Default ABS Sensor faulty (VIDA) which one?

Hello,

So I've had the ABS-light on in my dashboard for some time, and I recently scanned it with my VIDA/DICE which gave me these errors:

(Images too big to attach them here)

Now, I'm not sure which side the faulty one is but I've noticed when I turn the wheels to left the light disappears and turn to the right it turns on.
Is there a way to know which one is faulty for sure? Or should I just replace them both?

I guess 2x of these would be good
(they work for both sides, there is no right/left correct?) https://www.bildelaronline24.se/stark/7856882 Part No: 30854299

Is there any guide on how to change these sensors, I could maybe check if the connector is loose before ordering new ones. I believe it's easy, just removing the wheel and unclip the wire and unplug it. But I'm not sure where the wire is plugged in

I got this when I double clicked the fault code:

I also noticed that it's harder to get the light turned on now. Before it used to be as soon as I turned the wheel to right it would light up. Now it's only if I'm at a higher speed and do a sharp right turn. Would this indicate that it might be the sensor cable being loose? Or could it still be the reluctor ring

its quite rare for sensors to fail check the rings it only takes a small split or excessive rust to create a fault

Alright, yeah I hoped for the sensor to be faulty. Because the rings are pretty hard to access and replace from what I know. Do you have any easy guide to do this the best way?

I'd blame the sensor. Reluctor rings can break, I'm told, but i've never seen one. A decent diagnostic tool will tell you which wheel is reporting the fault. I didn't have a code reader, so i asked my local garage to read the codes for me, cost me 20 but ensured i got the right one.

The main issue is the sensors are electronic and sensitive, and their position is unsprung. That means they get the full force of all the jolts, jarrs and all the weather, grit, salt, spray. These sensors really suffer. Reluctor rings are just dumb bits of metal.

You'll find out when you come to remove the bolts for it. They'll be rusted to buggery. The big problem will be getting them out, getting them in again will be practically impossible, you'll have to buy new ones almost certainly.

reluctor ring fail all the time iv had my v70 7 years and iv replaced 3 broken rings in the time iv had it check them it cost nothing to look at them rust on the rings can also wear out sensors if it gets bad enough if you do end up needing sensors shop around. last sensor i bought was 18.volvo wanted 70 .
