Huraaahhh, it is off after some tugging and "gentle" force. It is those clips from previous post. I only need three clips and three of the rubber housing that fit in the door holes.
Make sure you fit all new clips to the moulding, and all new caps inserted into the door, no matter how good the old ones look!
Tip, To fit everything properly, wash the rubber caps in warm soapy water, to get rid of release agent used in manufacture, (this will allow the cap to grip the edge of the hole better) let them dry, and push them home into the holes on the door...
Then fit the new white clips to the door moulding, once done, apply a tiny amount of washing up liquid to your finger tips, and very lightly coat the end of the white clips, at the point that they push into the rubber caps... this will stop white clips tearing the caps, or pushing them through to the inside of the door, which is a real pain!
To fix the moulding to the door, simply push it into position, any clips that haven't seated properly, can be sorted with a sharp slap with the palm of your hand...
