Mitsubishi L200 DPF Problems

Owners of the 2019 Mitsubishi L200 have been reporting a recurring issue regarding the Diesel Particulate Filter (DPF), which is an essential component in controlling the emission of diesel engines. Despite being relatively new with a mileage of around 34,000, a notable number of these trucks are facing DPF problems which signal through a persistent hazard light, even after undergoing regeneration cycles. This light is causing concern especially for those planning to undertake long journeys soon. In this article, we delve into the details of the problem and explore the potential solutions available.

Understanding the Problem

The Role of the DPF

DPFs are installed to trap soot particles and prevent them from being released into the atmosphere, helping to maintain a greener environment. While DPFs are a necessary environmental safeguard, they can pose issues, particularly when driving habits involve a lot of short journeys which prevent the DPF from effectively burning off the accumulated particles.

The Issue at Hand

Owners find themselves cornered, with an imminent travel schedule and a DPF hazard light that refuses to go off. In addition to this, getting an appointment for a DPF clean at a local garage on short notice has proven to be quite challenging. The urgency to find a reliable solution is compounded by the fact that a malfunctioning DPF can lead to the vehicle operating in limp mode, reducing the performance drastically.

Potential Solutions

DPF Cleaning and Maintenance

While contemplating a costly DPF clean with mixed success rates, owners have explored the idea of utilizing diesel additives specifically designed for DPF cleaning. These additives can sometimes assist in clearing minor blockages and are certainly worth considering as a first step in troubleshooting the issue.

Forced Regeneration

Reaching out to a Mitsubishi dealer for a forced regeneration is another option. This process, albeit potentially costly, might resolve the issue, especially if the problem is not severe. It is recommended to inquire whether this service would be covered under warranty to potentially save on costs.

DPF Removal: A Controversial Choice

A more drastic measure is to consider removing the DPF; however, this route has stirred a range of responses from the community. Removing the DPF can lead to legal repercussions, including failure in the MOT test and making the insurance invalid, not to mention the environmental implications.

Preparing for Your Trip: Safety First

Before embarking on any long journey, it is vital to ensure that your vehicle is in good condition. Undertaking a motorway run of around 50 miles before the main trip can sometimes help in clearing out the DPF if it is not heavily tarred. However, it is vital to note that if the DPF is extensively tarred, this might not work, and continuing to drive might cause further damage, including potential turbo failure. Therefore, conducting a trial run can give you a sense of the current condition of the DPF and guide your next steps accordingly.

Conclusion

Owners find themselves in a difficult situation navigating the persistent DPF issues with the Mitsubishi L200. While there are several routes to explore, from utilizing additives to a complete DPF clean, each comes with its own set of challenges and potential outcomes. It is recommended to approach a solution with a full understanding of the possible repercussions and a focus on both environmental responsibility and legal compliance.

As you navigate this challenge, we wish you a safe and hassle-free journey, encouraging all drivers to adopt driving habits that support the longevity and functionality of the DPF system, thereby contributing to a healthier environment for all.
