07 s80 v8 awd
 

Abs+dstc+brake message came on with the message brake failure stop safely.

Had no abs brakes. Roads have been extremely snowy and as this beast was munching through it with revs between 3 to 4.5k it was going and going and then as I hit the brakes quick it came on. At restart all messages and errors went away. I feel like the timing of me braking and the abs kicking in with dstc caused the error, like the timing of me braking with those systems caused the problem. At restart abs system, dstc, and braking all worked fine.

Hooking my scanner to it pulled p0304 cylinder 7 misfire which I know is probably wrong?

Finally does anyone know if the abs module is covered under a cpo Volvo?

It has 83k miles on it, thanks for any insight!
