Nitrile (NBR) O-Ring Assortment Kit, Metric, ...: 
Universal Filter Strap Wrench for Oil, Fuel a...: Bosch 0928400804 is the fuel metering solenoid (inlet metering valve) that bolts to the high pressure pump: a silver body with two hole flange, a black coil housing with 2 pin plug and an O-ring sealed inlet. It is used on Bosch CP3 common rail pumps. This aftermarket valve has the same ports, mounting and coil connector as the original, so it fits where the old one came off.
The same part is also sold as Bosch 0928400803.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Function will not work
If a hydraulic function is dead but the pump and controls work, the solenoid valve or its coil is the usual suspect.
Drift or creep
A valve that does not seal lets cylinders creep. A new valve restores holding.
Burned coil
A coil that reads open or short on a meter needs replacing; check the connector for water first.
Fleet spares
Keep the common valves for your machines in stock to cut downtime.

Yes, it is a direct replacement for the Bosch 0928400804 with the same fitting.
There is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Measure the coil resistance with a multimeter and check for supply voltage at the plug with the circuit on. An open coil reads infinite.
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
No. It is an aftermarket solenoid valve made to replace the Bosch 0928400804. It is not made by the original manufacturer; the number only shows what it replaces.
