Finally decided to fix the p1710 code on my 5eat, ordered the sensor and filter:

Decided to pull the valve body and check if a generic hall effect sensor would fit, the one I ordered is too long for this location. So everything is covered for now, waiting on delivery.
To pull the valve body, had to take out all the black bolts and the two longer bolts under the filter. Hoping I remember that for the reassembly.
