DPF Filter Delete/RemovalThe exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but as owners are finding out with great expense, the technology is not without its problems.


The DPF looks similar to a traditional exhaust silencer, but is mounted close to the engine. Inside is a complex honeycomb ceramic structure designed to filter the exhaust gases while minimising flow reduction (which would otherwise limit performance). By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited on the walls, so reducing the amount of air pollution. Once the DPF reaches a certain level of ‘Saturation’ it performs a regeneration cycle to burn off the particulate matter inside the filter


What is a DPF?

A Diesel Particulate Filter (or DPF for short) is a filter found in the downpipe section of the exhaust and is specifically designed to reduce the amount of Diesel Particulate Matter (Soot) passing through. The objective of this filter is to create cleaner / more eco friendly exhaust gases being release into the atmosphere.

The purpose of this filter is to reduce pollutants resulting from combustion from being released to the atmosphere...

A diesel particulate filter will gradually become restricted and become more clogged up as a normal part of its service life, a process called regeneration is designed to occasionally 'clear out' the particulate filter. Unfortunately this needs specific driving conditions and when these are not met, the degree to which the filter is blocked can surpass the engine management’s ability to regenerate the filter - leading to problems with power loss (see detailed list below) and even in the absolute worst case, risk to the car due to overheating of the filter.


A blocked DPF can cause many problems including loss of power, economy and throttle response. With more extreme cases, filters that are extremely blocked filters can cause the engine not to start at all.

Symptoms and Fault Codes

There are multiple faults codes and symptoms that can point towards a faulty / blocked DPF.


Loss of power
Lower fuel consumption
Reduced throttle response
Harder / Fails to Start
Limp Mode

009263 - Diesel Particulate Filter (Bank 1): Restricted/Clogged
16855 P0471 001137 - Exhaust Pressure Sensor 1 (G450): Implausible Signal
18434 P2002 008194 - Particle Filter Bank 1: Malfunction


There are two solutions when you experience a blocked DPF.

The first solution would be to take the car to the dealership and replace the DPF with a new one. This can cost around USD2500 and you could potentially have the same problem further down the line.
The second solution is to remove the DPF all together eliminating the problem with no risk of the same problems occurring in the future. (It is the customers responsibility to ensure they comply with rules and laws relating to their home country)

Software Removal

When deleting the DPF in the software we remove all of sensors other than the Pre-Turbo EGT Sensor and Lambda Sensor. Other companies tend to keep all of the sensors in place although some of these sensors are not in use and they can cause issues further down the line. If any of these sensors fail it can cause the car to go into limp mode or constantly turn on the fans.

Regeneration (For Cars Showing Early Signs of Blockage)

For cars that have only just started to show symptoms that the DPF is blocking you may be able to get away with regeneration. If this fails to work the DPF may be too far gone for this process.
