Hi all, wonder if you could run a collective ear over this video i shot this morning. A4 tdi noisey cold start - YouTube It only does it when cold 1*c or less, its a strange noise, just wondering if anyone has similar experience. It starts with a rattle, then a metallic hollow sound (like draining the dregs of a milkshake through a straw) sometimes a little longer than this one, then its gone. Its done it before and after fresh oil and filter service. My first thought was something to do with the starter motor not disconnecting, but why only when cold weather?
