Tried the grease through the door locks, and no joy so far still both doors rattle, and it is getting worse, big shame as it is spoiling such a nice drive.
There is another rubber bung just above the locks, so i pulled it back and sprayed a little inside there on the passenger door yesterday , see if that does anything, have to watch what i am doing aa i must be getting close to the door glass now.
The rattles seem to be coming from the top of the door panels inside, maybe halfway along or maybe closer to the door locks.
