Polo 6R 1.4 (86hk) Belt Noise Cold Start-Up? (Video)

Sooo… everytime i start my car up and its cold/or have not been driven for a while (hours) it makes some kind of noise, hard to describe exactly How it sounds but it definetly sounds like a belt noise that goes in full loop. Something like (tiki tiki tok tok, tiki tiki tok tok) and just repeats. The sound repeats every 2 seconds, to give you a hint of the speed it semester to spin/sound.
Goes faster as i rev more, and stops after 10-20 min.
I changed the fan belt, cuz it was pretty easy to do and needed changing anyways, so thats not it.
Does anyone have any similar experience? Shame i cant upload a video/sound..

Hi, are you sure that it is coming from the timing belt and not from the engine's valve tappets, this engine can and does become quite noisy as it grow older.
If it is definitely coming from inside the cam belt area, then maybe you should take it to a workshop and leave it there overnight so that they can hear this noise.

Well, im not a 100% sure, but it does come from that general area. And got a little bit louder when i took the plastic protection off on the belt area.
Here is a video, mainly to hear the sound, Will try and get a better video today when the car cools down and the sound returns.
Hope the link works,

It sounds like a belt, maybe, if you can make time, remove the auxiliary belt and then take another video if the noise is still there at a cold start.
Have you checked the health of your battery, if the battery is near the end of its useful life, after you take some stored energy out of it to start the car, the alternator will need to work hard to recharge it, and that will be create more than usual noise from both the alternator and its drive belt - and that heavy charging will end after a few minutes maybe.
