I'll try and get a video of it and then figure out how to post a link on here. It worries me that you say the d5 are generally quiet engines. I need to get my hands on another XC90 D5 to compare. Failing that, I have a local specialist who seem to be pretty good but I'd like to go with a general idea of whether I have an issue or I'm just going bonkers.
