DPF Removal & ECU Remapping
DPF Removal & ECU Remapping
At Onyx Performance, we specialise in Diesel Particulate Filter (DPF) removal and ECU remapping, offering a permanent solution to DPF faults, blocked filters, and engine warning lights. Our expert team ensures that once the DPF is removed, your vehicle runs efficiently and without future regeneration issues.
Modern diesel vehicles are fitted with DPF systems to reduce emissions, but over time, these filters can become blocked, leading to reduced performance, high fuel consumption, and expensive repair costs. Our DPF delete service is designed to resolve these issues and improve your vehicle’s reliability.
Why Remove the DPF?
Diesel Particulate Filters trap soot from exhaust gases but can cause serious problems when they get blocked. Common issues include:
– Loss of power and poor throttle response
– Frequent DPF regenerations wasting fuel
– Dashboard warning lights and limp mode activation
– Expensive repairs or DPF replacements
By removing the internal filter and recalibrating the ECU, we eliminate these problems while improving fuel efficiency, throttle response, and reliability.
The DPF Removal Process & ECU Recalibration
Step 1: Physical DPF Removal
We modify the original DPF chamber rather than fitting a bypass pipe. This involves carefully opening the DPF unit, removing the internal filter, and then sealing it back to maintain the stock appearance. This ensures improved exhaust flow and performance without affecting the overall system structure.
Step 2: ECU Reprogramming
Once the DPF is physically removed, we remap the vehicle’s ECU to:
– Disable DPF-related sensors to prevent error codes
– Stop forced regenerations that affect fuel economy
– Optimise fuel delivery for a smoother drive
– Resolve common DPF-related warning lights
Our DPF delete remap ensures the vehicle runs efficiently without any future DPF regenerations or fault codes.
Fixing Common DPF Fault Codes
A blocked DPF can trigger various error codes and force the car into limp mode, restricting power. Our ECU remap resolves the following DPF-related issues:
– P2002 – DPF Efficiency Below Threshold
– P2453 / P2452 / P2454 – DPF Differential Pressure Sensor Fault
– P2463 – DPF Soot Accumulation Restriction
– P0472 – DPF Pressure Sensor Signal Too Low
– P2458 – DPF Regeneration Duration Too Long
Once the ECU is reprogrammed, these codes will no longer trigger, allowing for smooth and trouble-free driving.
Benefits of DPF Removal & ECU Remap
Many vehicle owners choose DPF delete solutions for better performance and lower maintenance costs. The benefits include:
– Improved fuel economy with fewer regenerations
– Better throttle response and acceleration
– No more DPF-related warning lights or limp mode
– Reduced long-term repair and maintenance costs
– Enhanced exhaust flow and turbo efficiency
For those looking to further enhance performance, we can combine DPF removal with ECU tuning, adjusting settings for increased power and efficiency.
