Hello, since the last time I was helped so quickly, after I finally uploaded photos of the component in question, here is a question with media support: What has my engine been doing for a short time for a noise that it probably should not do? Below you will find an audio file with the noise. The engine is a B5252FS. The noise comes sometimes, then it is also gone, without seeing a reason. It is obviously not related to the engine temperature. Yesterday morning it came right after the start, i.e. with cold engine, before that it was there after the departure from the highway, so with warm engine. From a speed of about 70 km/h the noise is too quiet, i.e. I usually don’t get along when it appears … Many greetings Jochen
