Cosra D 1.3 cdti Can I use MJD 602 ECU to replace MJD603

Hi All

Is there anyway an MJD602 ECU can be used to replace an MJD603 ?

The MJD602 is from a combo van which is is the same year as the corsa

Thanks

Try it.
Can you program it?

Hi

I programmed the 602 with the 603 files which was ok

The only problem when I put the ECU into the car the fuel pump dosnt work and the injectors are clicking when the ignition is turned on without the engine turning over,

Is it worth leaving the original 602 file in the ecu and change the eeprom file only ?
