins, that could be the issue. 2. **Battery and Electrical System**: - Low battery voltage can sometimes interfere with diagnostics. Make sure your battery is fully charged and check the grounding connections around the battery and the OBD port. 3. **Try an OEM or High-End Diagnostic Tool**: - Some vans require specific diagnostic tools that are more compatible with their onboard system. Since the generic scanners aren’t reading it, you might want to try an OEM scanner or a high-end tool (e.g., Bosch KTS, Mercedes Xentry for Mercedes vans, etc.). Dealerships or specialized garages will often have these. 4. **Fuse Check**: - Some vehicles have an OBD fuse that can blow and cause communication issues. Check your owner’s manual to locate and inspect the OBD fuse and replace it if needed. 5. **AdBlue Reset Process**: - For AdBlue issues, some vehicles have a specific reset procedure after refilling the AdBlue tank. This might involve turning the ignition on and off several times or a particular driving sequence. Check your van’s manual or look online for your specific model. 6. **Software Update**: - Certain vans may have issues that require a software update from the manufacturer. A dealership can check if there’s a pending update that might resolve this. 7. **Wiring Inspection**: - Faulty wiring or connectors between the ECU and OBD port can cause communication failures. This could require a more in-depth inspection by an auto electrician. If you’re down to the last few miles before the van stops due to AdBlue, it’s best to contact a dealership or a specialist who can perform an emergency AdBlue reset. If none of these options work, they may also have advanced methods to get your van into "limp mode," allowing you some more mileage temporarily.
@@SanuMotorswithCharlie thanks for responding to me its the same van like in the video 2019 vauxhall vivaro i got my battery checked from a garage they was saying the power is low but the diffrent garages have pluged in scanner like topdon launch but same outcome its not showing any codes in the system but when they go to reset adblue they saying its not communicating with the scanner @sanumotorswithcharlie

Having similar issues on my van . OBD reading came up as nox senor bank 1 replaced with OEM part as Merc was wanting £500 issue has now returned ad blue malfunction now wondering whether OEM part is faulty and as sprinter are on a nox senor recall don’t want to throw money away 😢
I'm sorry to hear you're having trouble with your van, especially after replacing the NOx sensor. It's frustrating when an issue like this persists, especially with the added complexity of AdBlue systems. ### Possible Issues and Steps to Consider: 1. **OEM Part Quality**: While OEM parts are generally reliable, there's always a possibility that the replacement sensor could be faulty, especially if the issue reappeared shortly after replacement. 2. **Sensor Installation**: Sometimes, a faulty installation, such as a loose connection or improper seating, can cause the system to malfunction. It might be worth double-checking the installation or having it inspected by a professional. 3. **Software Update**: Modern vehicles, especially those with complex emissions systems, often require software updates when components like NOx sensors are replaced. If your van hasn't had a software update since the sensor was installed, this could be the cause of the issue. 4. **Related Component Issues**: The NOx sensor is part of a larger emissions control system. If there's an underlying problem with another component (such as the AdBlue injector, SCR catalyst, or wiring), it could cause the sensor to throw a fault code. 5. **NOx Sensor Recall**: Since you mentioned that Sprinters are on a NOx sensor recall, it would be prudent to contact your local Mercedes-Benz dealer to confirm if your van is part of the recall. If it is, the dealership might replace the sensor at no cost, potentially saving you from further expense. 6. **AdBlue Malfunction**: The AdBlue system is closely linked to the NOx sensors. If there's a malfunction, it might not necessarily be due to the sensor. Issues like incorrect AdBlue concentration, clogged injectors, or even low levels (despite what the gauge says) could trigger similar warnings. ### Next Steps: 1. **Contact Mercedes-Benz**: Check if your van is included in the NOx sensor recall. If it is, arrange for the recall work to be done. 2. **Diagnostic Check**: Before replacing any more parts, it might be worth having a thorough diagnostic check by a specialist. They can ensure that the sensor is functioning correctly and that there aren't any other issues with the system. 3. **Software Update**: Ask if your van requires any software updates related to the emissions system. This could resolve the malfunction without the need for further part replacements. 4. **Consider Professional Help**: If you're not comfortable doing further diagnostics yourself, it might be time to bring the van to a specialist who can give you a detailed report on the issue. By following these steps, you can avoid throwing more money at the problem and hopefully get to the root of the issue without unnecessary expenses.
Thank you for your insightful comment! You're absolutely right about the importance of cleaning the injector first and then bringing the engine to temperature to ensure the AdBlue pressure is within the correct range (5.5-6 bar). In this case, I skipped that step based on my past experience, but I agree that understanding the vehicle's history and the root cause of the issue-like running out of AdBlue-would have been crucial. I appreciate your advice and will definitely keep it in mind for future cases. Thanks again for sharing your knowledge Thank You
