Volkswagen AG faces a Feb. 2 deadline to submit a repair plan for 80,000 diesel SUVs and larger cars that emit excess pollution, even as it considers buying back some vehicles and a prior fix plan for smaller vehicles was rejected. The second largest automaker still hasn't announced any timetable for winning approval from U.S. and California regulators to address excess emissions in 575,000 2.0 and 3.0 litre U.S. vehicles.
