    Hope someone can help me on this
    My 2001 speed triple 955i does not seem
    to be getting warm . Let me try and explain
    I do 35 miles to work and back each day
    and the temp gauge does not move much
    past the cold is this right ? I'm used to the
    needle sitting around the middle mark

    Sounds feasible for this time of year. You can check that your gauge is functioning by putting the temperature sender wire to earth & the needle should sweep across the dial.
    Could be a faulty temperature sender, which would mean that the engine is getting up to temperature as normal but being faulty it is sending false information to the gauge. Or another possible fault could be a thermostat stuck open?
    Normally the thermostat is shut until the coolant within the engine reaches the desired temperature that the thermostat is manufactured to open at, the thermostat then opens allowing the hot coolant to flow into the radiator to be cooled & back round again & so on & so forth. If the thermostat is stuck up the coolant will flow continuously & therefore struggle to reach the "normal" operating temperature.

    Hope this helps?

    Thermostat stuck open would be my guess

    When the engine is hot check to see if hose to rad and rad is too, this should indicate the thermostat has opened
