L405 Vogue rattle / knock from B pillar / rear door offside.

And it's annoying me.

It seems to be when the car flexes over uneven terrain. It is almost as though the back door needs adjusting. It can actually chatter a bit over very uneven road surfaces.

It's booked in to the dealership in 10 days but does anyone know if there is anything I can try myself? It's quite irritating.

There are two plastic rails (body coloured trim) that run along the roof that feel like they are stuck on with double sided tape. Could one of those have come loose? Way to check is press down / tap on them and see if one has lifted. Just a thought as I had this issue once.

Is this internal or external?

External. Body coloured strips that run along the roof either side of the sunroof. Will try to take photo over the weekend.

It could well be the door but still worth checking out.
