NB: Requires a MobilScan OBD adapter - get it from www.mobilscan.dk. It will not work with other adapters. We have apparently not been sufficient clear about supported cars: As this is an OBD adapter, only EOBD/OBDII compatible cars are supported. In EU, all cars sold since 2001(gasoline)/2004(diesel) are required to be EOBD/OBDII compatible. As far as we can tell, most brands comply, but if you have a French car, you may want to check its compatibility. You may have luck with older cars, too.
