Series 1 SR3 injected 1500 / Water Temp Sender

I'm still trying to sort out whether or not my MBE ECU (2006) is working correctly. Not many sensors to work with but an EZ one is the water temp sensor. I found a part number on the forum for a Bosch sensor #0280130069 which has the correct plug but doesn't run the motor correctly. The number(s) on the part from my engine is 73355A and 08C4L. I found a similar part number on line that was a Lucas part but the plug was wrong. Can anyone help with something that you've found.
