Volkswagen saw its sales in the UK fall almost 10% last month as the emissions scandal began to takes its toll.
Figures from the Society of Motor Manufacturers and Traders (SMMT) said Volkswagen sales fell 9.8% in October. Of the other car manufacturers owned by VW, Skoda sales fell 3% and Seat dropped 32.2%.
However, its more luxury brands - Porsche, Audi and Bentley - all saw sales rise.
It came as overall sales of new cars in the UK fell for the first time in more than three years. The SMMT said sales fell 1.1% in October compared with the previous year. New car sales had risen for 43 consecutive months before October.
Despite the effects of the emissions scandal, Volkswagen wasn't the only manufacturer to experience a sharp drop in sales. Vauxhall saw their sales decline 16% and Ford almost 9%.
Speaking to the BBC, Mike Hawes, chief executive of the SMMT, said: "Given the issues they've [Volkswagen] been experiencing over the last six weeks or so, some small adjustment is to be expected."
However, Auto Express believes Volkswagen's emissions scandal could have a negative impact on the car industry as a whole.
Steve Fowler said: "A decline in sales had to happen eventually - three-and-a-half years of growth - it's going to slow at some stage. But I do think the Volkswagen emissions scandal has had a clear effect.
"We know a lot of people who've been in touch with us who are delaying a purchase. They still want to buy a car, but they're just not sure what they should do and frankly, who they should trust at the moment."
