P1345 / camshaft sensor

Moin dear community, I had rolled the days at night in traffic jam (longer time in the first gear, often uncoupled and again, standstill… jam stop) at once engine drop-outs. U.U. only from 1500RPM or if you (at the start) caused load by coupling in. Flight also started the MKL. Briefly breathed through and quite firmly pondering… did everything there to read out and at least see if I reach something myself. So read out and just P1345, briefly googled, camshaft sensor. f and the sensor once removed, check. Nix seen, reinstalled. Bitsl on the cables. Error deleted, continued. Couple hundred meters later (still in traffic jam, therefore several minutes later) same problem. So again bonnet on, this time only the plug re-plugged several times. The next 400km was everything ok. Had then the days nen bissl Caramba injected into plug and socket. Today very similar traffic jam and again the same problem. new (still good oily), the next 50km (up to home just) everything ok. Does not feel for me after a sensor defect, but rather cable / contact problems. But what do you say? 1. Is in the first gear clearly under 1500rpm longer time loaming particularly violent (special vibration frequencies?) for plug contacts or any other in the motor? 2.) Sensor possibly nevertheless defective? 3.) Is the 1,9er NB sensor really compatible with the 1,9er NBFL? Remove the sensor from my other NB and put it in the glove compartment. I depend on my car tomorrow. Greetings Erinya
