thanks will try

Hello, does anyone know what needs to be replaced/repaired? In winter mostly my back windows are getting really foggy and AC is not working properly. Once I do the calibration it is fine for like the next start of the vehicle. I am also including screenshots from VCDS errors. Thank you for any help.

Hello Marky, would you know the number of the part, so I can check?

Hello, I'm experiencing a problem where I notice an unusual whistling sound when accelerating, especially after starting. This sound usually disappears after repeated hard acceleration. Unfortunately, this sound reappears in another starts of the vehicle. I am attaching 3 videos showing this sound. Do you know where the problem could be? Skoda Superb 3, 2.0 TDI. Approx. 240k km. Thanks! IMG_0302.mp4 IMG_1156.mp4 IMG_1157.mp4

Alternator clutch is also changed now, no changes at all. Still the same issue, maybe alternator is faulty..I don't know what else it could be the belt is changed to see if the sound stops, but unfortunately the sound still appears

I will check. Thanks

No, never on idle.

Hello, could someone advise? The whistling sound occurs at high rpm after starting. The sound stops as soon as I increase the rpm a few times while driving. At idle, this sound does not occur. The alternator belt and tensioner pulley have been replaced, but the problem still persists. 2.0 TDI. 235k KM . IMG_0302.MP4

Strange, they just gave me a new one, and told me that everything should be OK...

No, never on idle even when I rev the engine. Only once the car is moving.

Hello, Thank you. It can be heard in the end of the video (sec. 3).

Hi, I would like to ask if anyone knows what this whistling sound means, which only occurs when the engine is cold and only at higher RPM and then stops. If the engine is warm the sound does not appear. Now the car is after replacing the alternator belt and tensioner pulley. The problem still persists. I have attached a video where the sound can be heard towards the end. The car has 230,000 km on it. 2.0 TDI 140 kw. Thank you for any advice IMG_0137.MP4
