There is also an additive you can add directly to the fuel tank to help with the regeneration process . Think all diesel cars after 2007 have them fitted by law but you can remove them if you like
    Not on some of the newer ones from what I have heard. Also the VW apparantly no longer have them fitted.

    I did a DIY job on mine cleansed it with caustic soda and its been fine since.

    Get the car remapped to remove it and manually break it out of the car. It serves no real purpose tbh other than to save the cat. But the cat has years and years of life in it. Or you could get someone to regenerate the PF filter, it burns the gunk out of it and leavs it like new. The person that recaps it can also do it. It only costs a fraction of buying a new one for it to fair 2-3 years down the line again.

    I know this is an old thread but just for information.
    I have an 09 citreon berlingo and page 127 of the manual it says it is caused by
    saturation of the filter after prolonged urban type driving, low speed, long traffic jams.
    It says
    drive at a speed higher than 40mph (60km/) for at least 5 minutes as soon as possible when traffic conditions permit.
    If after this the light is still on then contact a citreon dealer

    the easiest way to clean the filter is to drive on a long stretch of road with revs over 20k for around 20 minutes. dont have to go fast just knock it into a lover than normal gear as long as the revs go over 20k for the duration needed.

    you mean 2k buddy.. not 20k..

    Diesel vehicles hit the limiter at around 4k - 4500 rpm.. F1 cars hit the limiter at 18k rpm..

    Must be a sporty type of diesel you have

    Actually it's not enough to do a decent cleaning; better would be to give the motor a decent load for some time; a high-speed motorway trip would be fine (say some 20 minutes at a speed of 75MPH), or better: pull a caravan in a mountain trip!

    I have had to do this 4 times with my (now) 3 year old VW Golf but it is mainly used in town, with a few burns up the local autobahns.
    However 3 weeks ago, my wife forgot to mention the light had come on and it ended up in the garage, where they successfully regenerated it.
    Absolute pain, but no need to replace

    Hi guys - Im new to the forum so hello!

    Had my DPF light come on recently too but I code VWs/Audis as a hobby so luckily for me, I managed to activate 'regeneration' mode which circulates exhaust gasses to the DPF taking it from 200C to about 800C. This mixed with 2000+ rpm for 15 minutes took me from 80% blocked to 0%

    You don't generally need to activate regen mode to clean it but you clear it up MUCH quicker if you do! (15 mins compared to 1-2 hours for an 80% blockage)

    Happy to give anyone close (york) a hand with regen if you ever need it!

    Ian

    Also be aware now mot testers have to physically check the a dpf is still fitted and if not and should be its a fail and has to be refitted so be careful dpf removal could be very costly in the end its also technically illegal
