A DiCE will also read and record live data. My car had the later 2002- Bosch ETM which CAN be replaced without Volvo making any software alterations. They are not prone to failure though I did "§§§§ in the wind" by changing it on a hunch for a 2008 unit and it made no difference.
My signature should now read "Bog standard 2005 D5". Must change that soon.
