Volkswagen diesel owners appear ready to accept the maker's settlement offer to buy back their vehicles.

American diesel owners have soundly embraced the settlement offer that Volkswagen negotiated with federal and California regulators in June, a deal that could see the maker buy back the majority of about 475,000 diesel vehicles sold in the U.S. with faulty diesel engines.

Meanwhile, the embattled automaker’s 652 U.S. dealers are asking a federal judge in California to approve their own settlement of $1.2 billion.

“There is resounding support for this consumer class settlement and the substantial benefits it provides,” said Elizabeth Cabraser, a class-action attorney representing consumers who had purchased VW products equipped with a 2.0-liter turbodiesel engine, in a statement.

The two settlements were the result of lawsuits triggered by the revelation in September 2015 that Volkswagen had equipped those vehicles with a so-called defeat device. The software code was capable of detecting when the vehicles were undergoing emissions tests and then sharply reducing pollution levels. In normal operations, however, the vehicles would exceed regulatory mandates by dozens of times.

In June, VW agreed to pay $14.7 billion to settle legal action brought by the Environmental Protection Agency, the Federal Trade Commission, the U.S. Justice Department and the California Air Resources Board. Of that, about $10 billion is to be used to either buy back those vehicles or bring them into compliance with emissions rules. At the moment, VW is still trying to come up with an acceptable fix.

So far, 311,209 owners have registered for the settlement offer. Another 3,298 owners have opted out of the deal, giving them the option to sue individually or take other actions, attorneys handling the class-action lawsuit said. The deadline for opting out ended on Sept. 16.

Consumers soon will be able to begin collecting payments for their vehicles if they prefer a buyback. They have up to two years to decide which option to seek, and some are reportedly waiting to find out if VW eventually will come up with a repair plan that the EPA and California regulators will approve.

A final decision by the judge overseeing the case in a federal court in San Francisco is expected on Oct. 18.

Separately, the court will consider a request by attorneys representing those 652 dealers to accept VW’s offer of $1.2 billion compensation. The franchisees sued the maker in the wake of the diesel scandal on a variety of grounds, including lost sales and a decline in the value of their showrooms.

Even if the courts give final nod to the settlements, however, VW’s legal problems are far from over. The carmaker still has to reach a deal covering the more upscale 3.0-liter diesel that it also rigged. And VW is facing an ongoing criminal investigation here in the U.S. A former engineer recently pleaded guilty for having helped come up with the defeat devices. He is planning to assist the government as its probe continues.

German prosecutors are also moving forward with an investigation that is targeting, among others, former Volkswagen AG CEO Martin Winterkorn.
