DPF warning light on, reduced power, or repeated failed regenerations? At Oldfields Garage, we offer professional DPF cleaning in Leominster, backed by proper diagnostics, clear explanations and a process designed to fix the cause, not just mask the symptoms.
Many DPF issues can be resolved without replacement, but only when the system is assessed correctly from the start. That is exactly how we work.
Fixed price DPF assessment. Always the starting point.
Every vehicle booked in with us for a DPF issue begins with a fixed price DPF assessment.
We do this because DPF faults are rarely just about the filter itself. Sensors, driving patterns, engine faults and exhaust temperatures all play a part. Jumping straight to cleaning without understanding the root cause often leads to repeat problems and wasted money.
Our assessment includes:
-
Full diagnostic fault code scan
-
World leading DPF Doctor Assessment
-
Live data analysis of DPF pressures and temperatures
-
Checking regeneration history and soot loading
Once complete, we explain the findings clearly and talk through the best next step. No work goes ahead without your approval.
What a DPF does and why problems occur
A Diesel Particulate Filter traps soot from the exhaust to reduce emissions. Under the right conditions, this soot is burned off during regeneration.
Modern driving patterns are the biggest cause of problems. Short journeys, stop-start use and unresolved engine faults prevent the DPF from reaching the temperatures needed to clean itself. Over time, this leads to blockages and warning lights.
Common signs of DPF trouble
-
DPF or engine management warning light
-
Loss of power or limp mode
-
Poor fuel economy
-
Frequent regeneration attempts
-
MOT emissions failures
If left untreated, a blocked DPF can trigger further faults and increase repair costs.
DPF cleaning in Leominster, the right way at Oldfields Garage
We are part of the DPF Doctor network, giving us access to world-leading DPF training, technical support and proven cleaning methods. This allows us to diagnose and clean DPF systems properly, rather than relying on guesswork or shortcuts.
One important point to be clear about: We never carry out forced regenerations.
Forced regenerations can hide underlying faults, overheat components and often result in repeat failures. Instead, we use controlled, evidence-based cleaning methods suited to the condition of the filter.
Depending on the assessment results, we may recommend:
-
In-situ DPF cleaning in Leominster, carried out on the vehicle
-
DPF removal and deep cleaning using our in-house Carbon Clean DCS Pro DPF cleaning machine
Our equipment allows us to clean internally and thoroughly, restoring flow and reducing soot and ash levels where cleaning is appropriate.
After cleaning, we recheck live data to confirm the DPF is functioning correctly and provide advice to help prevent recurrence.
