    Default An FYI for DPF's

    At the beginning of the year my DPF was 75% saturated. I ran the DPF cleanout procedure on the diagnostic software and it dropped to about 70%. Never having owned a car with one before I thought that was probably normal.
    Roll on a to a a couple of weeks ago and the car is intermittently going into limp mode. After lots of checks I notice the DPF is at 84%. I ran the clearout programme and no change. In fact the DPF would complete the full 8 minute sequence.
    So the cars on stilts and I notice, by accident, that the flexi part of the exhaust has the very slightest leak, you can't notice it unless you really listen.
    So I order a new front section and replace it.
    Car still in limp mode, I start thinking about 300 bills to have it mapped out.
    Took the car on the M56 and ran it in 4th and 5th to Manchester and back. Everytime it went into limp I turned the engine off on and put my foot down.
    Eventually limp stopped. Hooked it up to the Diagnostics - 10%

    So anyone with DPF problems...try checking you haven't got a small leak in your exhaust causing the Regen not to run properly.

    Sorry to butt in on the query; but I was wondering how do you know when/if you DPF needs a regen and how to go about it?
    The only info I have found is to give the car a good boot down the M4?!!

    Cheers

    Drop it to 4th, over 3000rpm and let it go for 20miles. you should feel a small jolt as the extra fuel goes in and alot of smoke.

    You need TECH2, Vauxcom or OPCOM (outside of UK, of course) to check % I do believe good sir. May I also say that reading through one of the other forums I visit, it says prerequisits for running DPF regen are as follows:
    Car must be running at idle
    Car must be warmed up fully
    Procedure must only be carried out ONCE

    Hole in the exhaust was probably caused by the Dpf in 1st place being nearly saturated and causing excess pressure on 1st half of the exhaust.
