another question about 02 sensors

[kowalski]

as the headline says i just found out that there are 4 of them the 02 sensors.the question is are they (4)the same in size,functioning,becauze 1 of them was faulty and only 1 is replaced,so next time when i have to replace the others i need to know which one is where.Or do all 4 of them fit anywhere where they should be?

are the 2 of them on the front cats mounted near the firewall and the other 2 located where?

the other 3 i won't buy them from mb feels like i get jipped. :mad:

They are all different. Mainly in wire length.

Pretty hard to get too, but 100x easier if you hav the car on a lift.

hey buddy i wan't to ask u about the o2 sensors? when i have to change the others in the next future i won't use the crappy stealership to put them on my car instead i'm gonna use another garage to put them on. the question is do i need to hook the car up tho the computer and edit the faulty codes or will my car relearn by it self when i drive the car,so i don't have the wrong codes:confused:
