Mondeo MK3 TDCi Delphi injectors have to be coded to your car for them to operate. The injector should be supplied with this code, there is a 16 digit (Alpha/Numerical) C2i injector code on the label on the injector.
If your injectors develop a fault and you decide to have them reconditioned you will not have to re-code them back to your car as long as the correct injector is placed back into the same cylinder it was taken out from and the injector has not been issued with a new code.
On the injector label will be a code starting with “EJDR” e.g. EJDR00301Z. This code refers to the type of injector in your car, its basically a “delphi part number” for the injector that many companies work from.
If you replace your injector you will need to match up the EJDR number.
The Injectors with the number EJDR00101Z and EJDR00301Z are interchangeable. If you swap these injectors in your engine you need to remember that the 101Z injector has a rubber O-ring and the 301Z is fitted without one.
Below is a list of the different types of injectors fitted to which types of Mondeo MK3’s.
