If you bought or leased a diesel Mercedes car, van or taxi that was manufactured between 2009 and 2019, you can join the claim.

You might have been notified by Mercedes that your car can be recalled. You can join the claim whether you have received this notification or not, as long as you bought or leased a diesel Mercedes that was manufactured between 2009 and 2019.

We are an English law firm and the claims we are proposing to bring in the first instance will be in the English courts on behalf of claimants in England and Wales. We are working with Scottish and Northern Irish lawyers and intend to bring claims in those jurisdictions too, when possible. Please complete the questionnaire and we will be in touch in due course.

If your vehicle is diesel and was manufactured by Mercedes between 2009 and 2019 it may be affected. You can complete the questionnaire and we will be in touch to let you know if you are eligible to bring a claim.

Harcus Parker is acting for owners of Mercedes-Benz cars, vans and taxis which are alleged to have been fitted with defeat devices, different in form but similar in effect to those used by Volkswagen. Defeat devices allow cars to detect when an emissions test is being carried out and reduce emissions accordingly. Often, when the cars are driven in the real world, emissions will be many times higher than the regulated limits.

NOx emissions have a real impact on people’s health and on the environment: they are a contributory factor in things like childhood asthma and acid rain. There is also a wider issue of corporate responsibility at play here. We believe strongly that companies like Mercedes should not be allowed to ignore important environmental rules for the sake of profit.

Fill out the form on our website here. You will also need to agree to and sign our terms and conditions.

There are many reasons to join the claim, but we think these are the 4 most important:

  • Health – NOx is a pollutant which has been linked to an array of diseases.
  • Environment –NOx emissions are closely associated with acid rain and smog.
  • Accountability – Mercedes could have found a solution and provided vehicles which were suitable for us in our towns and cities, but instead it appears to have cheated.
  • Compensation – you could be entitled to thousands of pounds in compensation if the claims succeed.

Yes. You can still join the claim if you have sold your vehicle, but the amount you can claim might be affected.

Yes. You should do what you would normally do if you were not part of the claim. You can stay part of the claim if you sell your car, but it might have an impact on how much you can claim. If you sell your car you should retain copies of documents which prove that you once owned the car and which record details of the sale.

Yes. Please tell us about both vehicles when you register. You should fill in the form for one vehicle and then select the option at the end to repeat the process.

Yes. You can join the claim if you bought the vehicle on finance.

Yes. You can join the claim if you leased (or lease) the vehicle.

Yes. You can join the claim if you bought the car second hand, but the amount you can claim might be affected.

The exact amount will depend on a number of different factors, including how much you paid for the car and if you have sold it, how much you received for it, but we estimate that claimants will be entitled to several thousand pounds.

No, but certain types of claim have ‘limitation’ deadlines, which will mean that if you wait to join the claim you may be unable to claim some or all of the compensation which might otherwise be available to you.

It is difficult to put a time frame on the claim, but we hope to have a result within the next two years. Legal cases can take a long time to resolve.

There is no up-front cost to join the claim. We are acting on a no-win, no-fee basis which means that you will only have to pay us if you are successful. If you are successful you will pay us 40% of your damages, plus VAT. We will also cover the costs involved in bringing your claim to trial, but you will only have to pay us for those to the extent that we can recover them from the defendant.

It is very important that you read our full terms and conditions and other documents provided when you sign up. If you have any questions about any of the documents you can email us at mercedes@harcusparker.co.uk and someone will get back to you.

If we lose you will not have to pay our fees or pay us back for the costs involved in bringing your claim to trial, but the usual rule in English litigation is that the losing party pays the costs of the winning party. We will make sure that we have insurance in place to protect you if the claim is unsuccessful, but there is a small risk that you may not be covered, for example if the insurance fails.

The documents we ask you for will depend on how you owned the vehicle. We will ask you to provide proof of the purchase or lease, or, if you bought the vehicle on finance, your finance paperwork. If you have sold the car we will also ask you for some documents showing the details of the sale.

Almost certainly not. A small number of claimants might be asked to give evidence, but this is only likely to be a few out of thousands of claimants.

You should do whatever you would do if you were not claiming. We do not know what effect (if any) the fix might have on the vehicle. You can still be part of the claim, whether your car is ‘fixed’ or not.

Yes. You can cancel within 14 days of joining the claim without incurring any costs. If you decide to cancel you will need to notify Harcus Parker in writing – when you sign up you will be provided with a cancellation form that you can use.

Yes, you can join the claim if you purchased of leased your vehicle under the Motability Scheme.
