Our 2015 Transit Tourneo Custom 2.2 has 48,000 miles and has started making a horrendous scraping/rattling noise on cold startup which sounds to me like it's coming from the timing chain area. It doesn't do it every single startup but when it does, if you blip the throttle the noise stops and doesn't return. Never does it from warm, only cold start.
Went to Bristol Street Cheltenham yesterday and showed them a video of the noise on my phone. They said as it's under warranty they wouldn't get approval to do any work until something actually fails !
So if the noise is timing chain related, they're basically saying it has to fail before they're willing to repair it which obviously will cost considerably more.
Has anyone else experienced similar noises on cold startup or experienced timing chain issues ?
