I am asking for help. The situation is as follows, I have a 2025 Octavia with a mild hybrid engine. Mileage 13,000 km. After driving 6,000 km, the alternator belt started to squeak, especially noticeable on a cold car in the morning, and most of all in humid weather. Recently, the belt was replaced with a new one under warranty, so the problem has not disappeared. The Skoda representative reasons that he does not hear anything, although I had attached a video with obvious sound. I am attaching the audio recording here as well. Even in humid weather, not only can you hear the belt squeak, but you can also feel the jerking when running, especially in 2nd-3rd gear and at rpm between 1500-2000. It's very difficult to deal with Skoda, when they take the car for a while they can't record everything and feel the jerking. This is driving me to despair. The AI is mostly pointing towards a tensioner problem. Thanks in advance.I am asking for help. The situation is as follows, I have a 2025 Octavia with a mild hybrid engine. Mileage 13,000 km.
