Volkswagen Caravelle Diesel Particulate Filter DPF T4 (1990-2004)

The Diesel Particulate Filter (DPF) is a key component in the exhaust system of diesel vehicles such as the Volkswagen Caravelle T4. It captures fine soot particles from the exhaust gases, reducing harmful emissions and helping the vehicle meet Euro 4 or Euro 5 anti-pollution standards. Without a properly functioning DPF, diesel vehicles produce more particulate matter that harms air quality and engine performance.

DPF filters for Volkswagen Caravelle T4 fit various chassis and engine types produced between 1989 and 2003, including but not limited to these combinations:

• Chassis: 70A, 70H, 7DA, 7DH for vans; 70XB, 70XC, 7DB, 7DW for buses and coaches
• Engines: 2.5 TDI (88 hp AJT, 102 hp AYC), 2.4 D (75-78 hp), plus some BMP/BLS engine codes

New DPF units in corderite ceramic are available, fully compliant with Euro 4 and Euro 5 standards and designed for vehicles equipped with onboard diagnostic systems (OBD).

Typical DPFs for the Caravelle T4 vary in size and weight depending on the engine and vehicle type:

• Length ranges from 350 mm up to 1750 mm
• Weight ranges from approximately 5.4 kg to 10.6 kg
• Materials used: high-quality corderite ceramic monoliths in stainless steel housings
• Conform to Euro 4 or Euro 5 emission standards

These filters are engineered for durability and efficient particle capture during diesel exhaust regeneration cycles.

To keep your DPF functional and avoid expensive replacements, various cleaning products are available specifically for diesel particulate filters. These include sprays and liquids designed to remove ash and soot deposits accumulated inside the DPF over time.

• Products come in sprays or liquid forms, generally from 400 ml to 1 litre containers
• Examples of well-regarded cleaning products: PETEC, Valvoline, CARTECHNIC, MANNOL, WYNN'S, among others
• These additives are used either during driving or by flushing the filter through specialized methods

Regular use according to manufacturer guidelines helps maintain exhaust flow and optimal sensor operation.

Common symptoms that your vehicle’s DPF may be clogged or malfunctioning include:

• DPF warning light or other error indicator lights illuminating on the dashboard
• Reduced engine power or difficulty driving
• Unusual exhaust smoke or smell
• Increased fuel consumption
• Problems clearing fault codes without proper regeneration

Early diagnosis and cleaning or replacement is crucial to avoiding permanent damage and costly repairs.

DPF regeneration is a process that burns off trapped soot to clean the filter and restore exhaust flow. There are two main types:

• Passive regeneration happens naturally during extended drives at highway speeds when exhaust temperature is sufficiently high.
• Active regeneration is initiated by the vehicle’s ECU, injecting extra fuel to increase exhaust temperature when needed, usually indicated by vehicle alerts to continue driving until completion.

It is important to follow manufacturer recommendations and avoid skipping regeneration cycles to maintain DPF health.
