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

The Diesel Particulate Filter (DPF) on the Opel Mokka X is a key component of the exhaust system designed to reduce harmful soot emissions from diesel engines, especially in models like the 1.6 CDTI and 1.7 CDTI. Positioned after the catalytic converter and before the silencer, the DPF traps up to 99% of soot particles using a ceramic structure with microscopic channels.

The DPF functions in two main phases: filtration and regeneration. During filtration, fine soot accumulates inside the filter, and if unchecked, this can lead to increased backpressure and reduced engine performance. Regeneration is the process of burning off this soot, which occurs either passively at high speeds or actively through controlled engine management to maintain efficiency and prolong filter life.

Typical symptoms of a defective or clogged DPF on the Opel Mokka X 1.6 CDTI and 1.7 CDTI include :

• Increased fuel consumption
• Loss of engine power
• Illumination of the "Check Engine" or DPF warning light on the dashboard

If these signs appear, it may indicate the DPF needs cleaning or replacement to avoid further engine performance issues.

To maintain the DPF efficiently and restore its filtering capacity, the following methods are recommended :

• Driving at a sustained speed of 65-80 km/h for 20-24 minutes to reach the temperature needed for passive regeneration, which burns accumulated soot
• Using diagnostic tools like VCDS to force active regeneration when necessary
• Applying specialized DPF cleaning products such as DPF Cleaner, which can unblock the filter without replacement

Note that the DPF accumulates a maximum ash weight of around 60 g before it requires replacement.

The DPFs for the Opel Mokka X vary by engine type :

• For the 1.6 CDTI 136 HP (D 16 DTH): Capacity 400 ml, material Cordierite or Silicon Carbide, weight 6.7 kg (Cordierite) or 7.6 kg (Silicon Carbide), compliant with Euro 6 and OBD diagnostics, produced since 06/2015
• For the 1.7 CDTI 131 HP (A 17 DTS): Capacity 450 ml, compatible with DPF Cleaner products

Part numbers and compatibility references include models like the Mokka X 1.6 CDTI 4WD (J13) with reference DPF-G8729 and stock availability.

The DPF warning light indicates a problem with the diesel particulate filter :

• The filter is becoming clogged with soot
• Excessive backpressure is affecting engine performance
• Possible sensor faults or regeneration failures

If the light comes on, it is recommended to perform a regeneration drive and if the warning persists, get professional DPF diagnostics and possibly cleaning or replacement to avoid damage.

The DPF regeneration system on the Opel Mokka X works automatically during normal driving to burn accumulated soot particles :

• Passive regeneration occurs at sustained high speeds where exhaust temperature is sufficient to burn soot
• Active regeneration is initiated by the engine management system when differential pressure sensors detect clogging, using additional fuel injection to raise temperature
• A normal differential pressure at idle is around 20-30 mbar; pressure above 60 mbar signals severe clogging and need for regeneration or cleaning

Regular regeneration is essential to maintain DPF efficiency and vehicle performance.

While some maintenance such as regeneration drives can be done by the vehicle owner, proper DPF cleaning, diagnostics, and replacement require specialized equipment and expertise. It is recommended to have DPF replacement or thorough cleaning done by qualified professionals to ensure correct installation, sensor calibration, and compliance with emissions regulations.

• Use only approved DPF cleaning products
• Replacement must include necessary gaskets, sensors, and follow manufacturer instructions
• Improper handling or negligent use can void warranties
