DPF Cleaning – Moordown, Bournemouth

A diesel particulate filter, or DPF, traps soot from your exhaust to reduce harmful emissions. Over time, it can become partially blocked, particularly on cars used mainly for short journeys, and this is where cleaning or regeneration becomes necessary.

Signs your DPF may be blocked

A blocked or partially blocked DPF often shows itself through:

A dashboard warning light specifically related to the DPF
Reduced engine power or a car that feels sluggish
Increased fuel consumption
Difficulty starting or rough idling
A burning smell during a regeneration cycle

If you’re seeing any of these, it’s worth having the DPF checked before the problem worsens.

Why DPFs become blocked

DPFs are designed to burn off trapped soot periodically through a process called regeneration, which usually happens automatically during sustained driving at higher speeds. Cars used mainly for short trips around Bournemouth or similar urban driving often don’t reach the conditions needed for this to happen naturally, allowing soot to build up over time.

Off-vehicle cleaning versus replacement

At FitnFix Auto, we use an off-vehicle DPF cleaning machine, which allows us to remove the filter and clean it thoroughly rather than relying on a forced regeneration alone. This is often a more effective and considerably cheaper option than replacing the filter entirely, provided the DPF hasn’t been damaged.

When replacement is the only option

If a DPF has cracked, melted internally, or suffered physical damage, cleaning won’t resolve the issue and replacement becomes necessary. We’ll always check the condition of the filter first before recommending either option.

FitnFix Auto is proud to be accredited by the IGA and Trust My Garage, and recognised by HEVRA, SERMI, and Trading Standards, giving you independent assurance that we work to genuine industry standards.
