Has anyone else had them?

I've had a knocking on bumpy roads for some time and noticed one of mine has been loose when i removed the towbar loom a while since.

I've tried to tuck mine back into place several times tonight, only to end up breaking the clips.

So i removed the whole vent and packed it with two pieces of large foam, hopefully this has cured the constant banging on uneven and sharp bumps.

The other question i have, does anyone think that i may have caused myself even more problems?

Given that i've taken one of the flap assemblies out and used some high density foam to fill the gap between the inner wing and the hole?

Well it wasn't the boot vent:O

Oh well, at least its doesn't fall through now lol.
