VW / Audi Variable Valve Timing Testing & Diagnosing The Best Methods

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 diagnosing faults with variable camshaft timing on Audi and VW 2.0L engines.

The engine in the class was a CCTA full chain drive engine. The earlier timing belt/rear chain engines function the same, just the phaser is in the rear and the solenoid is a conventional design.
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?

This video shows you how to test this system and diagnose faults.
