I'm not sure what you're asking, but if you mean that you are getting an OBD-II diagnostic code of P0128 from your Volvo S40, that code corresponds to a problem with coolant temperature. On a first generation Volvo s40 (99-04), this usually means that the thermostat or electronic coolant temperature sensor are malfuctioning or have failed.
