Tell him to go ahead and do it, and that you will write them a check for it, but there is "no guarantee the check will clear". When they find the correct part that fixes the problem, tell them thats the part you will cash pay for.

I share your frustration in a company that cant more accurately diagnose a system that has been in place on this model line 7+ years now, and they only way they know how is to start shotgunning the problem with new parts, at your expense.

Without researching it, I'm not sure what each of the codes stand for, but I would check the brake fluid level in the master cylinder, all the O2 sensor connections, and check the ABS sensors to make sure they are in properly in place and their connections are tight. Good luck and let us know how this all ends up.
