O2 Sensor Replacement Post Cat

Here's how I got the job done. Vehicle - 08' E70 X5 3.0si. Used the tools pictured and Bosch sensors 16413, 16414. Got both of them for $150.00. Purchased them on eBay. Anyways, I was able to move around rather easily with X on Rhino Ramps. First I removed the "UNDERFLOOR COATING CENTER" the metal plate right under the trans. Held in place by 8 7mm? bolts I used a small 5/16 socket. After you pull the plate off you will see the O2 connections and now you can access the sensors. Now time to remove the sensors. The first one is the easiest. I used a small crescent wrench to remove it. If you need more power put in a small pipe to help. Disconnect the connector with a small flat blade screw driver make sure not to crack anything. Remove the sensor. Second one is a bit tricky. You need a low profile O2 socket to remove. This one sits vertical. You can get to it by sticking your hand under and over from the right exhaust. The sensors have a aluminum? cover on them so the O2 socket wont fit with it on. You need to carefully pull it up to give the socket enough clearance to fit. You only need to do this to the 16413 sensor. Manually turn the sensors to remove them and move the tail ends around to let you rotate them. After that install new sensors in reverse order. Nothing to it. Also just a note: you can not install the wrong sensor in the connectors as the designated one will only fit in, but you can install on wrong exhaust, so pay attention. 16414 far left towards passenger 61413 to the right towards driver.

[QUOTE=gregg3gs;1072289]


I was able to pull off the job with out the wife's hands. Wasn't as bad as I thought. My E53 was a bigger PITA to pull off. I think I took all day on the post cat for my E53. So I replaced both sensors with Bosch part number 16413 16414. I removed the protective plate covering the trans and that gave me access to the O2 sensors and connections. The first one I was able to remove with a small crescent wrench. Second one was more of a pain. Rented a O2 removal tool from local autoparts store. I used the short socket as that was exactly what I need. It took about 2 hours give or take. I reset the code and now well see what happens. Before erasing code notice I also had a P0162 along with the P0161 which I think is related to the P0161. Now someone before mentioned checking the fuses for the O2 sensors. Where the hell would those be ? I hope this solved the problem. Anybody know if the E70 has a fuse or relay for the O2 sensors?

Well there not basketball player hands, but far from small and I was still able to get the job done. There's enough room under there unless you have Andre the giant hands. :-l. I guess if you have very small hands you can finish faster? I think it doesn't matter in this case. It's very doable.
