In July 2015, I had my Golf repaired due to stretched timing chain. It was a VW "pro rata" repair, meaning they covered 60% labour, and 100% of the parts.

Now, exactly two years and 25000km, the EML came on, and the code "Incorrect Correlation P0016/628" error apparently indicates timing chain stretch.

I'm interested in the general opinion on this. I'm thinking a timing chain should last considerably longer than two years/25k ?
