Hello, can anyone tell me what’s wrong with the engine.https://youtu.be/NX-cETm5-NI I’ve been to the Volvo dealership twice, but they couldn’t really tell me where this “blechner” noise comes from. The clutch excluded them. The defective camshaft sounds somehow different? This noise is also not regularly/permanent to hear. Otherwise, you don’t notice anything about it when driving. No error is shown either. I’m really desperate.
