I have tried repeatedly to reregister my LPG converted Range Rover in France, but have failed each time with the DRIRE. - Although the UK installers insist that the LPG installation is EEC approved, the DRIRE insist that I have nearly 2000 euros worth of work done on the LPG installation before they will issue the Certificat de Conformité. As the car does not appear to be worth this amount of money, I shall probably have to return it to England to sell it there. However, a friend of mine has recently heard that since 1 July 2005, Certificat de Conformités are no longer required. Apparently, if the car passes its Controle Technique, it is judged to conform. Can anyone confirm whether this is true please?
