ok the particulate filter what an interesting story i have to tell
I bought my 2.2hdi 406 lovely car (for me) get 50 mpg decent performance and more creature comforts than i have had in any previous car.
The problem the particulate filter to which i almost now consider myself an expert.
what is it
on the 406 its is a CAt with smaller holes attached to the front of the cat. can it be removed easiy, yes, can it be cleaned yes.
now when i say cleaned from peugoet they send it away to france to be presher washed clean then sent back, you dont get new ones from the dealer you get cleaned ones.
They cost £350 plus £500 surcharge plus labour at £80 an hour and then the eolys topping up at £30 a litre to which you may need up to 5 litres.
can you source either the filter or the eloys form anywhere other than a dealer, not likely.
How long do they last ? well my model 406 reckons 50k miles.
Can it be bypassed, no. It is imbedded in the ECU, can you do what some do with a cat and stick a chisel through it ?
No because there are pressure sensors at each side measuring for differential pressure and by putting a hole in it you set them off.
What happens under these circumstances ?
It goes into limp home mode meaning travelling at 2000 rpms and under till taken to a dealer.
do most modern diesels have one ? answer yes. look for a startup light on yer dash which will equate in the manual to an anti pollution light. this means it has a particle filter and will cost you god knows what to replace at some point.
Did mine go 2k miles after buying the car ? yes, how much heartache dfid it cause, lots how much to repair ? I sourced a brand new one from ebay for £180 and a local Peugeot specialist fitted it for £40.
As for Regen well there are two types the self induced which is supposed to be like mentioned before, then there is the manual regn which involves the dealer, a lap top and them revving yer car at 5k rpm for about 20 minutes leading to heat out the back of the exhaust that has been known to strip paint of cars ( no lie)
I hate the particualte filter, theres no need for it and no reason for it to be there.
EDIT: form what ive read on the subject they started to be implemented after 2001, i,e my 406 has it but the hdis of the same age didnt so it wasnt on every car when first introduced
