I need some help...

I have a water damaged MJD 6O3.S7 ecu from an Opel Corsa D.

Cannot find a replacement ecu anywhere :( So my questions :

1. Is it possible to replace with 6O3.S3 or other version?

2. If I find a compatible ECU - is it self-coding if I make it virgin, or do I have to have access to dealer tools to syncronize it?

many thanks
/Lars

Thanks, but what is "same" ECU. What numbers must match?

See this for example. It is an MJD6O3.S3, but has same HW number.

So another ecu with HW03A will work even if the other numbers doesn't match?

BTW, GiannoNOS - Was it from you i bought a used MPPS many years ago? :)
