E93 335i N54

I have a E93 335i, the previous owner fitted a down pipe to it but didn’t plug in any O2 sensors. Because of this the car is rubbish on fuel on is running extremely rich. I have brought the front sensors, I put the car on a lift today but the front sensors look very difficult to do. I have read many threads saying unbolt the steering rack and move it out the way but that only applies to LHD cars as the RHD cars have the steering column in that area. Any tips on how to do this job without removing a lot of things?
