The A3 141 code cleared out OK -I reseated the sensor connector and
packed it with dielectric silicone.
Then I found an A2 436 code "Max compensation rear O2 sensor"

How are these two codes related? Everything has been quiet with OBD codes
after finding the switched vacuum lines on the EGR controller.

Upon resetting the OBD 436 code, It sounded like the brake booster
released pressure with a noticable hiss.
