Ultimate B7 A4 2.0T Information Thread

This is going to be a working list and I am simply compiling data into one place. As i continue to researching this i will update with more information as new information is given.

Hey Guys! I have been a long time behind the scenes reader on here and feel that it is my time to give back to the community. There is a lot of threads out there with useful information but they are spread all over the place. Its time for a centralized location.

Cam Follower: The Cam Follower in the 2.0T is a very well known part that fails. The normal recommended time frame to change them is 20k-25k miles but results differ depending on driving style. The reason the Cam Follower fails is easy- Metal on Metal friction. Some research stated that a slight oil starvation could also attribute to the failure.

The Fix: Check your Cam Follower frequently, if its starting to show signs of wear change it. The part cost roughly $40.00 depending on where you get it from. It would be a wise choice to keep one on hand.

Data Logging and understanding Vag-Com Measuring Blocks

Below are slides from a PDF on Ross-Tech’s Website. The slides will help you understand what each Measuring Block does. I would have put the slides on here but there was no easy way to do this as they are locked and not linkable. i will work on a solution to get the slides on this thread but this will work for now.
