The world champion had taken the lead on Saturday after Finnish team mate Jari-Matti Latvala hit a rock and had to change a wheel, losing more than two minutes.
Ogier, who also took a bonus point in the final Power Stage, had an uneventful final day and won the gravel event with a one minute 23.1 second advantage over second placed Norwegian Mads Ostberg in a Citroen.
Latvala took third place. Ogier now has 138 points to Latvala's 105, with Ostberg on 66.
The win was Ogier's fourth of the season, with Latvala winning the other two. Volkswagen beat Citroen's previous record of eight wins in a row in Argentina last month.
