Vauxhall Mokka Diesel Particulate Filter DPF X (2016-2019)

The Diesel Particulate Filter (DPF) on the Vauxhall Mokka X, typically found on the 1.6 CDTI diesel engine, is an anti-pollution device located in the exhaust system between the catalytic converter and the silencer. It captures up to 99% of harmful soot particles released from diesel combustion, which are carcinogenic and polluting.

The DPF consists of a ceramic body with around 50 microscopic channels per cm² that trap soot particles while allowing exhaust gases to pass freely.

Its operation has two main phases:

• Passive filtration : Soot builds up on filter walls, increasing efficiency but also pressure, which can clog the engine and reduce power.
• Regeneration : This process clears the soot either passively (natural burning at high engine load such as highway driving) or actively through engine control, which raises exhaust temperature to burn off soot every 500–700 miles, lasting 5-15 minutes.

DPF clogging frequently occurs in urban or short-distance use, as passive regeneration requires prolonged higher speed driving. This makes the DPF a potential problem area in city driving, causing increased back pressure and engine power loss.

• Soot accumulation triggers warning lights on the dashboard.
• The vehicle may enter limp mode to protect the engine.
• Fuel consumption rises and black smoke emissions may be seen.

DPF lifespan varies based on driving habits. Regular manual regeneration with diagnostic tools is recommended to extend filter life.

To maintain your Mokka’s DPF and keep it functioning properly, several options exist:

• Professional cleaning : Injecting gases to heat the exhaust and burn soot, effective even without long motorway rides.
• DPF replacement : With guidance available for DIY replacement; compatible high-quality parts exist for Mokka and Mokka X models.
• New DPFs with integrated oxidation catalytic converters : Certified and approved for on-road use on the 1.6 CDTI (J13) engine.
• Manual regeneration : Using an OBD diagnostic tool to force the regeneration cycle and optimise filter efficiency.

Regular checking and cleaning are important especially if driving mostly in urban or short trip conditions.

Krosfou DPFs are high-performance, brand-new products made of INOX 409 stainless steel and high-quality ceramics, certified to meet or exceed original manufacturer standards with EU E24-103R approval. They come with a 3-year warranty up to 100,000 km and are designed to improve exhaust flow without sacrificing engine power.

These filters feature:

• Advanced honeycomb monolith structures with rare metals coating ensuring durability and efficiency.
• Manufacturing technology certified by TÜV SÜD, Europe’s leading automotive certification authority.
• Compliance with Euro 6 emission standards when fitted on compatible vehicles.

Krosfou provides direct factory support, installation guides, and technical assistance to guarantee optimal performance and safety.

The DPF warning light indicates the filter is becoming clogged and regeneration is needed. This can happen because of:

• Driving mostly at low speeds causing incomplete passive regeneration.
• Malfunction or sensor issues in the regeneration cycle.
• Excessive soot or ash accumulation within the filter.

When the light appears :

• Drive at sustained higher speeds (e.g., motorway) to allow passive regeneration if conditions permit.
• If warning persists, visit a garage to perform a manual regeneration using a diagnostic tool.
• Have the DPF inspected and cleaned or replaced if needed.

Ignoring the warning can lead to power loss, increased fuel consumption, and potential engine damage.

Regeneration cleans accumulated soot in the DPF by burning it off through elevated exhaust temperatures generated by the engine management system. There are two types:

• Passive regeneration : Happens naturally during long, high-speed engine operation such as highway driving.
• Active regeneration : Initiated by the engine control unit closing the EGR valve, post-injection of fuel, and turbo adjustments to increase exhaust heat, occurring approximately every 500-700 miles and lasting 5-15 minutes.

In the Mokka X, additional combustion gas injection may be used to force regeneration even on short trips where long drives are not feasible.

Yes, replacement tutorials and videos are available for Mokka and Mokka X diesel particulate filters. Compatible replacement parts designed to meet manufacturer specifications are accessible and come with installation guides.

• DPF replacement requires care to avoid damage to sensors and surrounding components.
• Professional cleaning tools and diagnostic devices are recommended for effective in situ regeneration and maintenance.
