BMW Repair: oxygen sensor, bmw 318ci, oxygen sensor

Question
hi rahim is it easy to change a oxygen sensor on a bmw 318ci !!  

Answer
It's not hard, you just need the right socket to remove it.  It's a socket that fits on the 02 sensor and it has a slit in it to allow the wires to hang through so you don't brake them.  If you spray some wd40 on it and let it sit for about 15 minutes then take it off it should come out.  Clean the wd40 off real good before you install the new one and connect the plug back.
