Only two on your E46.
How many oxygen sensors (lambda)?
Hey, I heard that e46 had 4 lambdas so I was looking for them and found two on the exhaust cat. I couldn't really find nothing else.

I'm seeing a lot of corrosion that may prohibit that O2 Sensor from being removed and I'm also seeing a crack as well.What do you think about these?
Well, it shouldn't be cracked so having it fixed is a good idea. Is it the cause of the smoke? I can't say but if the smoke smells like burning coolant, you could have a bad head gasket.... should I get this welded asap? Could this be the thing causing the mpg?
