Expert Citroen DPF cleaning
The diesel particulate filter on your Citroen — fitted with the HDi diesel engine — captures soot from the exhaust and burns it off during regeneration. Citroen HDi engines use an additive (Eolys) system that still clogs the DPF over time. When the filter blocks, you'll often see a warning light, lose power, use more fuel, or drop into limp mode.
Rather than replacing an expensive factory part, our off-car cleaning process removes the trapped soot and ash and restores your Citroen DPF to near-original flow — for a fraction of the cost.
Common signs on your Citroen
Citroen's HDi engines inject a fuel additive (Eolys) to help regeneration, but the additive doesn't stop ash building up — it only makes the soot easier to burn. Over years of driving, the filter still needs a physical clean.
A blocked filter on this engine family can trigger fault codes such as P2463, P244A — both indicate the DPF needs attention rather than a new part.
