Jaguar Land Rover diesel particulate filter FAQs

Leigh Day is investigating a potential group claim against Jaguar Land Rover over allegations that they fitted certain diesel vehicles with "defective diesel particulate filter systems (DPF) systems"

Frequently asked questions

The DPF system is built to regenerate and clean any excess build-up of soot and pollutants in the vehicle exhaust. A defective DPF system will fail to correctly regenerate, clogging the system and decreasing the engine performance of the vehicle.

When the DPF system is clogged, this can make the vehicle slower and less road safe. Soot also contributes to air pollution meaning the vehicles are less likely to meet advertised environmental standards.

We will be bringing the claim against Jaguar Land Rover Automotive Plc and any other relevant Jaguar Land Rover entity, as well as authorised Jaguar Land Rover finance companies or dealerships who have sold, leased or financed defective vehicles.

We have become aware that Jaguar Land Rover have fitted certain vehicles with a potentially defective DPF system. This may have impacted the safety and environmental performance of the vehicle. Also, affected vehicles may have to be serviced more frequently and at a higher cost, in some cases even requiring a new engine. If the DPF system is defective, research suggests that the vehicle is also likely to have a lower re-sale value.

The models that are included in the claim are:

  • Land Rover Discovery Sport (L550)
  • Land Rover Discovery (L462)
  • Land Rover Velar (L560)
  • Range Rover (L405)
  • Range Rover Evoque (L538 and L551)
  • Range Rover Sport (L494)
  • Jaguar E-Pace (X540)
  • Jaguar F-Pace (X761)
  • Jaguar XE (X760)
  • Jaguar XF (X260)

The affected vehicles must have been leased or purchased between April 2015 and 2022 (apart from the Jaguar E-Pace X450 which must have been purchased between April 2017 and 2021).

Yes. It is an entirely separate claim to the Jaguar Land Rover emissions claim.

We estimate that our clients may receive thousands in compensation.

The level of compensation you may receive as a result of the claim will be dependent on a number of factors such as:

  • How much you paid for the vehicle;
  • Whether you have paid additional servicing and/or repair costs as a result of Jaguar Land Rover fitting your vehicle with a defective DPF system; and
  • Any depreciation of the value of your vehicle.

We will consider throughout the claim any additional losses you may have suffered as a result of the defective DPF system, and will keep you updated if there are any changes.

We will be bringing these claims on a “no-win-no-fee” basis, representing you on a Damages Based Agreement. You will pay no money upfront for Leigh Day to represent you in your defective DPF system claim against Jaguar Land Rover, and any authorised finance companies or dealerships. If you lose, you will not pay for Leigh Day’s services. If you win, Leigh Day will receive a maximum of 30% (plus VAT and disbursements) of your compensation as payment for representing you. 

Please carefully review the retainer agreement documents, in particular your client care letter, for details of the terms on which we will represent you. If you have any questions regarding your retainer agreements, please contact us on: dpfclaims@leighday.co.uk or 020 3780 0213.

It is difficult to say at the early stages of an English litigation how long the claims might take. Length of claims depends on a number of factors outside our control, including the approach that Jaguar Land Rover and any other defendants will take to the litigation. In our experience, group claims of this type may take two to five years to progress through the Court, but it could take much longer. The length of time the claim takes will depend on any complexities arising within the litigation.

We will update you regularly with more information on the timescale of your case, particularly in relation to timescale for next steps, which can be predicted more accurately.

We are at a very early stage of the claims, where we are gathering information and evidence in relation to the claims.

In due course we are optimistic that we will be in a position to advise you to issue court proceedings. We will be working with other firms who are also instructed in relation to these claims, and between us we are then likely to make an application for a Group Litigation Order. A Group Litigation Order allows for claims with common/related issues to be heard and managed together, rather than on an individual basis, making it far more efficient.

As well as pursuing court proceedings we will explore all possible ways of achieving your objectives, including mediation or some other alternative dispute resolution procedure if appropriate and if Jaguar Land Rover and any other defendants will agree to it.

We will provide all of our clients regular updates, particularly around significant milestones in your claim.

If you have any questions throughout your claim, then you can contact dpfclaims@leighday.co.uk or 020 3780 0213 and one of the team will be able to assist you.

Yes. You can still claim if you have sold your vehicle as long as you can show that you have previously leased or owned the affected vehicle.

Yes. Your claim is not affected if you purchased your vehicle pre-owned/second hand from a registered Jaguar Land Rover dealership.

Please note that clients who have purchased their vehicle pre-owned may be entitled to less compensation than those clients who purchased their vehicles new.

A successful class action was brought to trial against Toyota in the Australian courts in April 2022, and upheld on appeal in March 2023. The action was brought by a representative of the affected group, which comprised of 264,170 vehicles that had been fitted with defective DPF systems. The case was decided in favour of the (representative) claimant, who received an award of damages equal to a 10 percent reduction in the value of their vehicle.

Law firms in Australia have since been bringing class actions against Jaguar Land Rover for fitting their vehicles with defective DPF systems.

We may request your documents that relate to any servicing or repairs that have been done to your vehicle. An example of these documents may be:

  • Service invoices;
  • MOT invoices;
  • Any service documents specifically relating to your DPF system;
  • Engine replacement invoices; and
  • Recall letters.

If you have not yet known of any issues with your DPF system, then that is not a problem and will not affect your claim.

The partner on this claim is Oliver Holland who also oversees our Jaguar Land Rover emissions claim.

The senior associate solicitor on the claim is Renée Wright who will be overseeing the day-to-day running of the claim.
