It appears the whole Volkswagen “dieselgate” scandal in the United States might be affecting sales across the Pond, too. Autocar UK reported that the Das Auto brand has seen a near-20% sales slump in Britain in November, compared to the same month last year, according to new car registration figures published by the Society of Motor Manufacturers and Traders (SMMT).

Wolfsburg registered 12,958 cars in Blighty last month, a drop of 19.99% compared to the 16,196 cars it rolled out of dealer forecourts in November 2014; fellow VW Group brands Audi, SEAT and Skoda saw similar decreases of 4.41%, 23.83% and 10.98% respectively. This is despite UK car sales as a whole rising 3.8% in the same period, with 178,876 cars registered last month.

However, Volkswagen is reportedly still bullish of its fortunes, as it expects the overall year’s sales to be up on 2014 by the year end. “The gap is not a true representation of our overall sales trend,” said a spokesperson. “These ‘spikes’ in volume manufacturer results can be explained by, for example, delivery schedules of major customers and suchlike.”

Indeed, despite the poor November showing, Volkswagen’s sales for the year to date are up 4.50% compared to the same period the year before. As for the other VW Group brands, Audi’s sales are up by 4.37%, but both SEAT and Skoda are down by 8.16% and 1.40% respectively.

The news comes hot on the heels of a similar sales drop of almost 25% suffered by Volkswagen in the US – it sold 23,882 cars there last month, 8,000 units less than in November 2014. As for year-to-date performance, Volkswagen managed to sell 318,484 units, compared to 332,912 last year over the same period.
