The emissions' testing scandal will have no discernible impact on Volkswagen residual values, says CAP.

Dylan Setterfield, senior forecasting editor at CAP, said: “We do not expect there to be any significant impact on used values for VAG models in the UK as a direct result of the US emissions scandal.

"The last global recall was the Toyota/Lexus issue, and despite the fact that this had serious safety implications, there was no discernible impact on used values.

“It is also far from certain that VAG are the only ones to have employed such technology on their vehicles in the USA.

“UK consumers remain relatively unaware of nitrogen oxide (NOx) emissions and are far more accepting of diesel technology than their counterparts in the USA.

"The overriding view is that diesel vehicles are more economical than their petrol equivalents (even if this is not always the case), and the torque characteristics of diesel engines are generally popular with drivers.

“There is already wide acceptance that official data regarding CO2 emissions and fuel economy are broadly unreliable across the board. This is reputational issue for VW and I’m sure they will take steps to reassure customers and rebuild trust.” 

CAP says it has had a high volume of enquiries from across the industry around potential impacts on used values. 

Setterfield said: “Until the full impact of the issue is fully understood, it is very difficult to plan around the problem. We recommend a watching brief as the situation evolves."
