What is the claim about?

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. We believe that this software is unlawful under UK law and we are planning on bringing legal claims for compensation on behalf of consumers who purchased those vehicles that were affected.


What did Mercedes do?

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.

The KBA (the German road vehicle authority) found that Daimler, the parent company of Mercedes, had used a software to alter diesel emissions. It ordered Mercedes to recall those vehicles that were affected. The German Courts also concluded that Daimler have also been using a prohibited defeat device.

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 current position?

We have now been approached by over 12000 owners of affected cars.

We have secured funding from commercial providers to ensure we have the resources available to instruct the best experts and barristers and to have a large enough legal team to ensure that are our clients get the best service possible.


Can all Mercedes owners bring a claim?

Only people who bought or leased an affected vehicle are able to bring to a claim. Not every Mercedes vehicle is affected. If you think your vehicle is affected, or if you think you may be but are not sure, please complete our online form and a member of our team will contact you.


Which vehicles are affected?

If you bought or leased a diesel Mercedes-Benz vehicle between 2009 and 2018, you can apply to join the claim. Please complete our online vehicle registration checker below, to confirm if your vehicle has been affected.


Does this apply to petrol or diesel vehicles?

This claim only relates to diesel vehicles.


How can I check if my vehicle is affected?

You may have already received a recall letter confirming that your vehicle is affected.  You can also complete our online vehicle registration checker below, to confirm if your vehicle has been affected.


What do I need to do?

Complete our form as fully as possible. We will need you to provide us with your vehicle registration number so that we confirm if your vehicle is affected.


What is a VIN?

The VIN is a 17-digit number starting with a 3-letter code.  For example, for Mercedes-Benz cars, these letters could be WDB or WDC, or WDB or WDF for Mercedes-Benz Vans. You should be able to find the VIN at various locations on your car. Frequently you can find your VIN number in one of the following locations: on the driver's side door jam (sometimes on the passenger's side), under the windshield on the driver's side, near the firewall of the vehicle or on the steering column.


What will it cost me?

By completing the form you are simply registering an interest to join the group claim, and no obligation to pay a fee. We will be bringing these claims on a 'No Win-No Fee' basis. This means that we’ll deduct up to 31% (inclusive of VAT) of your damages if the claim is successful, but if the claim is lost you will not have to pay anything. Our Success fee, the insurance premium and the funders’ fees will never be more than 31% of your costs, irrespective of the number of claimants within the group.

Once you have completed a form and we have checked that you are eligible to bring a claim, we will send you a copy of our funding agreement for you to review.

Can I use my own legal insurance?

You may have other sources of funding your claim other than the funding package we are offering. For example: 

Legal expenses insurance. Many home insurance products include legal expenses insurance either automatically or as anoptional add-on. You should contact your insurers to check.
If you are a member of a trade union, you should check whether the union will fund you.
If you have such an alternative source of funding, then it may be cheaper for you to use it than the funding package we areoffering. We are not offering to act via such legal expenses insurance/union funding, so if you wish to use it you may need to instruct another firm.
 


Can I bring a claim if I bought my vehicle on finance?

Yes, provided you bought an affected vehicle, you are able to bring a claim.

Can I bring a claim if I have a company car?

Yes, if the contract is in your name and the vehicle is affected, you are able to bring a claim.

Can I bring a claim if my vehicle is leased?

Yes, if the contract is in your name and the vehicle is affected, you are able to bring a claim.


I have sold my vehicle, can I claim?

Provided you are able to confirm that your vehicle is affected, yes. You will need to check your vehicle registration number and we will ask you to provide us with your vehicle purchase documents.


Can I claim for more than one vehicle?

Provided all the vehicles you want to claim for are affected, yes. We need you to complete a separate questionnaire for each of your vehicles.


Does it matter where I bought my vehicle?

No, it does not matter where you bought your Mercedes-Benz vehicle as long as it was bought in England & Wales. You are eligible bring a claim against the manufacturer whether you bought your vehicle from a Mercedes-Benz showroom, from a private seller or from a third party dealer, or if you bought the car for business purposes.


Am I able to claim is my vehicle is second hand?

Yes, you will still be able to claim whether your vehicle was bought new or second hand.


Why should I instruct Leigh Day?

Leigh Day is one of the country's leading law firms, we are not a claims management company. Bringing group actions on behalf of consumers is one of Leigh Day's key areas of specialty and we have been involved in some of the largest group actions ever taken in the UK.
 
We are joint-lead lawyers in the emissions litigation on behalf of UK Volkswagen owners, and recently won the first round of the case against Volkswagen in the UK High Court.

In that case we 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.
