Timing chain tensioners...

Do these values essentially tell you how far the chains have "stretched", or guides have worn causing a slight change in the factory parameters?

I use my VCDS for my Audi B 8.5 2.0 to monitor this very value, as they are known for a tensioner failure. Mine has the updated tensioner, however they only have so much adjustment available to offset chain stretch or guide wear before you need to replace the guides and chains. Audi calls it "adaptation" values.

I'm thinking this applies here too.

Thanks
