Hello there! Can anyone help me with this problem? Took our renault scenic 2003 to garage for new crank shaft sensor and wiring loom to be fitted. Had to enter radio code from service manual. Followed procedure from instructions. Radio came on but bleeps every few seconds and eventually resets back to 0000. Tried a number of times. Did eventually set to CURVE 0? Then when engine started goes back to CODE AND 0000? Any help much appreciated! Radio worked fine before work carried out.
