Stalling can send you in circles if you guess at parts. P0340 relates to the camshaft position sensor circuit, but the code alone doesn't prove the sensor is bad. This clip is a starting point for diagnosis, not the whole answer.
This short DirtyKurty video covers a stalling issue on a 2001 BMW 530i with the M54 engine and diagnostic trouble code P0340. The generic P0340 description concerns a camshaft position sensor circuit, but several electrical or mechanical causes may need to be considered. Search terms such as E39 530i stalling, BMW M54 cam sensor circuit, and P0340 diagnosis point to this clip. No replacement part or final fault diagnosis is asserted from the title alone.
