So I've got this a4 here that had a ticking for a while, it goes away as you drive away so i haven't been as worried about it. But the other sound i got just yesterday. The "thumping" sound. Anyone have any idea what that might be? It sounds like its coming from the front/tb area but it could be sludge related also. Tb was changed about 25k miles ago. Anyone experience this sound before? I feel like im gonna go crazy, sounds horrible and i dont know what it is![headbang]

I think that may be the cam chain tensioner failing. Here's a video with a car that makes a similar sound to yours and was fixed with a new CCT:

But before you go after a new CCT, you should check out your oil pressure to see if sludge is the issue.

I always thought it was the cct but a friend of mine has the same sound as your video did and it sounds alot different then mine. I driven the car only down the street after i got that loud thumping sound and it sounds like something got extremly noise, sounds like something is about to fall off while going on a bump/bad road. Also i revved to around 2k rpm and it sounds like something is bouncing around.
