Collection: EGR and DPF cleaning

EGR and DPF cleaning – products for the intake system and particulate filter

The EGR valve and diesel particulate filter (DPF) operate under demanding conditions. Soot deposits and contamination can affect their performance, although fault symptoms often have more than one cause. This category includes EGR cleaning products, agents intended for DPF maintenance, and fuel additives that support specific processes as described by their manufacturers.

EGR cleaner versus DPF cleaner – what is the difference?

Products for the EGR valve and intake system are designed for specific surfaces and application methods. DPF products may be cleaners applied according to a workshop procedure or additives dosed into the fuel. They are not interchangeable. Check whether a product is suitable for the engine type, component, and intended application.

Can a chemical product remove the cause of a clogged DPF?

Not necessarily. Excessive soot can be caused by faulty injectors, EGR or sensor problems, turbocharger faults, or frequent short trips. A cleaning agent is not a substitute for diagnosis and cannot repair a damaged filter substrate. It is also important to distinguish soot, which can be burned off during regeneration, from ash that accumulates over prolonged use.

How do you choose the right product?

• Identify whether you need to clean the EGR valve, intake system, or DPF.
• Check the required application procedure and any tools needed.
• Follow the vehicle and product manufacturers' instructions and safety precautions.
• If fault codes or loss of power occur, consider diagnosis first.
