This is our DIY showing how to replace your Crank Pulley on an Audi 3.0T. On a C7, you may not have to use service position to do this job if you have the right tools, but it does make the job a lot easier. If you want to learn how to put your car into service position, look in the links below for our video on it.

I replaced my 187mm crank pulley with a Velocity AP 205mm oversized crank pulley to achieve a Dual Pulley ratio and finally go dual pulley on my car.

Let me know what you think of the video in the comments!
