In this excerpt from Autologic's NCTS 2018 training event, Auotlogic Technical Support Specialist Chris Martino covers the design and function of variable camshaft timing on Audi and VW 2.0L engines. This video is part 1. In part 2, diagnosing will be covered.
Sample codes include P0021, P0022, P0016, P000A, P0011, P0012
If you ever wondered how VW/Audi made variable cam timing work? Ever had a trouble code for cam timing and didn’t know where to start? How does VVT work in general? How can I test VVT to see if it is working? What is inside a cam phaser? What is a central (4/3) valve? What is a bearing bridge? What do I do when output tests fail?
