Hello together, I have a persistent problem with my B14XER and hope that someone here in the forum might have had a similar experience or have an idea what it might be. To the problem: There is a grinding noise that occurs to my hearing about half engine speed. The entire secondary drive has already been renewed, including climate compressor and alternator. If I take off the belt, the noise will continue to persist. It sounds short grinding a The crankcase ventilation as well as some other components have already been changed, but the noise remains. That makes me rather perplexed. Interestingly, I have heard this noise already on several Corsa models, but I have not yet found a clear diagnosis. Has any of you had similar experiences or an idea where the problem might lie? I would be for ever Thank you! Here is a video https://youtube.com/shorts/wQ-1aCfsoFc?si=d3pudB9lfkG31Njw Best regards
