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.
