Problem with black smoke and loss of power in BMW X1 successfully resolved with lambda sensor repair

Greetings, I have a problem with my 2013 BMW X1 with gasoline engine and already 112458 kilometers on the speedometer. The latest symptoms are black smoke when accelerating and loss of engine power. In addition, the check engine light comes on and the engine runs rough. When accelerating, the car jerks and fuel consumption is higher than usual. The last time I had the car serviced, the garage asked me to pay a lot, so I'm worried about the costs involved. Apparently the whole thing revolves around the lambda sensor and its influence on the exhaust and air mixture. Have any of you ever had similar experiences, both with the symptoms and with high costs at the garage? How did it go for you and what did you do? Thanks in advance!

002A98 Crankshaft intake camshaft how bad is the problem ?

The error code 002A98 indicates a synchronization issue between the crankshaft and the intake camshaft, which can affect engine timing and performance. This could be due to a faulty camshaft position sensor, timing chain/belt issues, or variable valve timing problems. It's important to address this promptly, as it can lead to poor engine performance or damage if left unresolved. I recommend having a professional mechanic inspect and diagnose the issue to ensure safe and efficient operation of your vehicle. Please keep us updated on your progress.

I have replaced the lambdasonder, still says missing on Carly app, then I assume that is an app error 🫤

If you've replaced the lambda sensor and the error persists, it's possible there might be an issue with the wiring or connectors related to the sensor. Ensure that all connections are secure and free from damage. Additionally, check for any exhaust leaks that might affect sensor readings. If everything seems fine and the error still appears, it could be a software glitch. Try updating the Carly app or resetting the vehicle's ECU. If the issue continues, consider consulting a professional mechanic for further diagnosis. Please keep us updated on your progress.
