Weird ticking noise !! (Video added)

[aann]

Hi ,
I recently keep hearing weird ticking noise sometime in idle when the car is cold , also while cruising in 1500-2000 rpm .
I went to the dealer trying to figure out the issue , and every time i go there the noise disapears !!!
Had anyone been through this issue ? Anyone can help ?

Sounds like wastegate rattle to me, but it could be a million other things. The fact that it is there when it is cold and then gone when it is warm makes me think it's the wastegates. You need to leave the car with the dealer overnight so they can start it cold.

Maybe this noise can be a wastegate rattle or maybe something else !!
I dont have aftermarket downpipes ! but i do have akrapiviovc exhaust which apearently can cause this rattle !
I did some research in the forum , but i didnt find any solution for this rattle .
Is there anything that can be done to solve this problem ?

Have you checked to make sure the exhaust isn't what is rattling? Get under the car when it's cold and shake the system. I had that issue with the tips on my milltek system in a S6.

No the exhuast is set perfect and the noise is not related to the cold start or warm start , after i did alot of search on the car the rattle is clearly can be heard when driving the car in between the 1.2k - 2.5k rpm range .
The sound is like metal ticking noise thats that i hear when i drive in a narow closed places .

That noise is your clutch fly wheel it needs to be replaced I got mine replaced and the reason why I say this is cause that’s the noise I was wetting and the noise goes away when throttling over 2,500 rpm they will most likely need to drop your tranny

Do you have any video shows your noise ? How many miles you had on your car ?
Did you here that noise all the time ? Cause mine is not constant , somties it desappears !!

Update for the weird rattle that i had which apparently was a wastegate rattle .
i replaced the gasket between the midpipe and the downpipe , and also i replaced the gasket ring , no more rattle anymore
i have to say again that i had the stock downpipes , but when the akrapovic exhaust was installed the gasket should've been replaced too .
very happy that the rattle is gone , it was very annoying and i was embbarassed evrey time i was driving slow with low rpm's in the hood

Any chance you have a part number for these gaskets getting ready to replace exhaust and downpipes.

Sure my friend , i recommend replacing both the gasket and the ring , they are not expensive .
