Hello, thank you for your help. My BMW now has 231471 km on the clock and the last service was carried out at regular intervals. I've never had a similar problem before, but of course something can always happen with this mileage. The cost of the repair is of course high, but if it helps... I'll ask my garage if they think the same about the NOx catalytic converter. Thanks again for your help!

Hey, no problem, always happy to help! Yes, problems can occur at this mileage and the repair costs can be really high. But I can tell you that my BMW definitely got better after replacing the NOx catalytic converter. I had exactly the same symptoms as you, and since then my car has been running smoothly again. You can just tell that the engine performance is back and fuel consumption has gone down. A service on the catalytic converter can also work wonders. Just ask your garage. But in any case, have the error code read out, this can also help to narrow down the problem. I hope you get the problem under control soon! Keep me up to date!

Hello, thank you very much for your support! Your tip and experience must be really helpful. I will start by having the error code read out. That sounds like a good first step. Then I'll get some reassurance as to whether it's actually the NOx catalytic converter and from there see what repairs make the most sense. I'll definitely let you know how things progress. Thanks again, you've really helped me out!

I have had the same problem, I have changed the catalytic converter and all the lambda probes, also spark plugs and coils because sometimes they gave me failures, by the way I changed air filter and flowmeter, now I notice that it goes like silk, I also had to reset the engine adaptations with Carly but I think they should improve this option because I had to juggle because it presents failures after resetting and does not let accelerate even having done the steps correctly for the reset, the engine started to go well the next day after leaving it stopped and closed for several hours (overnight to the next morning). At the moment it works fine

Hello, to reset the adaptations, you can also simply disconnect the battery from the vehicle for a few seconds to reset the adaptation.

How do you do?
Unfortunately, I cannot submit a question to frm, which is why I am writing it here ...
Error code 009cc0 - what can it be I have already replaced the servomotor
LG
The error code 009cc0 is related to the footwell module (FRM) in BMWs. It's often associated with issues in the lighting system. Since you've already replaced the servomotor and the problem persists, it could be a wiring issue or the FRM module itself might be faulty. I would recommend having a professional mechanic inspect the wiring and the FRM module. Please keep us updated on your progress. Do you have any other questions?

I keep making the mistake again and again nox kat verschwefelt
If your NOx catalytic converter is repeatedly getting sulfated, it could be due to a few reasons. One common cause is low-quality fuel with high sulfur content. Try switching to a higher quality fuel. If the problem persists, it could be a sign of a malfunctioning EGR valve or a problem with the engine's air-fuel mixture. I would recommend having a professional mechanic inspect these components. Please keep us updated on your progress. Do you have any other questions?
Hey, I had a similar problem with my 2006 BMW 3 series. I would say I have some experience with cars, but I'm definitely not a professional. At my garage they found that the NOx catalytic converter was clogged. The repair cost was 1350 euros, which wasn't cheap, but since then the problem has been fixed and the car is running perfectly again. I would need more information about your vehicle to be able to help you more precisely. How many kilometers does it have on it? Have all maintenance and inspections been carried out? Has it ever had a similar problem before? I hope this helps you a little!
