Modi drove to Advani's residence for the meeting which comes days after Advani showed his displeasure at being sidelined over the Modi issue by resigning from three key party posts.
Advani, however, later withdrew his resignation following a telephonic talk with RSS chief Mohan Bhagwat and persuasion by BJP leaders.
Modi is in Delhi primarily to meet Planning Commission Deputy Chairman Montek Singh Ahluwalia and finalize the state's annual plan.
