Volkswagen is suspending the sale of 4,000 vehicles in the UK in the wake of the emissions scandal.
The company said the vehicles may be equipped with the device that cheated emissions tests in the US.
The move will involve vehicles across the VW group including the VW, Audi, Skoda and Seat brands.
VW said it was a temporary measure and that it intended to return the vehicles for sale once a fix is identified for the cars.
Despite the scandal that began almost two weeks ago, VW customers could still buy vehicles that had the rogue software.
The cars taken off the market represent 3% of VW's stock in the UK.
The company will continue to sell new vehicles, with the latest, cleanest engine technology.
