Not dissing CMS at all but the header tank failure is well known fault on both 996 and Boxsters
They knew that but I appreciated their thinking of starting at the start with the cheapest potential issue (expansion tank cap) and then working from there.
There was no apparent leak from the expansion tank, it was a tiny hairline crack that only opened up with pressure / heat
I'd have been a bit hacked off if they had just assumed it was the expansion tank and it had turned out to be something cheaper to remedy
