I have a 2003 LR Disco with 117,000 miles on it. I am not a mechanic and have been using an independent mechanic in town for years on all my cars. He has recently retired (closed his shop) and now I am in the market to find a new one.

About 4 days ago my SE light came on. I was finally able to get to a shop to run the code(s). This is what came up.

P0139

P1171
P1415

The car has not been giving me problems at all the whole 3 years I have had it and I have been regularly servicing it.

My guess is that I need to have all 4 O2 sensors replaced to start with and then I am open to suggestions as to what to look for next. It is not my daily driver so I will be doing this is stages.

Last question, any idea of what it should cost to replace the for O2 sensors by an honest mechanic
