Hi guys. Bought my 2010 3.0V6 Diesel XF last January. The dealer did the cambelt and water pump for me at 105K (they showed me evidence of old ones which looked same as the ones in the websites). The old cambelt seemed fine, but you never know. However, I'm getting a chain noise when starting the car from cold, which lasts for 2 seconds. My mechanic says it's the chain, but he's not a Jaguar specialist. Any ideas what this sound is? Does anyone else hear the same sound when starting the car? Thanks and regards
