So I think you might need more posts to post a link, so entertain us and respond in separated posts to help your initial count:
Did it start after an oil change?
Is the oil the full synthetic 5/w40?
Is the oil filter OEM manufactured and good quality?
One in a million, but wrong filter might prevent pressure buildup speed. Same with oil. If not using it, you might switch to the VW approved Castrol. Different oil manufactures have slightly different grade weights and viscosity and this could be an issue here.
Someone at Vortex had this and decided to do the chains and everything (generally agreed to be a source). The fly wheel was also inspected and a new flywheel ordered, but there was zero difference in the new and old flywheel play. After chains, guides, and tensioner the thing still sounded the same, but at a slightly reduced volume (in other words not worth it to me). VW points to the source being initial low oil pressure at start up leaving the valves with a rattle until pressure is achieved, I partially believe this as well as clearances at cold are greater and naturally will result in more noise / clatter...had an 88' Jetta 16v that ticked like a diesel until all the sudden it was warm (took four minutes) and it would stop...it did this day one and at 300k...sometimes worse and sometimes not so much?????? who knows.
