06 / Emissions systems
Volvo DPF, EGR and AdBlue diagnostics
An emissions warning can come from the system itself or from a sensor, wiring or related engine fault. We investigate the cause and discuss repair options that keep the emissions system working.
DPF warnings and regeneration faults
We assess available pressure, temperature and filter-load readings alongside the fault history. A regeneration procedure may be appropriate on a supported vehicle once the cause and prerequisites have been checked. Some vehicles need further repair or filter cleaning or replacement.
EGR and related engine symptoms
EGR flow and position faults can overlap with air-path or sensor issues. We check the available readings and relevant wiring or mechanical conditions to help narrow down the cause.
AdBlue and SCR warnings
Tell us the exact dashboard wording, particularly if it shows a restart countdown. We can investigate supported SCR dosing, level, quality or sensor faults and advise on next steps based on the findings.
Frequently asked questions
Before you book.
Does a DPF warning mean I need a new filter?
The cause could involve the filter, a pressure sensor, a hose or a fault that prevents regeneration. Testing helps determine which repair is appropriate.
What should I send before the visit?
Share the engine, model year, exact warning, any recent repairs and whether there is a countdown or the car has reduced power.
