x70 is same part. Both P80 cars.
Brake Master pressure switch 96 850
I know it's the same part.
It's just not available
look below & see what I mean
There are sensors for the P2 platform but require a wiring hack due to different plug
Other option is the generic ATE sensor also requiring less of a hack
I've yet to have to replace one, but I do keep about 10 used known working ones in stock just because I refuse to throw away any sensor or relay as I'm parting cars out (everything goes into a labeled bin)
Mike , maybe the stored ones need to be soaking in fluid to keep that seal wet? I don't know but thinking once they have been used they may shrink. Mine failed at around 220K. Ran for a long time just topping up with a big nappy wrapped around it .. ......
They are all in ziplock bags for just this reason

Hello, is this still relevant? Looking to replace the sensor on my 850 with the plug ive linked below:
Otherwise maybe one off a p2 volvo would be more reliable
Anyone know if a P1 sensor works?
- Edited
i should be fine if @TL_V70 wants it, i have a smashed 850, but i haven't parted it yet, so hesitating on removing the pressure switch. Should have a P1 pressure switch with the plug if they use the same setup, otherwise i should have one off an 2014 xc90, not sure if its the same setup tho.
Ex850R Thinking i might just glue the hell out of the plug to reduce the leak, then when i go to replace just cut the plug and solder a p1 or p2 plug on. Even if i do end up replacing it with another 850 pressure switch, probably be good to replace the plug anyways considering the terminals have been soaking in corrosive brake fluid.
