Why did the sump plug o-ring have to be changed on the Corsa?

My mam's 2007 Opel Corsa came back from a service with the garage saying it had to replace the 'sump plug o-ring' and I am wondering what could have caused this?

Hi Karl,

This is nothing to worry about. It's good practice on a lot of cars to replace the sump plug seal whenever the sump plug is opened to drain the oil. It prevents slow oil leaks.

I assume your mam wasn't charged very much for this? It's an inexpensive part and there's no extra work involved if the sump plug has already been taken out.
