Hi new to the polos I got a 6n2 and it has a bit of a hole in the boot I filled it in with filler will this let it pass mot

depends where it is and they can see it

should be welded if within 30cm of suspension points etc ...although if youve done a awesome invisible job then yeah maybe it will go unoticed

Unusual to have a whole in the boot on a 6n2.
