Yeah true, I've read a bunch of stuff here already about DV's and I found one guy's website... forgot his name... who showed how to do it from the top. But then I got confused because people including yourself are saying you have to do it from the bottom. Another thing is that I can't even find it when I look under the hood. From reading that guy's website it looked like it was near the ECU, towards the back and to the right of the engine. Then I started looking at VW drawings of everything that was under the hood and it looked like the DV was on the other side near the air filter.
