thanks for your response.
Having been underneath (and got a bit dirty) I know that the connector shown on the page you sent does not exist on the WG diesel. The sensor/cable comes as an assembly, see: -
I do know that the WG series like mine were made in Austria, and my guess is that the sensor/cable assembly is cheaper to produce than with an intermediate connector, and probably cheaper to assemble in production. Never mind the poor guy who has to replace it - he can sort out his own salvation!
All I need to do now is suss out how the connection is made to the CAB.
I guess I will have a better idea on that when I receive the replacement part.
