Ford Galaxy Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) in Ford Galaxy vehicles traps soot particles in the exhaust gases to reduce pollution. It requires regular regeneration, a process where the trapped soot is burned off at high temperatures (around 600°C), leaving only residual ash. This regen process is triggered automatically by specific engine settings that inject fuel late in the cycle to heat the exhaust, assisted by a lean diesel/oxygen-rich mixture. The DPF is integrated into the exhaust line and monitored by differential pressure sensors to ensure proper function and timely regeneration.

DPF systems are commonly found in Ford Galaxy models from 2006 onwards to comply with Euro 4/5/6 emissions standards. Notable models include:

• Ford Galaxy 2.0 TDCi 115 hp – standard diesel DPF, prone to soot clogging.
• Ford Galaxy 2.2 TDCi (engine KNWA, 11/2010-04/2012, Euro 5) – combined DPF and catalytic converter with new spare parts available.
• Ford Galaxy 1.5 EcoBoost 160 hp – petrol version which may have a Gasoline Particulate Filter (GPF).

Krosfou offers brand-new, high-quality DPFs manufactured in Europe, compliant with OEM and regulatory standards, backed by a 3-year warranty.

Common signs of DPF issues include:

• DPF warning light on dashboard, indicating soot and ash build-up.
• Loss of engine power or performance due to filter blockage.
• Increased fuel consumption from failed or incomplete regeneration cycles.
• Frequent engine warning lights triggered by regeneration failures.

These symptoms may worsen if the DPF cannot complete regeneration, particularly in stop-start or city driving conditions where the engine does not reach optimal running temperature.

Ford Galaxy DPF maintenance involves several methods:

• Passive regeneration: driving at sustained higher speeds and engine RPMs (typically on highways) to naturally burn off soot.
• Active regeneration: the engine injects additional fuel to raise exhaust temperature and initiate soot burn-off when necessary.
• Chemical cleaning: professional garages can inject cleaning agents upstream of the DPF to dissolve soot and ash deposits.
• Regular diagnostics: checking differential pressure sensors via OBD to monitor filter condition.

For stubborn clogging, professional cleaning or replacement may be required. Avoid attempts to remove or bypass the DPF, as this is illegal and may fail MOT tests.

Removing or deleting the DPF is illegal in the UK and most European countries. Vehicles without a functioning DPF will fail MOT emissions testing and will not comply with Euro emissions standards. Some shops may claim to remove the DPF and still pass MOT, but this can lead to fines, insurance invalidation, and environmental penalties. It is strongly recommended to maintain, clean, or professionally replace the DPF to keep your vehicle compliant and environmentally friendly.

DPF regeneration typically lasts between 10 to 20 minutes depending on vehicle model and soot load. During regeneration, the exhaust temperature rises to around 600°C to burn accumulated soot.

Optimal driving conditions for regeneration are:

• Continuous driving at speeds above 40-50 mph (65-80 km/h).
• Engine running in a higher RPM range and gear for steady heat generation.
• Avoiding short trips, city stop-start driving, or idling, which prevent full regeneration.

Using the vehicle on motorways or open roads at consistent speeds helps ensure the DPF runs in proper regen mode.

Replacing a DPF on a Ford Galaxy generally takes about 2 hours or a bit more depending on the model and workshop efficiency. For example, replacing a DPF on the 2.2 TDCi model is estimated around 2 hours of labour time. This includes removal of the old filter, installation of the new high-quality DPF, and system checks. Krosfou supplies new original quality DPF parts with a 3-year warranty, ensuring reliable performance.

Yes, for service, cleaning or replacement of your Ford Galaxy DPF it is recommended to:

• Visit a professional garage with experience in DPF diagnosis and cleaning.
• Request a full diagnostic including differential pressure sensor check.
• Ask for a detailed quote including parts, labour time (usually around 2 hours), and any chemical cleaning service.
• Consider using proven Krosfou brand new replacement DPF parts known for quality and durability.

Proper maintenance and timely intervention help extend your vehicle’s DPF lifespan and reduce the risk of costly repairs.
