The Ultimate Guide to DPF Cleaning: Restore Performance with a High-Pressure Chemical Clean

Do you own a diesel vehicle and are based in Liverpool?

One of the most critical yet overlooked components of these types of vehicles is the Diesel Particulate Filter (DPF). Over time, DPFs become clogged with soot and ash, leading to less power, poor fuel economy, warning lights on your dashboard, and even MOT failures.

At Voytech Tuning, we offer a professional high-pressure chemical DPF cleaning service that brings your system back to life. Using this process, we can improve efficiency and save you from costly repairs or replacements. 

We work with clients in Liverpool, Manchester, Blackpool and Chester, Ashton and all nearby areas. Highly rated by our previous customers, you can trust us for a premium service. 

What Is a DPF and Why Does It Get Blocked?

A DPF is a filter fitted to diesel vehicles designed to trap and reduce particulate emissions (mainly soot) from exhaust gases. It plays an important role in meeting the latest emissions standards and protecting the environment.

Unfortunately, DPFs aren’t self-cleaning in all circumstances. If you often take short trips, get stuck in stop-start traffic or spend time idling, the filter doesn’t get hot enough to regenerate (burn off soot). The result? Unwanted blockages. 

Once the filter becomes clogged, you’ll notice reduced power, more fuel being used up, and possibly even the activation of ‘limp mode’. Limp mode (also known as limp home mode) is a safety feature in modern vehicles. When the engine control unit (ECU) detects a serious problem—especially with critical systems like the transmission, turbocharger, or emissions controls (including the DPF), it restricts engine power to prevent further damage.

Signs Your DPF Needs Cleaning

Dealing with this issue early is key. It helps to look out for:

• A loss of engine power

• Increased fuel consumption

• DPF warning lights on your dashboard

• A strong stench of diesel fumes

• Plumes of smoke from the exhaust

• Poor throttle response

If you’re spotting one or more of these, it’s time to act before damage spreads to your turbocharger, EGR valve or engine.

Why Choose High-Pressure Chemical DPF Cleaning?

Unlike basic regeneration or off-the-shelf cleaning products, our high-pressure chemical clean goes deep into the structure of the filter. It uses professional-grade cleaning agents combined with high-pressure equipment to flush out soot, ash, and contaminants. This means we can fully restore the DPF to full working order..

Here’s a few reasons to book this type of cleaning:

• Deep Penetration. Chemical agents break down hardened soot and ash that can’t be burned off or flushed with fuel additives.

• High Pressure forces the cleaning solution through the filter matrix, dislodging even the most stubborn build-up.

• On-Vehicle or Off-Vehicle Options. Flexible solutions depending on the level of blockage and your preferences.

• Immediate Results. Restored flow rates and pressure readings before the car even leaves our workshop.

Our DPF Cleaning Process

At Voytech Tuning, our technicians are fully trained and equipped to carry out DPF cleaning with the utmost care. Here’s what the process typically involves:

1. Initial Diagnostics. We run a full system scan to assess DPF blockage levels, sensor readings, and any fault codes.

2. Backpressure Testing. This test confirms how bad the issue with the DPF is, helping us determine the best cleaning method.

3. Chemical Application. Specialised chemicals are injected into the DPF to break down and dissolve soot and ash.

4. High-Pressure Flush. A powerful flush forces the loosened debris out of the filter, completely clearing it.

5. Post-Clean Test & Regeneration. We reset the system, run a forced regeneration (if needed), and recheck pressure levels to confirm success.

6. Final Report. You receive a full breakdown of before-and-after readings, the fault codes cleared, and performance improvements.

The Many Benefits of a Clean DPF

A well cleaned DPF makes a huge difference to the health of your vehicle and its performance. Benefits include:

• Restored engine power

• Lower fuel consumption

• Extended DPF lifespan

• Lower emissions

• Prevention of future engine damage

• Peace of mind at MOT time

Another advantage? It’s a fraction of the cost of DPF replacement, which can easily run into the thousands!
