Found and cured 2 minor (but very very irritating) rattles recently
With help from this forum one was located eventually just to the left of the front overhead light switch/sun roof control panel, could have swore that the rattle was coming from the passenger side rear door area but having no luck sourcing rattle and almost giving up was out driving and held hand up to headlining in area mentioned and to my delight the rattle stopped
So next day dropped very carefully the front headlining no more than a couple of inches, which was easier than I thought it would be, there was just 3 pop in and out plastic retaining clips holding liner in position
I could see a module which was hanging loose from its mounting and a cable supply which would have laid directly onto the headlining maybe causing the rattle, anyway using a bit of foam packing (sponge) I supported both cable and module which by the way operates the roller blind for pano roof then popped headliner back in place and yes that rattle has gone - Job duration 15 minutes only
So with one success decided to drop rear lining this time found a cable retaining clip shaped like a horseshoe which had a sticky pad at it's base it was laid in a tray that runs underneath the sun blind roller assembly I think this was rattling with vibration also at the same time as I removed the offending clip I checked the security of the blind roller housing and it did appear to click in place when handling it so could also have been cause of rattle
So popped rear lining back in place job done maybe 20 minutes spend on this one
Have ran the car quite a few miles now and hopefully that's it sorted it rattle free, overall it wasn't a great problem but as we all know a rattle really is very annoying and it's quite a nice feeling when they are silenced
I know I should have taken the car in to the dealers to get sorted I mean the cars not even a year old yet but it was one of those intermittent things almost certainly wouldn't have manifested had I taken it in and to be perfectly honest I would have instructed them to check out both rear doors as that is where I would have gambled the rattles came from it just shows you your ears can play tricks on you, so many thanks to the posts on this forum for advice in finding and curing rattles
