i think in another name with my skoda it was called a DPF diesel particle filter probably the same thing only diesel im quite impressed with the fuel tank on the Jazz i put 25 quid in and it was nearly full also first automagtic car ive owned
DPF is different to EGR because Diesel engines have an EGR as well as DPF.
DPF (Diesel Particulate Filter) is there to take those nasty cancer causing particles out of Diesel exhaust gas (European legislators have tried for decades to pretend that they weren't there, but Japanese and Americans knew they were, and that is why Diesel cars were never popular in either of those countries).
The particulate filter need cleaning every so often and cars have a tank containing Urea, which is automatically sprayed on the filter and creates a very high temperature to kill those naughty particles and leave the filter all shiny and new to collect some more. The DPF's are prone to fail and allow all the gunge out anyway, and also some people take them off because they clog up and damage the engine - resulting in massive repair bills.
A diesel engine may save you a few mpg, but diesels are so complicated nowadays that they often fail and result in spectacular repair bills that may require you to re-mortgage your house. My bosses 18 month old Mazda has been in repair shop for about 9 weeks waiting parts to rebuild a wrecked engine, luckily it was still under warranty.
here is a quote from a motor magazine----------
Removing your car's diesel particulate filter (DPF) might be tempting, because the damage caused by a clogged DPF can result in four-figure repair bills. An internet search reveals numerous companies advertising DPF removal services, but as well as being bad for the environment this is also illegal, and the Government has moved to tighten up the regulations concerning such practices.
In October 2013 Robert Goodwill, roads minister, announced that garages and testing stations will be required check for a DPF as part of the MoT test from February 2014. The vehicle will automatically fail test if the filter had been fitted as standard but is no longer present.
