What is the year and engine of it?

Are you trying to replace the sensor(s)?

Customer: replied 7 months ago.
car is XC70 D5 2006 105000 miles. Fault codes are ECM 28E0, ECM 44B0 occasionally ECM18B0 and ECM 135F. High fuel consumption and sometimes hesitates in normal driving.
Unless advised otherwise like to replace O2 sensor however it would appear to be very inaccessible

I am so sorry, I don't seem to have anything on that one, but wait I'm sure there is another expert who knows. I will opt out and open it back up. Please DON’T REPLY to this post as that will lock the question back to me, someone should be along shortly, I’m sure, thanks and sorry I wasn’t able to help with it.
