This pipe allows you to remove the restrictive DPF filter which is fitted to all modern diesel engines.
The DPF or diesel particulate filter is fitted in the exhaust and catches soot and other diesel particulates, these filters have to go through a regeneration every once in a while which is controlled by the ECU, this usually happens when the vehicle is on the motorway.
If the vehicle has not been able to regenerate the filter for a while or there is a fault with the engine itself the filter will block up and initially cause a fault to appear on the dashboard, if you continue to use the vehicle the filter can block completely causing the engine to stop running.
A new filter from a dealer will often be £500 or more plus labour. Removing the DPF allows the engine to breath more efficiently freeing up power and reducing fuel consumption, it also improves reliability.
This pipe is made from stainless steel and will come with everything you can see in the pictures.
The pipe may require some minor modifications to the vehicle, and will need to have the ECU remapped otherwise the EML light will probably show and cause the car to go into a limp mode. Please ask before purchasing if you’d like to confirm fitment details.
To be sure of fitment check the number of the DPF currently fitted to the vehicle has the following part numbers stamped into the side of the filter:
04L 131 723M
DOC: 5Q0 166 AA
DPF: 5Q0 181 BA
04L 131 601H
