Volkswagen (VW) said it was in talks to discuss a settlement with German vehicle owners who are suing the carmaker over excessive pollution caused by VW’s diesel cars.

In 2015 the carmaker admitted to using manipulated engine management software to mask excessive pollution levels in its diesel cars, sparking a raft of prosecutions and lawsuits that have led to at least 30 billion euros in legal costs and fines. “Volkswagen and the Federation of German Consumer Organisations  have agreed to enter into discussions regarding a possible settlement,” the carmaker said.

“The discussions are at a very early stage, and there is no guarantee that they will result in a settlement. Both parties have agreed that the discussions should remain confidential.”

German consumers have had less success than vehicle owners in the United States in securing compensation from VW because German cars did not lose their road worthiness certification in the wake of the diesel scandal.

In Germany VW’s diesel vehicles retained their road worthiness certification if customers agreed to an update of vehicle engine management software, leading VW to take a different approach to compensating consumers.

Volkswagen has attracted bids from Europe’s Innio, Japan’s Mitsubishi Heavy and US-based Cummins for its MAN Energy Solutions, which makes diesel engines for ships and power generators, people close to the matter said.

MAN Energy Solutions was originally a part of VW’s trucks brand MAN, but some of MAN’s assets were transferred to Volkswagen last year as part of efforts to streamline Traton ahead of the unit’s listing.
