engine rattling on startup

whiteoni · 11-08-2007, 07:59 PM

Newbie who just purchased a 2007 S4 sedan (manual) this summer and continue to experience engine rattling at startup. I brought it back to the dealer and they've informed me that it's common on S4s during cold startups, but I'm noticing the rattling on warm startups as well. Anyone else experiencing this? Should I be concerned?

delayed oil supply to the tensioner arm which causes it to rattle against the casing very briefly from start up.This is regarded as acceptable as there is no technical defect.

Very slight but didn't cause me concern.

How ya liking your S4 whiteoni ?
