    Slack in the chain possibly, sure it uses hydraulic tensioner, so its possible this has slowed down on startup, as it takes the slack out of the chain upon start, I had it on my S4 B6 avant aswell, but everyone I asked said it was normal mate, wouldnt worry to much until, it is doing it whilst running aswell.

    Can be a few things, but read below for a bit of help

    S4 have always been like this, there is a brief delay in oil pressure to the tensioners after a stationary period

    A8 tech and that guy Crasher have been fixing VAG cars for a lot of years and know what they are talking about

    I know that name Crasher from somewhere.

    Can you post in here his info as requires signing up to see that info.

    Yeah as I thought, tensioner for chain, never caused any issues on my S4 in 2 years of use, made the tiny bit of noise rattle for split seconds but worked perfectly
