I have a 2004 range rover built with bmw engine 03-04 are the only year. I got a engine check soon light and it read p1173. Which is the pre-car 02 sensor. Bank 2. I changed it but still went on. Do I need to change the post-cat o2 sensors as well. Find out on friday what the computer will read.
have the same problem?
