risk of particle filter in 3008

[Jason Cordina]

hey to all,

my multifunction display just displayed this error including engine warning light and audible sound for about 30 sec and then went off by it self

the car was brand new and it have only 3000km

can anyone help please

thank you

it would be hazarding a guess mate, cant think of the Filter being blocked on the car. Its deffo something else.. As you car is still under warranty I would reckon you go to the dealers..

that is my nightmare my friend in fact that will be my first thing i do next monday i tried to find that error inside manual but did not find nothing except that it could have been that the car was regenarate the filter which for me its like reading japanize.

anyway 3 things i could say from my side is that i normally drive it not more then 70km and last drive i did i almost drove it on empty tank and i left it for 2 weeks in garage

well now lets see what delaer tell me on monday

two things i dont like now in this car dual mass flywheel and this i guess who ever gave it best car 2010 did not own one

thanks my friend for answering

ps i also noticed that this is happening only when i try to accelarate to hi speed mean more then 90km after i pulled around 2 times 130km and it looks that ok now maybe because i normally drive it very slow this happen because lets face it this car is brand new it did not even reached 3000km yet

Well i took the car to Peugeot Garage, they connected to the Planet and did some tests, the computer showed that the car tried many times to do recycling of the filter but no succsess in fact it gave this error

PERMANET FAULT IN FILTER READING MAXIMUM NUMBER OF TIME REACHED TO REGANARTE

so he explained to me that since we dont have long roads in Malta i need to push it a bit on 1 and 2 gear sometimes, and when warning shows up on screen i need to drive it around over 3000rpm for few time until she cleares up, in case this does not work and it will continue to show up the warning they will replace the sensor under warranty

he also told me not to worry since this is a normal proceger for the car in fact the car do this thing every 300 or 600 km on its own and if you stop engine and this does not get clear she tries next time until she pops out this warning or get the filter complety blocked

unfortuntly i did not buy a car to go racing around with 1 kid and a baby and a wife so i drive the car around 60Km/H to 70Km/H for twice a week so i will try my best to use the turbo from now on--LOL-- BETTER TO JOKE A BIT!!!!

NOW WILL SEE!!!!

Diesel Particulate Filters (DPF)
Reducing diesel soot emissions by 80%
Changes to new car emissions legislation scheduled for 2009, the so-called 'Euro 5' standards, will make particulate filters as commonplace in diesel car exhausts as catalytic converters are on petrol cars.

The goal is an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems – AA patrols are already being called to cars with the particulate filter warning light illuminated (indicates a partial blockage).

It's clear that changes to driving style may be required too for maximum benefit from these systems.

How do they work?Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' – the accumulated soot is burnt off at high temperature to leave only a tiny ash residue. Regeneration may be either passive or active.

Passive regenerationPassive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Many cars don't get this sort of use though so manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey's a bit stop/start the regeneration may not complete and the warning light will illuminate to show that the DPF is partially blocked.

It should be possible to start a complete regeneration and clear the warning light simply by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights illuminate too. At this point driving at speed alone will not be sufficient and the car will have to go to a dealer for regeneration.

Expensive repairsIf warnings are still ignored and soot loading continues to increase then the most likely outcome will be a new DPF costing around £1000.

Mainly town based drivingIf your own car use is mainly town-based, stop/start driving it would be wise to choose petrol rather than risk the hassle of incomplete DPF regeneration.

DPF additivesThe most common type of DPF features an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be relatively hot so that passive regeneration is possible.

There's not always space close to the engine though so some manufacturers use a different type of DPF which relies on a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Tiny quantities are required though so a litre of additive should treat around 2800 litres of fuel, enough to cover 25,000 miles at 40mpg.

With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.

AA experienceWe're seeing some evidence of these systems failing to regenerate too, even on cars used mainly on motorways. It seems that on cars with a very high sixth gear engine revs are too low to generate sufficient exhaust temperature. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.

Check the handbookIf you buy a car with a DPF fitted it's important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.
