Hello, I am interested to know if it is possible to code the ACC (Adaptive Cruise Control) so that it does not enter standby mode. My car is a Skoda Superb 2018. If anyone has done such a modification or knows if this can be done with VCDS, please share information. Thank you in advance!

Thank you for sharing the repair kit link. As we can see from iv3-skoda's experience, who successfully resolved the issue with a new sensor for about 275 euros, replacement is a working solution. If you decide to test the repair kit from AliExpress, it would be very helpful for the community if you could share your results and experience with it.

Thank you for sharing your experience, @iv3-skoda It's interesting to hear that cleaning the sensor didn't help in your case and that the error reappeared shortly after. I understand that this was quite frustrating for you, as the check engine light was quite disturbing. I'm glad you found a solution by purchasing a new sensor from a local car parts seller for around 275 euros. I'm happy to hear that everything is fine after the replacement. If you're willing, you can share more details about your experience, which could help other users with a similar problem.

Interesting, in my case the regeneration doesn't start automatically after clearing the error as you mentioned. This might indicate that we have different software versions or that our NOx sensor issues are slightly different, even though the error code is the same. Please share your results after cleaning the sensor - it would be very helpful to know if this approach works. This information could help other owners facing the same NOx sensor issue, especially given the high replacement costs at official dealers.

While cleaning the NOx sensor with radiator cleaner has been shown in some YouTube videos, I would be cautious about this approach. NOx sensors are very sensitive electronic components and using harsh chemicals could potentially damage them further. If you want to try cleaning, I would first recommend checking if there's any visible debris or deposits that could be carefully removed. However, given that this is a critical emissions component, the safest options remain either proper replacement with a new sensor or having it professionally serviced. Have you had any professional diagnose the sensor condition?

Thank you for your response, @Marioo . So you're only getting the P2200 error (NOx sensor electrical malfunction) and it returns every 2-3 days. This is different from some other cases where the error reappears almost immediately after clearing. Are you using any diagnostic software to clear the errors?

Hello @Marioo, which error code appears in your case - P2200 (NOx Sensor 1 Bank 1 electrical malfunction) or P2209 (sensor heating circuit issue), or both? Also, could you share how often you need to clear these errors and whether they reappear immediately after clearing or it takes some time?

@iv3-skoda I sent you a private message.

Thank you for the information, @iv3-skoda. I appreciate you sharing this with us. It's interesting that the error reappears so quickly for you. This definitely suggests a more serious problem than what I'm experiencing. The link you provided for the replacement NOx sensor looks promising. I'm glad you've found a potential permanent solution. It will be very helpful to hear about your results after you replace the part. Please keep us informed about how the replacement goes and whether it solves the problem. Your experience could be valuable for others facing similar issues, including myself if I decide to take further action in the future. Good luck with the replacement, and I look forward to hearing about the outcome! By the way, are you from Bulgaria? It would be great if we're fellow countrymen and could share experiences at a local level.

Hello @iv3-skoda, Thank you for your question. Unfortunately, I haven't found a permanent solution to the problem yet. Here's what I can share from my experience: 1. In my case, the error appears rarely, usually during highway driving. 2. I use VCDS for diagnostics and periodically clearing the error code. 3. Since I mainly use the car for highway trips and not very often, this temporary solution with VCDS works for me for now. 4. I'm still considering whether to take more serious steps such as replacing the sensor, consulting a specialist for possible coding, or disabling the AdBlue system. If you have VCDS or a similar diagnostic tool, you can monitor the sensor's behavior in more detail and clear the errors when needed. If you decide to take any action before I do, I'd be glad if you could share the result. I hope this information is helpful to you. Good luck with resolving the problem!

@310golfr Thank you ! Please provide me with information so I can try unplugging the socket and plugging it back in. Please provide me with information on coding.

Hello @dlazar, Did you fix your car ? I also have the same problem with my Skoda Superb.
