02 sensor headache

[jpilk99]

I bought an 03 X5 (3.0) about a month ago and the my check engine light is on. Before I bought it, I brought it to Autozone and they said it's an 02 sensor, Bank 2, Sensor 2.

I figured no big deal. Got a new one and now I'm under the vehicle and ...hating my life. Wire to the sensor is cut, but, no big deal. Previous owner probably doing what I would've done. I put a bunch of PB Blaster on it, gave it a few raps with a hammer & screwdriver at the base of it where it threads into exhaust. My 7/8" deep socket isn't deep enough, so I'm using my 02 sensor tool, but, the hex-bolt is stripping/stripped and I can't get a good bit on the sensor. Tried using a propane torch, but, didn't go too nuts; didn't want to overheat anything nearby.

Ofcourse there is no easy access to this sensor. It looks like I may have to take it to a shop and have them drop the exhaust. The bolts look obscenely rusted so I don't like chances of getting them off in my driveway.

Anyone ever wrestled such a beast? Bummin' me out.
Thanks,

Jay
