Mercedes-Benz emissions claim

Leigh Day Mercedes-Benz AdBlue emissions claim

If you are one of over 84,000 drivers in the UK who own or lease a Mercedes-Benz vehicle,  you could be entitled to compensation.

Leigh Day are investigating a potential group claim against Mercedes-Benz over an alleged ‘cheat device’ fitted on some of their cars in order to artificially reduce emissions to pass EU emissions tests.

The claims, being investigated on behalf of owners of Mercedes vehicles could be worth up to 75% of the purchase price of the vehicle.

We are fighting for compensation on behalf of owners of Mercedes vehicles who we believe were deliberately misled over the environmental performance of their vehicles.

This legal challenge follows the German automotive regulator’s ruling that Mercedes Daimler cheated EU emissions tests. 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 nitrogen dioxide emissions are harmful to the environment and to the health of children and adults.

What is the Mercedes-Benz emissions claim?

In June 2018 the KBA, the German road vehicle authority, found that Daimler, the parent company of Mercedes, had used illegal software to alter diesel emissions.

Why choose Leigh Day?

Leigh Day are leading experts in vehicle emissions group claims.

Leigh Day are joint-lead lawyers 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.

Leigh Day argued that Volkswagen had deceived car owners as to the compliance of vehicles with EU Emissions Regulations.

Lawyers for the UK drivers argued that Volkswagen engines contained defeat device software which sensed when the vehicle was being tested and so artificially reduced emissions in order to pass that test.

Volkswagen have always argued that the software did not meet the legal definition of a defeat device and so was not illegal.

However, 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.

The court also agreed that the fact that the engine operates in different modes during the emissions test means that it contained a ‘defeat device’ under the EU emissions Regulations.
