My 2005 s4 cab makes a heavy rattling sound at the moment of start up. It lasts only for a second or two then stops. Happens when engine is cold and hot, and not every time. This happens more often then not. DEALER SAID IT WAS THE HYDRAULIC TENSINERS FOR THEY NEED TIME TO BUILD UP PRESSURE TO TAKE THE SLACK OFF THE TIMING CHAIN. This I don't believe.. Could you please shed some light on this issue please and thankyou.
