Thanks everyone for your replies. there was no fans running previously about 10 hours before it happened as I was in the garage & didnt hear or smell anything. the fire started around 8am. @paddock suggestion of posting on swedespeed.com, I cant as i have been waiting for my account to be approved by an Administrator, for over a month now :(.
I will try Volvo Aust to see if any recalls in effect for the VIN number but dont hold out much hope of a result. If anyone is after an XC60 for spares, sans the engine obviously, let me know. All panels & interior mint, located in Sydney.
