Volkswagen Touareg Diesel Particulate Filter DPF

A diesel particulate filter (DPF) is a key component of the exhaust system in a modern diesel engine. Its main function is to capture and store soot and fine particulate matter that would otherwise be emitted into the air. It uses cordierite or silicon carbide material to filter carbon from exhaust gas. Found in most TDI models, the DPF helps vehicles meet Euro 4, Euro 5, and EEC emission standards, keeping the air cleaner while maintaining proper engine performance.

That little warning light usually means your DPF is reaching its storage limit. Common causes include:

• Short trips where the automatic regeneration can't complete
• Faulty sensors or malfunctioning EGR valves
• Low fuel levels disrupting the regen cycle
• Long-term buildup of ash despite frequent regeneration

Take action early to avoid further damage to your catalytic converter or turbocharger.

Several cleaning methods are available based on the condition of your filter:

• Passive regeneration: Just take a 20-30 min drive at motorway speed to trigger heat-based cleaning
• Active regeneration: Car injects fuel to raise exhaust temperature and initiate the process
• Forced regeneration: Performed by a garage using diagnostic tools
• DPF cleaners: Foam or chemical products sprayed into the unit to break down deposits

Proper cleaning routines extend DPF life and help you save money over time.

Watch for these signs:

• The DPF light stays on
• Sluggish acceleration or reduced power
• Poor fuel economy
• Engine running rough or entering "limp mode"
• OBD codes indicating back pressure or sensor issues

These all point to an overloaded DPF in need of attention or replacement.

At Krosfou, our product list includes DPFs starting at around £270, with top-tier models reaching £460. Every kit comes with essential mounting hardware, pressure pipe adapters, and gaskets. Whether you're looking for a basic fix or a premium brand, we offer transparent price tiers, available online for immediate sale.

Absolutely. Even with active regeneration cycles, ash buildup will eventually reduce filter efficiency. If you're seeing frequent warnings, struggling with miles per gallon, or noticing pressure faults, the DPF may need to be replaced. A pre-emptive replacement can prevent more serious damage.

You can shop DPFs directly on Krosfou.co.uk. We specialize in direct-fit DPF units for:

• Volkswagen Touareg (CASA, CASB, CASC engines)
• Audi Q7 VW Touareg shared platforms
• Porsche Cayenne diesel variants

Every item is fully detailed with specs like weight, material, and standard compliance. We also collect real-time inventory to ensure what's listed is in stock.

Our Touareg range includes options for:

• 2.5 TDI (2006–2010)
• 3.0 TDI (7L7 chassis)
• CR7 models with air suspension and enhanced cooling

Choose from top brands like BM, AMS, and IKIO, or select our own high-quality line. All options include detailed installation articles and come with fitting kits.

Expect a well-maintained filter to last between 80,000 and 120,000 miles, depending on your driving style, fuel quality, and whether regeneration completes regularly. City drivers or those with heavy loads might need to replace the unit sooner. A proactive service schedule can help you extend its life.

It's not recommended. Short-term driving is okay, but over time you risk body damage to the exhaust, higher repair costs, or triggering additional failures. Don't ignore the sign – take action to inspect or service the unit.

Yes. A clogged or inefficient DPF restricts exhaust gas flow, limiting power and causing erratic shifts in automatic gearboxes. You might also hear strange sounds or experience a bad throttle response. Addressing this early helps your suspension, turbo, and drivetrain work optimally.

Euro 4: Basic particulate filtering, suitable for older vehicles. Often cordierite-based.

Euro 5: Improved emission control, better heat resistance, and enhanced soot collection.

Always verify with your engine code and consult with a Krosfou expert before placing your order.

Yes – especially for filters in moderate condition. Foam-based cleaners assist with passive and active regen by loosening up deposits. For heavily clogged filters, replacement might be required instead.

Our kits generally include:

• Gaskets
• Screws and bolts
• Sensor mounting hardware
• Pipe clamps
• Instructions with step-by-step details

Always verify the compatibility before beginning installation.

Common causes include:

• Using the wrong engine oil
• Too many low-speed trips
• Pre-existing issues with the turbo or EGR
• Not completing regeneration cycles

Spending a bit of time on prevention can help you save significantly on repairs.

If you have a lift and the right tools, yes. But it's considered a technical installation, and we suggest using a trained technician. Mistakes during fitting can cause exhaust leaks, sensor malfunctions, or even void warranties. Always view your workshop manual for exact steps.

Use a diagnostic scanner to:

• Monitor pressure values
• View completed and pending regen cycles
• Detect sensor or OBD error codes

If numbers are off or faults keep appearing, your DPF may be nearing the end of its service life.
