    Have a 1997 v40 cd auto
    when engine is warm it will not start without pressing the throttle
    and then leaving it running fast without engaging drive, then after a
    few moments it settles to a steady tickover.
    I have been told it is the heat sensor sending an incorrect reading
    to the coldstart system? but if so is this the same temperature sensor
    for the dashboard guage?.

    appreciate help
    Thanks

    check the inlet track for leaks. A weak running engine will do this.
    ( from experience I had a leak on a flashlube system that caused these
    exact symptoms on a V70 1997 2.5 LPT. )

    fixing the split pipe fixed it all overnight
