With almost 9 million vehicles affected by the Volkswagen diesel emissions scandal in Europe, repairing them will take longer than expected.

Out of the 8.5 million cars found in the region, dealers have only fixed 50,000 of them, as a new report published by AutomotiveNews writes, quoting the brand’s sales chief, Fred Kappler, who expects the proposed fix for the Passat to be approved by Germany’s KBA regulator this summer.

We are in deep discussions with the KBA. We are quite optimistic about getting approval in coming weeks“, Kappler said.

It’s expected that the majority of affected diesel-powered cars from Volkswagen, Audi, Porsche, Seat and Skoda to be fixed by the end of this year, but an unknown number of vehicles will continue to emit high levels of CO2 on the roads of the Old Continent, as they will be reportedly repaired in 2017.

After the Dieselgate scandal surfaced last year, Volkswagen came up with a fix, in the form of software updates for the 1.2-, 1.6- and 2.0-liter powertrains, along with a hardware solution for roughly a third of all affected cars.

In the meantime, across the pond, lawyers representing owners of the affected diesel cars and the US government have taken yet another step towards reaching a final settlement, with three objectives on which it will be based that will make VW come up with a fix for the 2.0-liter engines or terminate leases/buy back affected cars, pay compensation to each owner/lessee and contribute to a fund for environmental remediation.
