I don't know where mine is. I installed new heated seats during the summer and when I tried to use them a week ago, they didn't work. I found out that usually fuses go wrong, so I tried to change them. But I couldn't find the fusebox in the boot.
Also, I spoke to someone else with a 159 and his car has the fuse box. He doesn't have heated or electric seats, nor does he have a built in amplifier, but he has the fusebox.
So, the fuses in the boot are for the seats and that amplifier, and even if he doesn't have those options on his car, he has the fusebox. I don't.
As far as I know, it has not been removed. I see no reason to take it out. I just want to know if there are any other 159s without the fusebox in the trunk.
