That transistor controls the auxiliary coolant pump. Your aux pump is probably seized and has destroyed this transistor.
You could replace the transistor (BD435) and its driver (BC517) after you replace the pump. Also install a fuse at the pump so this doesn't happen in the future.

Aux water pump died and disconnected but not soon enough to save CCU.
Thanks for info on parts .
