I haven’t had the time to work on the car the last few days.

Still no brake lights & shifter still won’t move from Park unless I use screwdriver in the release hole.
I also cleaned them ground beside the battery & removed the 3 ground wires & cleaned terminal on left side near the fuse block. All were good.
The BAS/ESP light went out when I used the lock to lock method to reset steering angle sensor.
I have run an OBDII scan twice. Because I discon next the battery each time I stop for the day, I was not getting any codes, pending or otherwise. The 2nd scan I run, after the car had been idling about 10 minutes, the engine idled down & cut off. Restarted immediately and a couple minutes later, stalled again. It didn’t immediately restart. When it finally started again, the scan tool then showed a code PO 151, o2 sensor Bank 2.
I bought a brake light switch from Carquest, but haven’t put that in yet. Also got the blue check valve for the air injection, but haven’t put that in yet either...
Not sure if I will have time to get back to work on the XF this week, between my job & the weather & repairs on my house.
