Has anyone replaced the original DPF pressure sensor (C2S44658 £743.36 Inc Vat)
with the one for the S-Type (C2C39730 - cheap) + hoses ?

Various parts suppliers list the C2C39730 as compatible

 

I didn't get to find out.
Badly installed short pipe on the DPF had pushed the hose into a sharp bit of metal (heat shield ??) and it had cut through the hose.
Turned the pipe and refitted the existing hose.
No more Engine Management Light and no more error codes
