Expert Subaru DPF cleaning
The diesel particulate filter on your Subaru — fitted with the EE20 boxer diesel engine — captures soot from the exhaust and burns it off during regeneration. Subaru boxer diesel DPFs respond well to a professional off-car clean. 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 Subaru DPF to near-original flow — for a fraction of the cost.
Common signs on your Subaru
Subaru's EE20 is the only horizontally-opposed 'boxer' diesel ever fitted to a mainstream car, and its unusual exhaust layout means the DPF benefits particularly well from a full off-car strip and clean rather than an in-situ flush.
A blocked filter on this engine family can trigger fault codes such as P244A, P2463 — both indicate the DPF needs attention rather than a new part.
