Hyundai Sonata Diesel Particulate Filter DPF 6 (Vi) (2006-2014)

The Diesel Particulate Filter (DPF) on the Hyundai Sonata 6, especially fitted on diesel engines such as the 2.0 CRDi (D4EA) with 140 hp, is an essential emission control device that traps up to 99% of soot particles from exhaust gases. Installed after the catalytic converter and before the silencer, the ceramic honeycomb structure captures harmful particulate matter to reduce pollution.

The DPF works by filtering exhaust gases through alternate blocked channels lined with porous walls trapping soot particles. Over time, the soot builds up and must be burned off in a process called regeneration. On the Hyundai Sonata diesel, this happens actively through the engine management system, which increases exhaust temperature via EGR valve, post-injection, and turbo boost, often aided by a cerine additive that lowers the combustion temperature threshold.

Common symptoms of a clogged or failing DPF include :

• DPF warning light illuminated on the dashboard
• Loss of engine power or performance
• Black smoke or excessive soot emission from the exhaust
• High backpressure causing engine issues

If you notice any of these symptoms, it is advisable to have your car diagnosed with an OBD tool by a qualified garage.

DPF maintenance can be done without disassembly through :

• Adding cerine-based additives or FAP cleaners to fuel tanks to help dissolve soot
• Forcing active regeneration by driving for 20-30 minutes at over 3000 rpm on highways
• Professional manual regeneration using diagnostic tools

Regular dynamic driving and avoiding short trips can prolong DPF life and prevent clogging.

Replacement DPF parts for Hyundai Sonata 6 diesel models include original quality filters compatible with 2.0 CRDi engines. Indicative prices range from €400 upwards depending on the model and supplier. Installation should be performed by professionals due to the complexity of the operation. Remember, the removal of a DPF is illegal and subject to penalties.

• Example part code: HY6023T - Original DPF for Hyundai Sonata, approx. 6 kg
• Available via specialist exhaust and parts sellers with warranty and delivery options

Always opt for certified high-quality parts to ensure optimal vehicle performance and compliance with emissions legislation.

While both are part of the exhaust emission control system, the catalytic converter and DPF have different roles :

• The catalytic converter reduces harmful gases like CO, NOx, and hydrocarbons.
• The DPF specifically traps and burns particulate soot from diesel exhaust.

The DPF periodically reaches high temperatures during regeneration to burn off soot which is a distinct process from catalytic conversion. Hence, they complement each other but do not replace one another.

High-quality, original manufacturer-standard DPFs for Hyundai Sonata 6 diesel models are available direct from specialized suppliers. They are certified by TÜV Sud with 3-year warranty, manufactured in stainless steel with premium ceramic monoliths for durability and performance.

• Options include free shipping and return policies within certain conditions
• Professional customer support and technical assistance available
• Fast delivery options in the UK and Europe

Make sure to verify the part compatibility with your Sonata model and engine variant before purchase.

If you have DPF issues or queries, consider the following :

• Consult a qualified garage equipped with OBD diagnostic tools for precise analysis
• Use recommended additives and follow manufacturer guidelines for maintenance
• Contact your parts supplier or manufacturer for technical support and verified spare parts
• Join forums or communities focused on Hyundai diesel models for user tips and advice

Proper diagnosis and using certified high-quality parts ensure the longevity and performance of your vehicle’s emission control system.

Protect your car, environment, and comply with emission standards by maintaining your Hyundai Sonata DPF carefully.
