Finally, the problem has been solved
A faulty sensor was the problem
However, it took 3 sensors to find a working one (the first 2 purchased at the local dealer)
A Third OEM part from a remote stealer solved the problem
I strongly think the local BMW stealer is selling Chinese BMW spare clones or something like that (not the first time this has happened with other parts)
Even some BMW Motorrad services have been Tunnel Rush made with HiFlo and Mahale filters as I have seen
Is this something common to happen with the BMW dealers to sell non-OEM spares?
Have someone else experienced the same issues before with the stealers?
Sensor Issues: The camshaft position sensor could be malfunctioning or faulty. This sensor helps the engine control unit (ECU) determine the position of the camshaft to optimize engine performance. If the sensor isn't sending the correct signal, it can affect engine performance and efficiency.
