There is a volvo special tool to unlock the connector block , the purpose is security so that a thief cant easily take it out and substitute it for a doctored unit with no immobilier and drive your car away ...

Hi thanks for your fast response this is going to be interesting i let you know how it goes the reason i am taking it out is that the coolant temperature gauge goes straight up to maximum as soon as you turn the ignition on we have replaced the sensor but its no different i wanted to test the wiring back at the ecu because it then eliminates a short, are there any common problems with them? Regards PhillW

Idealy you want to read off the coolant temp from the ecu and the Instrument panel , would save a lot of work , Perhaps there is a problem with the gauge itself ...
