What were the codes before you replaced the regulator and what are the codes now?

I can only assume that you changed the pressure regulator because of prior codes.

Code C1000 requires that you replace the ESP Control Module which is housed in the underhood fuse/relay box.

Remove the covers to the box, pull up the module and copy the number down, 163 545 xx xx, and buy a used one and install.

Then clear all codes and see which ones return.

No, if it is used.
