Smells like monkeys bollocks to me - do not accept it.
It's been overtightened there and then or it would have leaked sooner.
The pan is ally and therefore weak when it comes to overtightening. There's virtually no chance it would crack when being untightened imo, and i've never heard of that happening in all my mechanical years. Tell them it wasn't leaking when it was brought in, they have worked on it and it now leaks. Unless they give you a new pan, installed, you will be getting a report done from a quailified mechanical engineer...
I've seen one on here crack in that same place before, think it was Dembo. That was tightening up.

If they value customer satisfaction - you should not pay.
Be pleasant. Be factual. Be firm.
Talk about customer experience / customer satisfaction. Talk about word of mouth & reputation.
Don't pay a penny.
at the extended time in the Jazz

Dave, I can only imagine a hairline crack had developed from when it was overtightened, and when it's been tightened again it's really gone. But there's very little chance that it will crack of it's own accord from unbolting (as you know)
There is only a couple of psi pressure in the sump so it's not going to force out unless there's a leak path.

No monkeys bollocks, because the same thing happened to me. And yes it was my fault entirely. I went to change the oil and it was very tight, but got it undone. Then put the bolt back in, filled up with oil and went for a run and had a small drip. I actually went and bought a new bolt, thinking it was that, but on closer inspection I realised there was a small crack from the bolt hole in the sump.
Definitely my fault for overtightening it the previous time, and no it didn't leak. And as for noticing it was tight and not removing - what are you going to do? Never change the oil again?

).So, the dealer could actually be right, and theres a possibility, however remote, that the previous oil change could've been the cause??
true. If he was using a bi directional ratchet spanner the wrong way and have it a good tug!

Cold plug screwed into a warm sump, same as spark plugs is never good
I had something similar years ago but the garage phoned me to say it was tight and wanted my OK to kep trying as long as I accepted any resulting damage, they warmed the sump and cooled the plug and it came out easy

Thermal coefficient of expansion for ally is quite a bit more than for stainless IIRC. So Ally expands at a higher rate than steel for a given temp. So a hot sump should mean the plug comes out a little easier...
