Bad ABS module? Trifecta, speedo doesn't work, replaced sensor

[Bmwe5320023.0]

I'm wondering if this can be anything else, or if there's a way to test.

I've had this trifecta light for a few months.
I know my angle position sensor was bad, so I replaced and calibrated it. It helped somewhat.

Sometimes abs/dcs and speedo would work, and sometimes it wouldn't.
Now if I leave X5 parked overnight, the error clears itself.
When I start driving, it comes back on right away.
I removed the old sensor and cleaned it, but no luck.
Bought a new sensor from rockauto (Hella), and still no luck.
Clearing the error doesn't help.
I checked in INPA, and when driving, each wheel is showing speed, but not the left rear one.
I'm not sure what else to try other than replace ABS module.
