VW / Audi Variable Valve Timing Made Easy

2005-current VW/Audi 2.0T 1.8T direct injected engines

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
