  1. Exhaust problem

    Bugs, faults and irritations (8G)
    Hello guys, I have weird exhaust problem. The car is Civic 8th gen 2.2 ctdi 2009. Sometimes the car goes into a mode where the exhaust sound becomes really deep like a racecar, the engine fan turns on, the mileage goes high and it start to smoke a lot. The car has a DPF, but no "DPF regeneration...
  2. DPF regeneration without DPF?

    General Discussion (8G)
    I bought a great 2.2 diesel civic from an auction and because of that I don't know it's history. Last time I've been in a workshop to do some minor maintenance, the mechanic told me there were welding marks around where the DPF should be and he said I should assume it's been removed. Now about...
  3. MPG Poor MPG + oil still rising despite DPF removal - EGR off

    Engines and Transmission (8G)
    Hi guys, I own a 2007 2.2 i-CTDi Civic with 215.000 km's (=135.000 miles) on the clock. I reach an average fuel consumption of 7.4 l/100km's (= 38 MPG), while driving city+highway. A year ago, I had some troubles with my DPF (engine management light came on a few times, oil level rising etc)...
  4. Shuddering when car stops

    General Discussion (8G)

  5. Exhaust DPF Check system-light

    Engines and Transmission (8G)
    Hi, a week or so ago I got the DPF Check system-light without any "DPF regen required" warnings before. Long story short: Honda couldn't do a forced regen and told me that the mechanic thinks that the catalyst is broken since that apparently controls the temperature the DPF gets. The car has...
  6. Fuel (hopefully) Interesting Article on DPF (Diesel Particulate Filter)

    Engines and Transmission (8G)
    Hi there guys, as you know DPF is a common issue with most diesels, it appears to be more VAG cars but you all have them. I wrote an article on these the other week for our blog/help page BHPplus but thought you may find it useful, rather thank linking it I figured it would be better for you...
  7. Dpf laws!

    Any non Civic chat here please!
    The other half has a zafria and the egr valve has knackered the dpf, so was going to have the dpf removed and a egr delete! But I have since heard that In jan 14 it would have to have it back on if was made with one on for the mot as now is only a smoke test... At the moment I could remove it...
