Do yourself a favor, and start just trying to shake stuff , anywhere near the exhaust manifold, anything, make sure its not just something loose. Would be nice if thats all it was. Start with a simple shaking test, and see if you find anything loose, and if you do, see what you gotta do to fix it, and then go from there. Let us know what you find.

iono about your knock noise... but my i think i have the same problem as your. but i got to work. its my egr valvue pipe that came out from the egr to the egr cooler. that one like a h shape thingy thing. i got air leak right there on the two bolt that tight the egr valvue pipe to the egr cooling tho. hope the same for you. how do i know it. i shut my engine till the motor is cold. n i start at cold n put my hand around it to find out if i got any air leak. and i found out that there is a air leak. and now i got turbo on my mk2 so i decide to block my egr valvue so now i dont have egr no more. so hope this work for you alright. let me know how u get to work alright.
