Hi
I bought a Autel MaxiDiag FR704 which comes with preloaded software for all Rebault, Peugeot and Citreon cars. It cost about £160 but u can download software vfor most other cars and considering Renault wanted £1000 to get my airbag light off e.g. new airbags, pretensioners and ECU, I bought this and with a couple of pretensioners off ebay got my airbag light off. Defo worth considering. It reads all codes and resets the MILs once you have cleared the faults.
Hope this helps
