MC57F82748 ADC offset

My customer discovered an issue with the MC56F82748 processor that they are using.  When they probe the input pin on the microcontroller, we see an offset of 40 mV between the value the multi-meter reads vs the voltage the ADC peripheral provides.  The offset is consistent as we change the input voltage, but there is no information in the datasheet about a voltage offset.  Is this something they should be seeing and is there a spec for this.
