My beetle has been making this ticking noise since 2014 now and not sure if my cam chain tensioner needs replacing or not. Here is a youtube video somebody else posted of the ticking sound but mine is not as loud. Any ideas folks?

Do, you have VCDS? You can do a output test and confirm, if the chain is stretched or I think, if the sensor, indicates if the tensioner is failing or malfunctioning. Let us know, if you have a VW type scan tool; like VCDS and we can discuss, how to do the testing/output test procedure. Thanks.

thanks for replying. Yes I do have VCDS VAGCOM but not too familiar on how to use it. Do you have the steps and or procedure to run the output test and check if the chain has stretched? or the tensioner is failing?

Hey, you would be looking into the measuring blocks:


For the 1.8T; one would need to see, which ones show the right info:


Looking online; one website, discusses the readings and what you would typically see, depending on the milage and problems, you might be having.


Following info found somewhere on the russian net as official manuals say nothing for first and second stage of EA888 ...

How to diagnose a chain stretching?

Connect VCDS --->

go to Block - 1 (engine)

---> measured group

---> 93 group

---> Phase Position.

What is the angle of misalignment of shafts critical for us? 0 - 2 degrees - a value characteristic of the new machines, or machines with the new circuit; 2 - 4 degrees - the recommended chain replacement value at which you can hear a clear metallic ringing of the left side of the engine))) 4 - 6 degrees - Urgent replacement or dumb luck.

I haven't done this yet with VCDS on my 1.8T; check out the measuring blocks and any values, you see and hopefully, you can see if you need to replace the chain/tensioner. Let us know, what you find out and we can go from there. Thanks.

I'll try to hookup the vcds sometime over the holidays and see what I can figure out. As of now it's clear as mud. I'll see what I can figure out.

Anybody that has done this job before on the 1.8t know what is a good kit to buy? not too expensive or cheap just kinda the middle of the line? Does the tensioner part number have to be specific to your engine # IE....AWV Or something like that?
