Modern diesel vehicles rely on advanced emission control systems to meet strict environmental standards. One small but often overlooked component in this system is the particulate additive pouch, identified by OEM reference 9678101680. Understanding how this part works can help prevent costly repairs and extend engine life.
1. What Is 9678101680 and What Does It Do?
OEM reference 9678101680 refers to a particulate additive pouch used in PSA diesel vehicles equipped with a DPF (Diesel Particulate Filter) system.
The additive is introduced into the combustion process to lower the temperature required to burn soot inside the DPF. This allows regeneration to occur efficiently, even during normal driving conditions.
Without this additive support, soot accumulates faster, regeneration becomes incomplete and exhaust flow is restricted.
2. How the DPF Regeneration Process Depends on the Additive
DPF regeneration works by periodically burning off soot particles trapped in the filter. However, standard exhaust temperatures are often not high enough, particularly during short or urban journeys.
The particulate additive:
- Reduces soot ignition temperature
- Allows more frequent and complete regeneration
- Helps keep the DPF clear during stop-start driving
When the additive system is depleted or faulty, regeneration efficiency drops, leading to warning lights, reduced engine performance and increased fuel consumption.
3. Why This Part Is Critical for Engine Longevity
A malfunctioning or empty additive pouch affects more than emissions. Restricted exhaust flow increases back-pressure, which places additional strain on key engine components.
- Turbocharger
- EGR valve
- Fuel injectors
Maintaining correct DPF operation helps protect these components and supports long-term engine reliability.
4. Emission Standards and Compliance Risks
Diesel vehicles fitted with DPF systems are designed to meet strict emission regulations. If the additive system is not functioning correctly:
- Regeneration frequency decreases
- Soot emissions increase
- MOT and inspection failures become more likely
In many cases, replacing the correct additive pouch restores factory-level emission performance without the need for expensive DPF replacement.
5. Compatibility Matters More Than You Think
One of the most common mistakes is assuming all particulate additive pouches are interchangeable. In reality, multiple additive systems can be fitted to the same vehicle model.
Using the wrong additive may prevent correct regeneration and lead to further system faults. Always confirm the OEM reference number from the existing unit before purchasing a replacement.

Frequently Asked Questions
What is the particulate additive pouch 9678101680 used for?
The particulate additive pouch with OEM reference 9678101680 is used in PSA diesel vehicles to support DPF regeneration by lowering the temperature required to burn soot inside the diesel particulate filter.
What happens if the particulate additive pouch is empty or faulty?
If the additive pouch is depleted or faulty, DPF regeneration becomes inefficient. This can lead to soot build-up, dashboard warning messages and reduced engine performance.
Can a faulty additive system damage the engine?
Yes. Poor DPF regeneration increases exhaust back-pressure, which can strain the turbocharger, contaminate the EGR valve and accelerate injector wear over time.
Are all particulate additive pouches interchangeable?
No. Different additive systems can be fitted even within the same vehicle model. Always match the OEM reference number before purchasing a replacement.
