Mercedes Citan Diesel Particulate Filter DPF (2012-2021)

The Diesel Particulate Filter (DPF) in Mercedes Citan vehicles (especially diesel models like 109 CDI, 111 CDI with chassis code W415) is an essential exhaust component designed to trap fine soot particles produced by diesel engines. It ensures compliance with Euro 5 and Euro 6 emissions standards by reducing particulate pollution and protecting the environment. This filter is typically found on 1.5L diesel engines (OM607.951) manufactured since June 2013.

The following Mercedes Citan diesel models are fitted with a DPF as standard:

• Mercedes Citan 109 CDI 1.5 (Tourer/Break, code 415-703), Euro 6 compliant, produced from 2013 onward
• Mercedes Citan 111 CDI (W415), Euro 5 compliant, supplied with mounting hardware
• Other variants such as Citan Tourer Lang 108 CDI 75 cv (2012 model year)

These DPFs have both passive and active regeneration systems integrated to burn off accumulated soot.

To maintain optimal DPF function and avoid costly replacement, you can perform cleaning using these methods:

• Drive the vehicle consistently at 60-80 km/h for about 25-30 minutes to trigger passive regeneration and burn off soot accumulation.
• Professional cleaning products that inject a cleaning agent and flush through the filter without dismantling it, using around 12 litres of cleaning fluid. This restores filter efficiency economically.

These methods help prevent warning lights and error codes triggered by soot buildup, common in urban driving or short trips.

Symptoms indicating issues with the DPF include:

• Loss of engine power or reduced performance
• Check engine light or DPF warning light illuminated on the dashboard
• Failed or incomplete forced regeneration attempts

These signs are often caused by soot clogging the filter, especially from frequent low-speed or city driving without adequate DPF regeneration.

Replacing the DPF involves detailed mechanical steps, including:

• Dismantling sections of the exhaust system to access the DPF
• Removing the old particulate filter
• Installing the new DPF and reassembling the exhaust

Illustrated manuals and video tutorials are available for all Mercedes Citan models to guide through the replacement process safely and correctly.

The price for a new DPF for Mercedes Citan varies depending on model and supplier. Generally:

• The Mercedes Citan 109 CDI 1.5 Euro 6 DPF is available as a new part with stock availability.
• The 111 CDI W415 Euro 5 DPF may also be purchased with mounting options.

Prices usually range between €500 and €1500, but exact costs should be confirmed by entering your vehicle's VIN for compatibility and pricing on sales platforms.

Injecting cleaning agents into the DPF and purging from the top is a professional cleaning method used by some specialists to restore filter efficiency without removal. However, it is recommended to:

• Use only approved cleaning products designed specifically for DPF cleaning
• Seek expert advice or professional service to avoid damage
• Confirm this method's compatibility with your Mercedes Citan's DPF model

This method helps reduce soot blockage and prevent DPF-related faults.
