Range Rover DPF problems and symptoms

Range Rover DPF problems can occur due to issues like clogging, sensor malfunctions, or incomplete regenerations. These problems may trigger warning lights and affect engine performance.

Read on to see the signs, symptoms, common causes, and how you can fix your Range Rover DPF problems.

What models are affected?

Signs and symptoms

Let’s start off by discussing the telltale signs and symptoms that may indicate a Range Rover DPF problem.

If you’re experiencing any of the following issues, your diesel particulate filter (DPF) is likely causing trouble:

  • Loss of power: Your Range Rover may feel sluggish and unresponsive, struggling to accelerate as it normally would.
  • Reduced fuel economy: You might notice that your beloved vehicle is guzzling more fuel than usual, leaving you with an empty wallet and a sad face.
  • Warning lights: The dreaded warning lights on your dashboard might start to illuminate, indicating a problem with the DPF.
  • Increased exhaust smoke: Is your Range Rover puffing out thick clouds of smoke from the exhaust? Well, that’s not a good sign, my friend.
  • Frequent regenerations: If your DPF is clogged or malfunctioning, you might find that your vehicle’s regeneration process occurs more frequently than it should.

List of possible OBD codes

You might come across specific On-Board Diagnostic (OBD) codes related to the DPF.

Here are a few codes commonly associated with these issues:

  • P2002: Diesel Particulate Filter Efficiency Below Threshold: This code suggests that the DPF is not capturing enough particulate matter, indicating a potential blockage or malfunction.
  • P244A: Diesel Particulate Filter Differential Pressure Too Low: The DPF pressure sensor detects a low-pressure difference across the filter, which could be caused by excessive soot accumulation or a faulty sensor.

Common causes

Here’s a list of the usual suspects:

1. Excessive short trips

Constantly driving short distances without allowing the engine to reach adequate operating temperatures can increase soot accumulation in the DPF.

2. Low-quality fuel

Poor-quality diesel or contaminated fuel can leave behind more residues, increasing the chances of DPF blockage.

3. Faulty sensors

Sensors responsible for monitoring DPF performance and regeneration cycles can malfunction, leading to inaccurate readings and improper functioning.

4. Lack of maintenance

Neglecting regular maintenance, such as DPF cleaning, can contribute to the accumulation of soot and ash, hindering the DPF’s efficiency.

5. Failed regeneration cycles

If the Range Rover’s engine control system fails to initiate or complete the DPF’s regeneration process, it can lead to a clogged DPF.

Can it be fixed without a mechanic?

As much as we love to get our hands dirty, sometimes fixing a Range Rover DPF problem without professional assistance can be daunting.

However, you can try a few things before seeking a mechanic’s help.

Keep in mind that these methods may not work in all situations, but they’re worth a shot:

1. Long highway drive

Taking your Range Rover for an extended drive on the highway at higher speeds can help the DPF regenerate by reaching sufficient temperatures.

If you don’t fancy speeding, simply park up somewhere out of the way and continously rev the engine between 2,000 and 2,500 rpms.

2. Using a DPF cleaner

There are specialized DPF cleaners available that can help loosen and remove soot buildup, potentially improving the DPF’s efficiency.

I’ve compiled a guide of the best DPF cleaners that you may find helpful.

3. Manual regeneration

Some Range Rover models offer the option to manually initiate a regeneration process.

Check your Lond Rover user manual for instructions on how to perform this procedure safely.

Parts you’ll need to fix it

If your Range Rover’s DPF problem persists and requires replacement, using DFP cleaners, or professional repair, here’s a list of parts you might need:

Tools you’ll need to fix it

When it comes to fixing any Range Rover DPF problems, having the right tools is crucial. Here are a few tools that might come in handy:

  • OBD-II scanner: An OBD-II scanner is essential for reading and diagnosing the specific OBD codes related to the DPF problem.
  • Wrenches and sockets: You’ll need various wrenches and sockets to remove and install the DPF and other related components.
  • Torque wrench: A torque wrench is necessary for tightening bolts to the recommended specifications.
  • Safety gloves and glasses: Protecting yourself is important, so don’t forget to wear safety gloves and glasses while working on your Range Rover.

How to fix it

Here’s a step-by-step guide to help you get the job done:

  1. Consult vehicle manual: Before starting any repair, refer to your Range Rover’s manual for specific instructions and safety precautions.
  2. Diagnostic scan: Connect an OBD-II scanner to retrieve the specific OBD codes related to the DPF problem. This will help you understand the root cause.
  3. Inspect the DPF: Remove the DPF and inspect it for excessive soot accumulation, damage, or blockage. If necessary, clean the filter or replace it with a new one.
  4. Check sensor functionality: Test the DPF pressure sensor and other related sensors to ensure they’re functioning correctly. Replace any faulty sensors if needed.
  5. Reset error codes: After replacing or cleaning the DPF, use the OBD-II scanner to clear any error codes and reset the vehicle’s engine control system.
  6. Ensure proper installation: Install the new DPF or re-install the cleaned filter, ensuring a secure and proper fit. Tighten all bolts to the recommended specifications.
  7. Test drive and monitor: Take your Range Rover for a test drive to allow the regeneration process to occur. Monitor the vehicle for any recurring issues.

Potential alternative causes

Although we’ve covered the common causes of your Range Rover DPF problems, it’s important to note that every situation is unique.

Several other factors and components can contribute to DPF issues in Range Rovers.

If you’ve followed the recommended steps and the problem persists, it’s best to consult a professional mechanic for a thorough diagnosis.


How often should the DPF be cleaned?

The frequency of DPF (Diesel Particulate Filter) cleaning depends on driving conditions, but it’s typically recommended every 75,000 to 100,000 miles.

Can I drive with a blocked DPF?

Driving with a blocked DPF can lead to engine damage. It’s advisable to address the issue promptly to prevent costly repairs.

Are Range Rovers the only vehicles prone to DPF problems?

No, DPF problems can affect various diesel vehicles, not limited to Range Rovers. Many modern diesel cars and trucks use DPFs.


The loss of power to warning lights, these issues can affect the performance and longevity of your beloved vehicle.

However, you can keep your Range Rover running smoothly with proper diagnosis, regular maintenance, and timely repairs.

Remember, when in doubt, don’t hesitate to seek the assistance of a qualified mechanic to ensure a comprehensive and accurate fix. Happy and worry-free driving!
