DPF Cleaning in Manchester

Common signs your DPF is blocked

You may need a DPF service if you notice:

• DPF / engine management light on the dashboard

• Loss of power or limp mode

• Increased fuel consumption

• Frequent regeneration attempts (fan running, hot smell)

• Smoke under load (in some cases)

• Warning messages like “DPF Blocked”

Our DPF Services

1) DPF Diagnostic & Fault Code Check

We scan the vehicle with professional diagnostic equipment and assess:

• DPF soot load / regeneration status

• Differential pressure readings

• Exhaust temperature sensor data

• Related faults (EGR, boost, injectors, sensors)

This step is important because DPF blockage is often a symptom, not the root cause.

2) On-Car DPF Chemical Cleaning (Soot & Light Ash)

A specialist DPF cleaning solution is applied to help break down soot and loosen deposits. This can:

• Reduce back pressure

• Improve exhaust flow

• Increase the chance of successful regeneration

• Restore drivability on mildly to moderately blocked DPFs

3) Forced DPF Regeneration

If safe to do so, we carry out a controlled forced regeneration using diagnostic equipment. This burns off soot at high exhaust temperatures and is often used when normal driving regeneration can’t complete.

4) Off-Car DPF Deep Cleaning (Severe Blockage)

For heavily blocked filters, the DPF may need removal and deep cleaning to remove stubborn contamination and higher ash loading (where applicable). We’ll advise honestly if removal is required.

5) DPF Sensor Checks (Pressure & Temperature)

Faulty sensors can cause incorrect DPF warnings and failed regenerations. We test and replace (if needed):

• Differential pressure sensors / hoses

• Exhaust gas temperature (EGT) sensors

6) DPF Reset / Adaptations (After Cleaning or Replacement)

Where appropriate, we reset relevant DPF values only after physical cleaning/regeneration or replacement, so the ECU can monitor soot loading accurately.

What causes DPF problems?

DPF issues are common in vehicles used for:

• Short journeys and stop-start driving

• Low-speed city driving

• Frequent cold starts

• Poor servicing (wrong oil spec can increase ash)

• Underlying faults (EGR issues, boost leaks, injector faults)

We don’t just clear lights—we aim to fix the cause to reduce repeat blockages.

How long does DPF cleaning take?

• Diagnostics: 20–45 minutes

• On-car cleaning + regen: typically 1–2 hours

• Off-car cleaning: varies depending on vehicle and access

We’ll give you a realistic plan after initial checks.

FAQs

What is DPF?

DPF stands for Diesel Particulate Filter, which traps soot from exhaust.

How often clean DPF?

Cleaning depends on driving habits, but typically every 80,000 to 120,000 miles.

Signs of blocked DPF?

Warning lights, reduced engine power, increased fuel consumption, and unusual exhaust smoke.

Is cleaning safe?

Yes, we use proven, safe methods that protect your vehicle’s components.

How long does cleaning take?

Most cleanings are completed within a few hours to minimise your downtime.

Can cleaning prevent costly repairs?

Absolutely, regular cleaning helps avoid damage and keeps your vehicle running efficiently.

Can you just reset the DPF light?

We only reset DPF values after the DPF has been properly cleaned/regenerated or replaced. Resetting without fixing the blockage can lead to repeat faults and potential damage.

Is forced regeneration safe?

Forced regeneration can be safe when the vehicle meets the conditions and underlying faults are addressed. We check sensor readings and fault codes first.

Will DPF cleaning remove ash?

Cleaning can remove soot and may reduce some deposits, but heavy ash loading may require off-car deep cleaning or replacement depending on condition.

How can I prevent DPF problems?

Regular servicing with the correct oil, occasional longer drives (where possible), and fixing EGR/injector/boost faults early helps reduce DPF issues.
