About the
Citroën Diesel Fraud Claim

What are
defeat devices?

Defeat devices are designed to reduce emissions in order to falsely pass regulatory approval tests. When fitted with a defeat device, the vehicle understands when it is under ‘test conditions’ and emissions are reduced so to pass these tests. However, these ‘test conditions’ do not reflect how the vehicle actually performs when driven in the real world.

Outside of test conditions, the affected vehicles release much higher emissions and their overall performance is much lower. As such, without the operation of a defeat device, the vehicles would not pass the necessary regulatory tests.

PGMBM believes that Citroën deliberately misled its customers as to the real levels of emissions their vehicles produce.

As a result of these vehicles being on the road, adults and children may have suffered respiratory problems from breathing in the high volumes of toxicants found in polluted air.

If you owned or leased a Citroën diesel vehicle, first registered in the UK between 2007 and 2020, you may be able to join the Citroën Diesel Fraud Claim.

Pogust Goodhead (previously PGMBM)  is a top global law firm combining the talents of some of the UK’s leading solicitors and barristers.

We were one of the lead firms in the similar group action against the Volkswagen Group that recently reached a UK settlement of £193M. We intend to build upon this initial success against Volkswagen in pursuing your claim against Citroën.

We are currently bringing claims against Mercedes-Benz, Fiat-Chrysler Automobiles and the Renault Nissan Mitsubishi Alliance, and are at the forefront of group emissions claims and represent over a hundred thousand victims in these actions.

Our expert team will support you throughout the litigation and ensure the process is as simple as possible. We feel strongly that Citroën should be held to account for their actions, just as others involved in the Dieselgate scandal have been, and we are passionate about securing compensation for those affected.

claims globally

Emissions claims around the globe under the Dieselgate scandal have already started to yield results for consumers in the United States, Germany, and Australia.

In the United States, emissions claims settlement awards have exceeded $9.8 billion with victims receiving between $5,100 and $10,000. In one case, as part of the Dieselgate scandal, Volkswagen agreed to buy back or repair more than half a million affected vehicles fitted with illegal defeat devices.

Daimler AG, parent company of Mercedes-Benz, agreed a settlement of $1.5 billion with the US Government and California State Regulators in order to settle similar accusations. In 2019, Mercedes-Benz were also fined €870 million by German prosecutors in addition to 774,000 of its vehicles being recalled.


Some vehicles fitted with defeat devices have been shown to produce up to 40x the legal NOx limits. Pogust Goodhead are investigating reports that the Dieselgate scandal may have led to one million extra metric tons of harmful pollutants entering into the atmosphere yearly.

When released into the atmosphere, nitrogen oxide quickly converts into nitrogen dioxide which absorbs sunlight to create smog. It is smog that can exacerbate health conditions such as asthma, bronchitis and emphysema. The pollutants can also be washed into the ground in the form of acid rain, which can harm wildlife and decimate fragile ecosystems.

Our most frequently
asked questions

We believe that Citroën may have fitted hundreds of thousands of their diesel vehicles, manufactured between 2007 and 2020, with illegal emissions defeat (or cheat) devices. 

The claim follows a number of manufacturers alleged of the same crime as part of the Dieselgate scandal. 

If you have owned or leased one of the vehicles affected, you could be eligible for significant compensation. 

Pogust Goodhead believe Citroën deliberately misled its customers regarding the level of emissions that affected vehicles produced. 

We think customers should be compensated for the following reasons: 

  • A possible decrease in the market value of their car 
  • Nitrogen dioxide can be harmful to children, adults and the environment 
  • Customers may have experienced higher fuel bills and maintenance costs 
  • The performance of these vehicles may have been negatively affected 
  • We believe that Vauxhall has broken the trust of their customers. 

We are fighting for victims of the Dieselgate scandal to be compensated for Citroën’s wrongdoing. 

For this emissions claim, we will strive to win you as much as possible and are aiming to recover the entire cost of your vehicle. 

Whilst there are no guarantees, as this is ultimately a decision for the courts, we are optimistic that we may be able to obtain damages of up to £10,000 per vehicle. 

There are no upfront costs when signing up with Pogust Goodhead. We accept instructions on a No-Win, No-Fee basis, which protects you from paying any costs in the event that we are unsuccessful. 

Under the terms of this agreement, you will only be liable to pay our fees and expenses, as well as those of barristers, funders and insurers, if the case is successful. The exact amount you will pay will depend upon how long the case takes, how much time we need to spend on it, and the level of compensation obtained. 

Unlike some other firms, we cap our fees at a maximum of 50%, inclusive of VAT, of the compensation you receive. Depending on the course of the litigation, it is possible that the actual fee may be as low as 20%. 

If you purchased or leased your vehicle in Scotland, your claim must be made in Scotland.  Our Scottish team are currently considering whether Citroen can be pursued in Scotland. If your claim is pursued by our Scottish team in the Scottish courts, this will also be on a ‘no win no fee’ basis, but different fee terms apply.

If you bought or leased a Citroën vehicle between 2007 and 2020, then it is very likely that you will have a claim. 

Once you have submitted your emissions claim and joined the action, our team will conduct an assessment of your individual circumstances in order to ensure you have a valid claim. 

Our claims process is quick and simple. 

Simply submit your details via the Chatbot on this page by clicking on any of the buttons. If we believe that you are eligible to claim, we will send you a short questionnaire to complete. 

From there, there is not much more that you need to do. Should we need anything further from you, we will let you know, but mostly we will just keep you updated on how the case is going. 

Pogust Goodhead is a top global law firm combining the talents of some of the UK’s leading solicitors and barristers. 

We are one of the lead firms in the similar group action against the Volkswagen Group and are currently bringing claims against Mercedes-Benz, Fiat-Chrysler Automobiles and the Renault Nissan Mitsubishi Alliance. We are at the forefront of group emissions claims and represent over a hundred thousand victims in these actions.  

You will receive the legal documents and the terms and conditions upon signing up. We are intending to run this case as a group action, meaning that we bring all of our clients’ cases forward together. 

Should the Citroën NOx Emissions Group Litigation not be successful, then as long as you have stuck to the terms and conditions set out, you will not pay a penny. We take out an insurance policy to protect you against the defendants’ legal costs in the event that the case is unsuccessful.

This is simply the fee stipulated in return for our agreement to act on your behalf. 

Litigating against Citroën will not be as straightforward as other types of claim commonly pursued, such as a personal injury case. As a result, PGMBM will incur significant time and financial expense in bringing this action.   

In any event, you will always keep at least 50% of your damages. 

It is worth checking whether you have legal expense insurance which would cover a claim of this nature. However, in our experience, these policies typically do not cover group actions, have insufficient levels of coverage, and contain restrictive terms which would prevent us acting in your best interests. We will, however, investigate where necessary. 

Whilst PPI claims historically took just a few months, this was because they followed years of investigation by the governing regulatory body as well as heavily contested and protracted litigation – which brought the scandal to light. 

As a claimant in this case, you are part of the initial case being put forward against Citroën. 

We cannot guarantee a timescale for this group action, but we will aim to progress your claim as expediently as possible. 

Pogust Goodhead recently opened a Scottish office, where we will pursue diesel emissions claims for our clients who purchased or leased their vehicles in Scotland.  The Scottish team are currently considering whether Citroen can be pursued in the Scottish courts.
