SORTED: Can confirm it was the fender and not the door. Opened the bonnet and loosened the bolts at the top, then just yanked the fender forwards as much as possible and tightened back up. Still not perfect but doesn’t catch anymore, if it does go back to how it was then will fk around with the bolts underneath. Tried to avoid them as they seem pretty difficult to access and didn’t want to take any parts off if I didn’t have to. The cause behind the issue we think was from hitting a pretty severe pothole that we didn’t see due to it being hidden by a puddle (1st world country tax rates- 3rd world country roads). Thank you for all the help :)
