How it works?!
The DPF looks similar to a traditional exhaust silencer, but is mounted close to the engine. Inside is a complex ceramic structure designed to filter the exhaust gases while minimising flow reduction.
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. When the DPF reaches a certain level of throughput resistance it performs a regeneration cycle to burn off the particulate matter inside the filter.
Common causes for DPF failure
There are a multiple reasons a DPF can fail, the most common are:
Will it prevent me of getting through technical inspection?
No. Job is done by technicians with a lot of knowledge and experience. After our job is done noone will be able to tell if there was something done.
