    Default Particle Regen (3.0 V6 CDTi)

    Getting super annoyed at this. I read a directive from GM that the particle filter regens itself (to burn off the soot from time to time), when certain criteria are met, including speed, time since last regen etc.

    Anyway, when mine does it, my mpg goes from 0.2 per hour (when running idle) to 1.0 gallons per/h. This will last for 20 mins upwards (20 mins is the minimum for a regen i believe).

    However, the car stinks of burning diesel. Its 10x worse than being behind a bus, so much so that it makes me feel ill and gives me a headache. Its worse when stood, when moving it isnt as noticeable but its ****** horrible. The alternative is to kill the engine and interrupt the regen, but i dont like doing this.

    Regens are occuring every 3-4 weeks or so.

    Does anyone else experiance this type of problem? Car is a 2008 model btw.

    Cheers

    Bad piece of technology tbh and is putting deisels behind petrol again. And with the advent of these EU directives and regulations they will be a compulsory part of every new deisel produced.

    They say to cut down the amount of time s the regen occurs you should drive the car hard a bit more.

    I second Gazza4 on that one, giving the diesels a bit of stick for a period when warm does it the world of good. Just remember to leave it idling for a while once you have "stretched its legs" so to speak!

    I believe that the newer (EURO V) cars eat a larger percentage of their recirculated exhaust gas, and use even thinner oils in their engines and gearboxes.

    One of the drawbacks of an engine eating more of a percentage of its recirculated exhaust gas is that it tends to produce larger soot particles. For this we have our friend the DPF, and if you want to reduce emissions even further, you have to eat more exhaust gas and therefore you'll need a bigger DPF which will need to be regenerated more often, and use more fuel in the process.

    NOx g/km actual and proposed limits.

    Euro 3: 0.50
    Euro 4: 0.25
    Euro 5: 0.18
    Euro 6: 0.08

    NOx is the 'smog' inducing greenhouse gas produced when combustion temps are high. The introduction of exhaust gas into the combustion process reduces combustion temps.

    Yes, the Euro 4 V6 CDTI eats twice as much crap as the Euro 3 CDTI!

    Im sure someone on here managed to by pass their DPF albeit on a 1.9 150.

    Think they cut out the DPF inside and welded it back up then they had to crimp a vacuum tube somewhere in the engine near the firewall/bulkhead or something to that effect.

    thats what happened but they just cut some pipe and folded it in on itself and they cleared the fault and never had it back again.
