The title sorta sums this one up. I have the 'pull over safely urgent' issue message, ABS lights on. Code is 'brake circuit A' and sometimes 'brake circuit A and B'. Googling suggested the brake position sensor which I replaced today. I cleared the codes, but it came back up.

This issue is intermittent, pretty much 50/50 and once you start the car if it's off it stays off and vice-versa. I have a Volvo specific code reader and I cleared the codes with that, still came back. I had also replaced both front ABS wheel speed sensors out of an abundance of caution.

Also replaced the brake light switch sorta by accident.

What else could it be?

This is my 2002 V70 XC turbo inline 5.
