No, I don't have anything same in the glovebox. The fan motor was brand new, the sound appeared long before the replacement.

Thanks for the idea! I'll try it when I have free time. Fortunately, I am already know how to remove the glovebox, I replaced the blower motor a few months ago.

Thank you! Fortunately, I knew about it. The conrod bearings have already been replaced. Thank you! I have VCDS, my first thought was to scan, but found no errors. I will try to look more closely around the Climatic, to see if the error is there.

Thank you for your answers! I don't know if it could be from the climatronic or not. Anyway, I had a similar problem in my previous car with automatic ac and it made a similar sound but higher. But this car only has Climatic (semi-automatic), and I don't know what it sets automatically. Thank you, I'll keep that in mind. I forgot to write one thing: the first time this happened, it only appeared after about 25-30 minutes (so I think the engine was already warm). A few months later hanneped after 10 minutes. Now 2-3 minutes. However, the length of the sound did not change (attached video). But not every day, he didn't do it today, for example.

Hello Guys, I hope somebody could help me. I looked for another such topic, but I did not find the same problem. I have a problem with my Octavia. Engine: 1.9 BXE, 2007. The problem only occurs in the morning after 2-3 minutes after starting. A knocking/ticking noise can be heard in the passenger compartment, probably from the driver's side (left side). I am attaching an audio recording. I also tried to make a sound recording from the engine compartment, but nothing but the sound of the engine could be heard. However, I don't know where the sound is coming from because it is so indistinguishable to me. After the sound appears in the morning, it cannot be heard again for the rest of the road. You can't hear it during the rest of the day either, even if I start the car cold again after eight hours of standing. The car has manual air conditioning, the dual mass and clutch have already been replaced, as well as the crank bearings. The sound is the same when the clutch is depressed and released (I tested this because I suspected the dual mass). The car is parked on a slight slope in front of the house for the evening (I don't know if that matters). If it matters: After starting, idling is normal, and the average consumption is 0.7L/H. After a few minutes, it adjusts to 0.5L/H. Please help me figure out what it is. I hope somebody can. postscript: Sorry If My english grammar was bad, I used google translator. lv_0_20230508151633.mp4
