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?
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.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.
Do you know how to start the test using Measuring blocks section? it wouldn't do anything for me and i couldn't find info in google either.So, it looks like you passed the "test"; I'm wondering, if there is a way, to read the actual degrees, as noted in other engines, like the VR6 noted above. I would think, there would be a test and then, degree correlation info, so you could know, what the actual chain/tensioner wear is?
The cheat I linked to: https://www.ross-tech.com/vag-com/m_blocks/090-098.html
Has some of the blocks with the test and then, some without it. I've noticed, when working with VCDS; sometimes, you research the blocks and then, you find other blocks, by going up or down, then I have found things that way. If I have some time, I could try; on my 02 Turbo S AWP 1.8T with the variable valve timing and see, what I find.
