Hey, thanks for your answer! Well, mine now has about 214780 km on the clock. Everything was fine at the last service, but that was a while ago. It seems that, like you, I'm probably going to get a not-so-pleasant bill from the garage🙄. It's annoying, but that's the way it is with older cars, isn't it? Best regards back!

No problem, man! Seems like you're dealing with the same problem I had back then. With the mileage, it's definitely possible that your NOx catalytic converter is at the end of its rope. The symptoms certainly fit. Not nice to hear that the bill is probably going to be high again, but better to take care of it before it causes more serious damage, right? My advice: off to the garage and let the experts take a closer look. It may be annoying, but after that your Bimmer should be running smoothly again. Cheer up, you'll be fine! Best regards!

Hey, thanks for your advice! I will definitely visit a garage. I just hope they fix it so that I can enjoy my Bimmer for a few more years. After all, it holds a lot of great memories. It's no fun, but you're right, I need to take care of it before it gets worse. Well then, I'll let you know how it goes. Have a nice day!

What is INPA or ISTA? I have no idea right now
INPA and ISTA are diagnostic software tools used by BMW to troubleshoot and diagnose issues with their vehicles. INPA is more of a basic tool, while ISTA is more advanced and comprehensive. However, using these tools requires a certain level of technical knowledge and they are typically used by professional mechanics. If you're not familiar with these tools, it's best to let a professional handle it. Do you have any other questions?

Hi there, I've been through a similar problem with my 2010 petrol BMW 1 Series. I am by no means a car expert, but more of a "regular workshop visitor". In my case, it was the NOx catalytic converter, which was heavily loaded or aged. I had it checked at the garage and then had to dig deep into my pockets - it cost €1350. But without the replacement, the symptoms would have remained. Can you give me more information about your car (mileage, engine, etc.)? Then I might be able to tell you more. Greetings!
