HGV DPF Cleaning and Lorry Exhausts

We provide lorry exhaust checks and HGV DPF cleaning support for commercial vehicles. Our team can inspect exhaust faults, investigate warning lights, and advise on the best repair or cleaning option.

Why Clean a HGV DPF Cleaning?

A diesel particulate filter, often called a DPF, is part of the exhaust system on many diesel HGVs. It captures soot from the engine before it leaves the exhaust.

Over time, the DPF needs to clear this soot through a process called regeneration. If this process does not happen correctly, the filter can become blocked.

A blocked DPF can cause warning lights, loss of power, poor fuel economy, limp mode, and failed regeneration. In some cases, the vehicle may struggle to complete normal journeys until the issue is fixed.

Signs of Lorry Exhaust or DPF Problems

Exhaust and DPF faults can appear in several ways. Some are easy to notice, while others need diagnostic checks.

Common signs include:

If your lorry shows any of these signs, it is worth booking an inspection before the issue becomes worse.

What Does Our Exhaust and DPF Service Include?

Our service is designed to find the cause of the issue, not just clear a warning light. We combine diagnostic checks with practical inspection.

Exhaust System Checks

We can inspect the exhaust system for leaks, damage, corrosion, loose fittings, and failed sections. A leaking exhaust can increase noise, affect emissions, and create safety concerns.

If repair or replacement is needed, we will explain the issue clearly.

DPF Diagnostics

A warning light does not always mean the DPF itself has failed. Other faults can stop regeneration from working. This may include sensor faults, pressure issues, temperature issues, wiring problems, or engine faults.

We can use diagnostic equipment to check fault codes and live data before advising on the next step.

Wiring and Connection Checks

If the DPF is blocked but still serviceable, cleaning may help restore performance. The right approach depends on the level of blockage and the reason it happened.

We can inspect the system and advise whether DPF cleaning, further diagnosis, or repair work is the best option.

Preventing Repeat DPF Issues

If a DPF blocks again soon after cleaning, there is often another problem. The cause may be linked to driving patterns, failed sensors, engine faults, air leaks, or poor regeneration.

Our team can help identify why the blockage happened, so the same issue is less likely to return.
