I can't remember if 2000 C70 was M4.3 or what, but start here. https://www.matthewsvolvosite.com/volvo ... 5-to-1998/
Help keep MVS on the web -> click sponsors' links here on MVS when you buy from them.

Also -> Amazon link. Click that when you go to buy something on Amazon and MVS gets a cut!

It is ME7 but that is the ECM only. He wants all the codes. There are 16 control modules on the 2000 C70.

For ECM codes all P0xxdx codes are SAE standard so they are preserved across makes.

The internet is a good resource for identifying most fault codes. You do have to sort the meaningless results from the good information.
