For airbag light removal we would strongly reccomend using the Autel AA101 tool.
For fault code reading/scanning the main sellers are the GS500, MS509, U381 & Renault CAN CLIP. The U381, GS500 & MS509 can be used as hand held devices to read codes & live data, however the Renault CAN CLIP scanner will need to be hooked upto your laptop. All laptop based scanners/readers come with all cables & software to get you up and running straight away.
