Check if your vehicle may be affected

Check quickly and easily whether your Vauxhall vehicle may be affected.

Monitoring shows that when the vehicles are driven on the road, they emit many times more levels of toxic NOx gases than under test conditions.

This is extremely damaging, as increased levels of NOx contribute to air pollution which is reported to be the largest environmental risk to UK public health and is linked to as many as 64,000 early deaths a year.

The claims are being investigated on behalf of people who leased or owned Vauxhall, Peugeot or Citroën diesel vehicles. The claims could be worth up to 75% of the purchase price of the vehicle for each owner.

What is the scandal?

In October 2018, the German Federal Motor transport Authority (KBA) identified the presence of inadmissible defeat devices in a number of Vauxhall vehicles and found that “[due to these devices] increased NOx emissions can occur when the vehicles are in operation”. As a result, the KBA ordered a mandatory recall in Germany.

Despite this however there has still not been a recall in the UK. As a result of this there are potentially hundreds of thousands of unlawfully polluting Vauxhall vehicles still on the roads in the UK.

Peugeot and Citroën vehicles have also performed poorly when subjected to emissions testing by the regulators. In February 2017, the French DGCCRF recommended the prosecution of PSA Group (Peugeot and Citroën’s parent company).

In September 2017, Le Monde claimed it had seen the DGCCRF final report and that it had identified what appeared to be cheat devices in Peugeot and Citroën Euro 5 vehicles, and a deliberate strategy since 2010 of seeking to disguise the cheat device to make it “less obvious and visible”.

There have also been recalls of Peugeot and Citroën vehicles on the grounds that “the calibration of the engine management software could result in emissions of NOx which do not comply with the regulatory limits”.

We believe that owners of the affected vehicles should be compensated because they were mis-sold these vehicles, which were advertised as being more environmentally friendly with lower NOx emissions. Increased levels of toxic nitrogen dioxide emissions are harmful to the environment and to the health of children and adults.

We are fighting for compensation on behalf of owners of Vauxhall, Peugeot and Citroën vehicles who we believe were deliberately misled over the environmental performance of their vehicles.

More information about the claim

Leigh Day is joint-lead law firm in the emissions litigation on behalf of UK Volkswagen owners, who recently won the first round of their emissions case against Volkswagen in the UK High Court.

In April 2020 the High Court in London found that the decision by the KBA, the German road vehicle authority, that the software was a ‘defeat device’ was binding in the English High Court.

We have also been instructed by thousands of owners of Mercedes, Renault and Nissan vehicles to pursue emissions claims against those manufacturers.
