So a rattle has appeared in the tailgate and I'm tipping it's something to do with the reverse camera I recently had fitted. I have 2 options. First being to take it back to installer which is a bit of a nuisance, or second is to quickly remedy the rattle myself.

I had a look at removing the trim last night but decided against it as the screws I removed didn't really loosen it up much and I couldn't find any instructions on here on how to do it. Does anyone have any pointers on removing the trim on the passat wagon, or does anyone know if it's pretty similar to this for a Golf?
