So long story short, someone managed to cross thread one of the seat rail bolts while removing and reinstalling the seats. They then simply tapped a larger hole and used a larger bolt to fix the problem.

I would like (purely out of OCD) to go back the factory bolt. How do I make the hole the correct size again? And also, anyone know what the specifications are for the seat rail bolts on a VW Polo 6R?

There are two possibilities that come to mind straight away:

One use a helicoil to provide the size you want, which means drilling out to a larger size and fitting an insert - sounds like this has been done, but is it to the correct size?

Two is to remove the damaged nut and re-weld a new one into place...

I would live with the "new" bolt as is, then my next option would be to do the helicoil...
