Thanks to "yoogene83" for this helpful DIY. However, I am still confused over step #5. Can anyone please elborate or DUMB IT DOWN for me, as I am in the process of replacing my timing belt on 2002 Audi A4 1.8t.

5. This step is the very critical. Carefully align the 2 timing marks (one on the cam sprocket, the other on the edge of the valve cove) by turning the engine by hand, clockwise, using the 19mm bolt on the crank (where you removed the dampner pulley from earlier). While you have the belt off, you must make sure that these marks remain perfectly aligned. DO NOT use the top cam to turn the engine; always turn at the crank when the tbelt is installed!

Another tip is to mark the belt where the mark is and then mark where the crank pulley mark is at. This way you can count the teeth (if need be) if you aren't sure your marks are lined up with the new belt.

Also make your own mark the lower toothed sprocket on the crank, just for your
own comfort of knowing that the sprocket remained in the same position throughout the install. I scratched an arrow on the sprocket; as you can see in the picture that the mark aligns with the tip of that protrusion in the metal above it. So after you have marked the top cam and the bottom crank continue to the next step you will also notice that the top cam is very hard to turn by hand so it most likely won't move but marks are critical!
