Dacia Dokker Diesel Particulate Filter DPF (2012-2020)

The Diesel Particulate Filter (DPF) on the Dacia Dokker 1.5 dCi diesel engine is an exhaust system component designed to capture fine particulate matter (soot) from the exhaust gases. It helps reduce pollutant emissions by trapping these particles, which are then periodically burned off during a process called regeneration to prevent clogging.

The DPF is mainly found on the 1.5 dCi diesel engines (codes K9K such as K9K 626), with power outputs of 75 hp (55 kW) or 90 hp. It applies to Dokker Express manufactured roughly between June 2012 and June 2015, and Dokker models with 1.5 dCi engines from November 2012 onwards. The DPF is used on variants including Dokker Break and Dokker Express and is often combined with a catalytic converter.

Common issues include the DPF clogging due to particle buildup, leading to warning lights on the dashboard. The vehicle uses sensors and control units to monitor filter status. Symptoms often indicate the need for filter regeneration or cleaning.

• DPF warning light on
• Reduced engine power or performance
• Increased fuel consumption
• Failed emissions tests

DPF regeneration can be automatic or forced (e.g., via OBD diagnostic tools). Professional cleaning or replacement may be required if the filter is heavily clogged.

DPF regeneration involves burning off soot particles accumulated in the filter. Regeneration can be passive (while driving at high engine load) or active (using post-injections of fuel to raise exhaust temperature). The process lasts around 30 minutes, during which the filter heats up to efficiently oxidize trapped particulates.

• Automatic or forced via diagnostic tools
• Monitoring by sensors and engine control units
• Temperature rises to about 88% of maximum before reducing
• Vehicle may require sustained driving at higher RPM for passive regeneration

Failing to perform regeneration can shorten DPF life and cause vehicle issues.

Key OE reference numbers for DPFs compatible with the Dacia Dokker 1.5 dCi include:

• 200107822R
• 200103436R
• 200105495R
• 200106590R
• 208026180R
• 208025559R

Typical filter length is about 1050 mm (for example, ref. JMJ 1207).

Proper maintenance of the DPF includes:

• Using high-quality diesel fuel
• Driving regularly at higher engine speeds to allow passive regeneration
• Monitoring dashboard warning lights and addressing faults promptly
• Performing professional cleaning if warning lights persist

Consult a diagnostic specialist or garage if faults continue after regeneration attempts.

Original and high-quality new DPFs are available from specialized manufacturers producing stainless steel DPFs certified with a 3-year warranty. These products comply with manufacturer specifications and European emission standards. Krosfou, for example, offers such DPFs with guaranteed performance and durability.

• New, original parts (not refurbished)
• Manufactured with advanced ceramic monoliths
• Certified by TUV SÜD Automotive GmbH
• 3 years warranty limited to 100,000 km use

Always ensure compatibility by providing your Vehicle Identification Number (VIN) when ordering.

If the DPF warning light remains illuminated after attempted regeneration, consider the following steps:

• Have a professional diagnostic check to clear fault codes and verify sensor functionality
• Request professional DPF cleaning (decoking) to remove stubborn soot and ash accumulation
• If the filter is permanently clogged, replacement with an original DPF is recommended
• Always use recommended maintenance and driving routines to prevent early clogging

Ignoring persistent DPF faults can lead to engine performance loss and increased emissions.
