DPF EGR CAT Services – Restore Clean Performance

Your emissions system is frequently the first thing people check when the power goes out and smoke fills your tailpipe. Catalytic converters (CATs), exhaust gas recirculation valves (EGR), and diesel particulate filters (DPF) are essential for both performance and compliance. We carefully and precisely inspect, service, and replace these parts as needed.

How DPF, EGR, and CAT Faults Are Diagnosed

These are not plug-and-play setups. A mix of hardware and software problems often causes faults such as clogged filters, jammed valves, faulty pressure sensors, or incorrect oil specs. We do extensive diagnostics utilising modern scan technologies and real-time data monitoring to find the problem before suggesting a remedy.

• Live DPF soot/ash readings and number of regeneration attempts
• EGR valve flow and temperature testing
• Catalyst efficiency and downstream O2 sensor feedback B1/B2
• Pressure sensor checks and exhaust backpressure readings

When Cleaning Works and When It Doesn’t

Cleaning is a great option when the system is still structurally sound. We offer on-car and off-car cleaning for DPFs, full flush and ultrasonic methods for EGRs, and catalytic converter flow testing. But we won’t sugarcoat it: some systems are too far gone. Our job is to give you a clear breakdown of costs, outcomes, and long-term benefits.

Symptoms That Signal Emissions System Failure

• Loss of power or turbo lag
• Frequent limp mode triggers
• Engine warning lights for emissions or sensors
• Unusual fuel consumption or strong diesel smell
• Failed WOF due to emissions-related faults

DPF Regeneration: Passive, Active, and Manual

Not every DPF needs to be removed or replaced. Sometimes a proper regeneration is all it takes to restore airflow. We perform manual regenerations and guide drivers on how to trigger successful passive regen cycles. To be effective, several conditions must align fuel level, coolant temp, sensor health and we make sure they do.

• Diagnostic pre-check to ensure regen eligibility
• Forced regen with live soot/temperature monitoring
• Driver advice on passive regen habits and oil types

DPF Replacements & Custom Fitments

If your emissions gear is past saving, we offer new and second-hand replacement options. From bolt-on units to custom-welded solutions, we ensure every install is leak-free, code-free, and fully mapped to your ECU where required.

• OEM or high-quality aftermarket parts
• Custom pipework and sensor integration
• Reprogramming for replaced or upgraded components

DPF Delete - EGR & Catalytic Converter Removal – Off-Road & Motorsport Use

Modern diesel engines rely on advanced emission systems like the DPF, EGR valve, and catalytic converter to meet strict environmental standards. However, for vehicles used in off-road conditions or on closed racing circuits, these components often become a bottleneck. Clogged filters, failing EGR valves, and restricted catalytic converters can reduce engine efficiency, lower power output, and cause constant warning lights or limp mode activation. That’s where our professional DPF removal, EGR removal, and CAT delete services come in.

We offer precise calibration-based solutions that disable and remove unnecessary restrictions from the ECU, restoring full performance while preventing fault codes or regeneration issues. Whether you're experiencing reduced turbo boost, high fuel consumption, or sluggish throttle response, our off-road tuning packages are engineered to bring your engine back to life. Our DPF delete process not only removes the physical filter but ensures proper ECU adaptation, maintaining stable engine operation and proper exhaust flow.

Similarly, our EGR delete service blocks off and disables the exhaust gas recirculation function, which can often lead to soot buildup, intake clogging, and poor combustion over time. By removing these restrictions and reprogramming the ECU accordingly, we help your vehicle regain power, improve fuel economy, and eliminate recurring dashboard faults. For racing builds or vehicles modified beyond street-legal spec, catalytic converter removal is also available with proper tuning to suit high-performance exhaust systems.

All services are intended for motorsport and off-highway applications only. Every DPF delete, EGR remove, and CAT delete we perform is tailored to your specific engine control unit, ensuring maximum performance gains without compromising engine safety or reliability. Trust our experience to deliver a cleaner, faster, and more responsive driving experience where compliance isn’t required but performance matters most.

When and Why You Might Delete DPF, EGR, or CAT Systems

DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and CAT (Catalytic Converter) systems are designed for emissions compliance but they’re not immune to failure. When they clog, malfunction, or cause limp mode, deletion might be the only viable option for track or export vehicles. Key triggers include:

• Frequent limp mode or low power warnings
• Blocked DPF causing excessive fuel consumption
• Cracked or leaking EGR coolers
• DPF pressure sensor or EGR valve fault codes
• Catalyst efficiency errors or excessive backpressure

Make the Right Call – Ask First

We don’t remove parts blindly, and we don’t upsell parts you don’t need. Some DPFs can be cleaned, others must be swapped and some permanently removed. The same goes for EGRs and CATs. Our team assesses your system based on real data not guesswork or quick scans.
