I have a 2010 2.2L MZRCD that Mazda have diagnosed as needing a new PCM (ECU). They want more than the car is worth. If i can source a second hand one what other parts need to be replaced as well?

Thanks. I did get on to Injectronics in Melbourne gave them the number of the unit and unfortunately they don't work on the PCM for the diesel 2010 mazda 3. So my only option is to replace PCM. just trying to find out if the PCM, key and ignition barrel are all that is required or is there other modules that will need replacing.

unsure,most cars they are vin linked
so you need to unlink old module before removing and then relink after install
or replace everything
