Very helpful Dave, should the need ever arise I will refer back to this.
When I needed to renew the FOS sensor I had to destroy it. It came out in several pieces. The replacement was a Bosch ( 0265001231 ) obtained through my local Bosch agent, rather than my Volvo dealership. £54.58. For items such as that, ( eg lambda sensor, ) if I can find a Bosch part number I usually check with both the Volvo and Bosch dealers.
For the record, whilst tracing the fault I noted the resistance of the “good” sensor in the FNS as 1,080 ohms. The resistance of the new Bosch sensor was 1,093 ohms. I believe that the spec. 900 ohms to (not sure).
