Regeneration attempt due to short distances, last had 10tkm at once during vacation time. Only has to go out on the highway. Hence the error with the Nox sensor.

Hello Orhan60, It sounds like your vehicle might not be completing its diesel particulate filter (DPF) regeneration cycles due to mostly short distance driving. This could indeed cause issues with the NOx sensor. I would recommend taking your vehicle for a longer drive at highway speeds to allow the DPF to regenerate. If the error persists, it might be best to have the NOx sensor and DPF checked by a professional mechanic. Please keep us updated on your progress.

I'm not worried, I'm a mechatronics engineer myself, it's not my first BMW. Check engine light stays off. No noticeable loss of power. Also no symptoms that the particle filter is clogged. But I'm keeping an eye on it. After all, a BMW without a fault in the system is definitely not a BMW. The sensor is available from a Bmw parts dealer I know for approx. 240€ original. I'll replace it if necessary.

Hello Orhan60, It sounds like you have a good handle on the situation. It's great that you're keeping an eye on it and have a plan in place. Please don't hesitate to share your progress or ask if you have any further questions. Safe driving!

Hello Dubesset, Even if you're not experiencing any noticeable symptoms, a lambda probe error could indicate a potential issue with your vehicle's emission system. It's possible that the sensor is failing intermittently or not reading accurately. I would recommend having it checked by a professional mechanic to ensure your vehicle is running efficiently and not causing unnecessary harm to the environment. Please keep us updated on your progress.
I am happy to take note of it. I'm just wondering why you think I'm not professional enough? Are you professional if you have a workshop and the training for it? Or do you have training and no workshop? I bought Icarly so that I wouldn't have to carry my laptop around with me all the time and have a way of troubleshooting abroad. 😉 They wanted feedback on my error and I gave it. If the error never appears again, I have made the unnecessary search easier for many people.

Hello Orhan60, Apologies if my previous message gave the wrong impression. Your knowledge and expertise are evident in your posts, and your feedback is indeed valuable to the community. The advice to seek professional help is a general guideline for all users, as not everyone may have the same level of expertise. Your contributions are greatly appreciated and we look forward to hearing more about your experiences and insights. Safe driving!

Hello Felix, If the lambda sensor has already been replaced and you're still experiencing issues, it could be due to a problem with the fuel system or a vacuum leak. These could cause the air-fuel mixture to be off, leading to the jerking you're experiencing during acceleration. I would recommend having these systems checked. If you're not comfortable doing this yourself, it might be best to take your vehicle to a professional mechanic. Please keep us updated on your progress.
