    Default DPF DIY Cleaning

    Hi

    Are there any DIY ways to clan the DPF?

    Iíve had my 09 Vectra for about a year now and run a tuning box on a low smoke setting.

    Iíve had the spanner light come on twice in 30K miles, both times its had to have a DPF ďregenĒ. I donít drive the car like a granny at all, Iím a sales rep so I drive it like Iíve stolen it! (itís a company car!) so it gets daily ďhigh stressĒ revs to blow crap through.

    Normally the limpmode/spanner this isnít a problem until earlier this week when my boss borrowed the car to go to a meeting and the spanner light came on. Luckily he drove it in limp mode back to the office and I had chance to take the box off before the AA man turned up and got me into ďbotherĒ with my boss.

    I clean the EGR every 7k or so, is there anyway to DIY the DPF? Take it off and bake it in my domestic oven maybe? Take if off and give it a rattle over the bin???

    Thanks

    Great site BTW

    there is a 'fix' circulating that if you remove it, block off one end, fill with alloy wheel cleaner (5ltr tin) leave overnight, then blast through with a pressure cleaner, this helps by cleaning out some of the crud. I guess its worth a try before buying a new one. (a Veccy C member has already done this) Incidently, they are now available via ebay for about £300.

    hey Beckman, i was thinking (like you do) after i posted the reply, yours is an 09??? Seems a little young to be having DPF issues, specially since it sounds like you do alot of motorway driving and that should be good for her. My bus spent most of her life crusing the motorways, before i bought her, she has 104k, is almost five years old and the DPF is 78% saturated. So, i was thinking if yours is lower mileage, maybe something else is contributing to the issue. Regens should occur naturally as the car is driven, but, alot of people miss the signs of regen and switch the engine off mid cycle, not good!!!! The biggie to look out for is fuel consumption shooting up to approx 1.8 gallons per hour at idle and slightly lumpy tick over. Its a damn pain and mine usually hits as i arrive at work and i sit there like a muppet for ten mins or so, holding the revs at about 2500 till the fuel consuption returns to o.1 galls per hour at idle.

    This DPF thing interests me greatly as i'm having loads of probs relating to mine.

    Its booked in on tues for inlet manifold replacement with a local vauxhall specialist, whom I trust......everyone recommends them. I have spoke to the lads in there, they have 40 years main dealer exp between them, and they've said that they've never seen or heard of any vec with a DPF doing its automatic re-gen.

    I just find this strange as theres so many threads on here about the re-gen cycle

    I have a tuning box on my veccy estate with a dpf and been on over 6000 miles now with no probs but since having the box on I notice if I potter around town then give her full beans to the redline she leaves a plume of black soot looming about I can see it in my mirror sitting there while I fly off lol but j just give her a good rag every day clears out all the soot for sure

    When i get fault coded for my dpf or when it gets blocked up I will be removing it from the car and replacing it with a straight through pipe at least I get more mpg and more performance then
