If it was water it should not have caused internal engine damage unless it stuck a couple of injectors open and it was driven hard enough to melt a piston or two. The other possibility is stuck open and hydo locked a cylinder, and the last is it wasn't water but something corrosive and it rusted up/stuck the rings. You need to ask the dealer why they think they have internal damage.
Also a comment on the WIF sensor. The only way it can work is if the liquid is conductive. So if you have water from condensation it likely does not have enough mineral content to turn on the light. I guess I need to try it, pour tap water in the canister and then try distilled water. It would be interesting to see which one turns on the light.
