Heat on an O2 sensor?

Use a torch to heat the bung the o2 sensor threads into if you are having difficulty removing it....I.E. it is seized.....don't be a jerk & put visegrips on it...use a 22mm wrench or the appropriate tool if you want to avoid a mechanic....anyways don't drive a bmw if you cannot afford to maintain it in the 1st place....buy a kia
