The deal sets aside USD 10 billion to repair or buy back roughly 475,000 polluting Volkswagen vehicles with 2-litre diesel engines, and to compensate each owner with an additional payment of between USD 5,100 and USD 10,000, the person said.

The person asked not to be identified because the deal will not be filed in court until today, and a judge has ordered attorneys not to talk about it before then.

Owners who pick the buybacks would get the clean trade-in value of their cars from before the scandal became public on September 18, 2015. The average value of a VW diesel has dropped 19 per cent since just before the scandal began. In August of 2015, the average was USD 13,196, and this May it was USD 10,674, according to Kelley Blue Book.
    
The settlement still requires a judge's approval before it can go into effect. The scandal erupted in September when it was learned that the German automaker had fitted many of its cars with software to fool emissions tests and had put dirty vehicles on the road.

Investigators determined that the cars emitted more than 40 times the legal limit of nitrogen oxide, which can cause respiratory problems in humans. Car owners and the U.S. Department of Justice sued.

The settlement also includes USD 2.7 billion for environmental mitigation and another USD 2 billion for research on zero-emissions technology, the person said.
    
The USD 14.7 billion would eclipse the cost of all recent automotive scandals. But VW is still facing billions of dollars in fines and penalties that are not part of the deal.
    
The company has admitted developing sophisticated software that determined when the cars were being tested by the EPA on a treadmill-like device called a dynamometer and turned on the pollution controls. Once all wheels began spinning and the steering wheel was turned, the controls were turned off.
    
The company, which knew the EPA's testing routine, got away with the scam for seven years before being caught by the International Council on Clean Transportation, which hired West Virginia University to test a VW in real roads conditions.
    
The settlement does not include another roughly 90,000 3-litre Volkswagen diesels, which had another version of cheating software.
