The broken fog light (left side) came out from below quite nicely after removing the indicator, the fan shroud, and the trim pieces below the headlights to reach the remaining screw... yeah, there was only one holding it in place. The annoying part is that one of the attachments had broken off from the fog light AND from the bumper. Well, the bumper has to come off anyway when putting the fog lights back in. The left side head lamp's lower attachment was also broken, but the trim piece below the lamp seems to hold it in place well enough.
I thought that getting the right side fog light out would be as easy as the left side, so I went on to remove it too (instead of just covering it for the inspection). After an hour I had only managed to get it firmly stuck, and had to call it a day. Next day I took out a few screws holding the inner mudguard and the bumper itself on the right side, and got the bumper to give in just enough to push the fog light towards the radiator, where there was more space to slip it out from under the bumper. I bet it would've been easier to start by removing the bumper...
The heater matrix is now giving me an occasional misted windshield on startup. And the startup itself seems to be getting a bit lazy, which is probably the battery showing it's age.
