How to access the 02 sensors
These are the codes that I'm getting everytime I start the car: P2CAB, P2C3E, P2CA7
I ordered and received BMW part#: 11787558087 (emission system, emission components, rr oxygen sensor W/O 4.0L & TWIN POWER TURBO, upper, w/turbo) BMW part#: 11787558055 (LAMBDA PROBE) My question is how can I access and change these sensors in the car. I search for DIY for 2007 XI and couldn't find anything. Any help?

Rear sensors should be easy to get to. Front sensors especially on an xi require the passenger side motor mount or steering rack to be dropped depending on point of entry.
The sensors connect to engine block so you will need to pull the engine cover off.

Themyst, the codes I get is for the pre-cat O2 bank 2.
I just put the car on the rhino ramps. I'm going to remove the engine cover and under carriage cover as well. |

You could also cut the cable if you don't need to save it
