Struggling with poor emissions performance or rising fault codes? The Diesel Oxidation Catalyst is a vital part of your after-treatment system, responsible for converting harmful gases like carbon monoxide and hydrocarbons into less toxic substances. When blocked, it can cause knock-on issues across your Diesel Particulate Filter (DPF) and (Selective Catalytic Reduction) SCR systems. That’s where we come in. At DPF Clean Team, we offer expert diesel oxidation catalyst cleaning that restores performance, extends system life and reduces emissions without the cost of replacement.
A clean DOC helps maintain smooth exhaust flow and reduce backpressure.
Properly working DOCs break down harmful gases and keep your system compliant.
DOC cleaning is more affordable than replacing the entire unit.
Prevents early wear on connected components like DPFs and SCR systems.
Once your garage confirms a DOC issue, whether that’s through emissions testing, warning lights or diagnostics we arrange fast collection. Using the same proven approach as our DPF services, we apply high-temperature treatment to dislodge carbon, then flush with air to restore flow. It doesn’t matter if the DOC is integrated with the DPF or housed separately, we’ll make sure it’s cleaned thoroughly and returned in top working condition. All units are tested before dispatch and include a 12-month warranty. Most are back with you in just 2–3 days.
DOC cleaning removes carbon, hydrocarbons and residue from the catalyst, restoring its ability to reduce harmful emissions.
