Noticed the A8 this morning making a very bad metallic racket up front and on the front drivers side of the engine. Gee, I wonder what is there...

Oh, it must be the infamous timing chain tensioner! LOVELY. At 138,000 miles I should’ve known!

I seem to recall changing two of these on my B5 A4 2.8 5v at one point.

I has a sad.
