You cannot blank a DPF vehicle, because the functioning of the EGRs is essential to regulate exhaust gas temperatures during the regeneration cycle. Actual blanking isn't an issue, just the consequences. |

I'm not sure of the specifics but I know that's the reason behind the DPF issue. Presumably the DPF needs to be cooled during the cycle also, but maybe software/valves could produce some kind of switching option one day. |

mumble mumble mumble..... I never thinked about the DPF cooling: usually the problem with the DPF is just the opposite....the DPF are always too cold ->ash mass increase -> problem(s)

I don't own a FL2 but have a 2008 Pug 407 hdi 2.0 which has a nearly identical motor. It had an engine surging problem which no one seemed to be able to fix. Eventually a blanking plate fixed the problem. However I was concerned about the effect on the DPF. I decided to use some induction cleaner to clean the EGRs etc. and remove the blanking plate. The surging hasn't returned. |

The opinions regarding blanking a DPF car or not are split, so i will add one more thing to the mix, to blank completely or to put the blank with the hole in it (restrictor)? |

imho the restrictor is a waste: basing on the theory of Mr. Bernoulli, the same exhaust gas quantity will pass....only with a different speed |

Thought I read somewhere the latest MOT tests now doing a gas extra test and blanking may now lead to a fail ? FL2 MY10 TD4 GS traded in at 2 years

Tempting offer but the risk of needing new DPF as a result is too big for me, if it was up to me i would've removed the DPF and EGR completely but it's nearly impossible in Germany ![]() I guess i will wait for other brave men with DPF to try it before me ![]() |

your car will be in limp mode before damaging the DPF so don't worry about it |

Use premium fuels (higher cetane rating for a full clean burn) and keep the EGR clean with a regular cleaner say every 1-2 yrs will make a huge difference !
