Use the DPF Checker
Answer a few symptom questions first. It helps drivers with warning lights, limp mode, smoke, failed regenerations or short-trip issues understand whether assessment should be the next step.
DPF warning light, limp mode or failed regeneration? Start with the DPF checker for fast guidance, or book a diagnostic assessment so the vehicle can be checked before money is spent on the wrong clean.

Choose this if the car already has a DPF light, engine management light, limp mode, repeat failed regeneration or previous repair attempts. Assessment confirms the sensible route before cleaning.
Start with assessment when the vehicle already has warning lights, limp mode or repeat failed regenerations. Cleaning and refurb only come after the fault picture makes sense.
The recommended booking route when warning lights, limp mode or repeat failed regenerations need a proper diagnostic check.
Cleaning is considered after the fault pattern supports it. If you are unsure, run the checker or book assessment first.
For heavier cases, ash loading or contamination concerns. Assessment confirms whether this route is actually needed.
Fault codes, live data, pressure readings and symptom review.

Suitable when the blockage pattern and root cause support cleaning.
Diagnosis-led DPF cleaning, not guesswork-led.
The most suitable route is confirmed before work begins.
For more advanced cases where a lighter route is no longer enough.
Restore a dependable and sensible repair path where appropriate.
Assessment confirms whether this is the correct option.
A professional process built around diagnosis, consistency and recommending the route the vehicle actually needs.
Our DPF cleaning approach has been developed in-house through research and development, alongside specialist input, to support controlled and consistent cleaning where appropriate.
We aim to identify the underlying cause before recommending the next step, helping reduce wasted spend and repeat issues.
A structured process and straightforward communication built around what the vehicle actually needs, not assumptions.
Use the checker for quick preliminary guidance. If the symptoms point to a live fault or blocked-filter risk, the next step is usually assessment.
A few simple reminders help protect the vehicle and make the next step clearer.
Prestige Performance Group in Newtownards provides diagnostic-led DPF assessment and cleaning for drivers across Northern Ireland. We do not believe every DPF warning light should be treated with a blind clean. The vehicle is checked first using fault codes, live data, pressure readings and symptom history so the correct route can be recommended.
Our DPF services cover blocked DPF filters, failed regenerations, limp mode, pressure sensor faults, soot loading, ash-related issues and repeat DPF warning lights.
A blocked DPF can often be cleaned if the filter is suitable and the root cause is found first. Soot-related blockages may respond well to on-car DPF cleaning, while higher mileage or ash-loaded filters may require a deeper off-car cleaning or refurbishment route.
This is why we recommend a DPF assessment before cleaning. Cleaning the filter without fixing the cause can lead to the fault returning.
Prestige Performance Group offers professional DPF cleaning in Newtownards for cars, vans and light commercial vehicles. We help customers from Newtownards, Bangor, Comber, Dundonald, Belfast, the Ards Peninsula and wider Northern Ireland.
If the vehicle has a DPF light, engine management light, limp mode, smoke, poor fuel economy or failed regenerations, a DPF assessment is normally the best first step. This helps confirm whether the vehicle needs on-car DPF cleaning, off-car cleaning, sensor diagnosis, AdBlue/SCR diagnosis, EGR checks or further repair work.
We investigate DPF warning lights, engine management lights, glow plug lights, limp mode, failed regeneration messages, excessive fan running, smoke, rising oil level, high soot loading and repeat pressure sensor faults.
The aim is to separate a blocked filter from the fault that caused it, so the repair path is based on evidence rather than another reset or forced regeneration.
A DPF assessment usually includes fault-code checks, live data review, pressure readings, soot and ash context where available, regeneration history and a conversation about recent driving pattern and previous repairs.
After the checks, we explain whether cleaning, refurbishment, sensor diagnosis, AdBlue/SCR investigation or another repair route is the sensible next step.
Clear answers before you commit to the next step.
Not always. Cleaning may be effective in the right case, but only if the root cause and filter condition support it.
In many cases, yes. Assessment helps provide a clearer plan and may reduce spending on the wrong route.
The current assessment time shown on this page is 1 hour.
Common causes include short journeys, failed regenerations, pressure sensor faults, glow plug faults, temperature sensor faults, EGR issues, boost leaks, injector problems and underlying engine faults.
Yes. Prestige Performance Group is based in Newtownards and helps customers from Bangor, Comber, Dundonald, Belfast, the Ards Peninsula and wider Northern Ireland.
If the vehicle is in limp mode, smoking heavily, showing oil level warnings or repeatedly failing regeneration, avoid pushing it hard and book a check. Continued driving can make a repair more expensive if the underlying fault is still active.
Bring any previous diagnostic reports, repair invoices and details of when the warning light appears. Recent work on sensors, EGR, injectors, turbo, AdBlue or oil service history can help narrow down the cause faster.
If you are unsure, use the DPF checker. If the vehicle already has warning lights, limp mode or repeat regeneration issues, book the assessment and let the diagnostic result guide the repair path.
