This is the Bosch 0445110558, a new common-rail fuel injector, not a rebuild, for the Deutz TCD 3.6 L4, the 3.6L four-cylinder. It is the injector Deutz sells as 04123831. It comes with the seal ring. The engine takes four.

Hard starting, a miss, rough idle, white or black smoke, fuel in the oil or a cylinder balance fault that follows the injector all point at a worn common-rail injector. Dirty fuel and water are what usually kill them, so fit new fuel filters and check the tank before the new injectors go in. The smaller Deutz 2.9L four-cylinder engines use different injectors (Bosch 0445110560 and 0445110561), and they do not swap with this one.
