Timing Chain and Tensioner Replacement B7 2.0T

[EvolutionArmory]

thanks for the response.

is there a way to identify a worn timing chain or tensioner without any engine codes?

Yes, loud noise from the back of the head. You can also look at the cam phaser position with VCDS.

My car sounded pretty loud after my ride to work everyday. Sounded decent at start up, different after 40 minutes of driving.

Mine had the worn out cam phaser in my pic. The tensioner has plently of material left but it had a hairline crack.

You can visual inspect the tensioner and cam phaser just by taking the back cover off. You’ll need to replace the gasket and cover oil seals if you take it off. You’ll need a new HPFP and vacuum pump O ring too.

I recently borrowed a vcds cable from a friend. I would like to know the steps about inspecting the cam phaser position.

I know the basics about running a full scan and testing some electrical components.

To rotate the cams to align them to TDC, is it OK to rotate the intake cam using the cam wrench or do you need to rotate the crank with the 19mm socket? Like step 6 in the following link.

Rotating the crank is the best way to set the motor to TDC since you will be using the timing marks on the timing cover and crank pulley to confirm TDC.

The cam tool used in step 6 of the linked walkthrough is used to rotate the intake cam toward the exhaust cam to give slack to the timing chain when installing sprocket and chain as in steps 54 and 55 of this post. Alternatively, you can use vice grips on the intake cam, as Timmy from Astral Auto Repairs does, to rotate it for these steps.
