    Prefacelift (2003-07) iCDTi - replacement of injectors and ECU

    Fahad, the EGR is not clogged up according to my mechanic. I specifically told them about it, with my previous history of an EGR being diagnosed and not being the problem. I cleared the codes before taking it to Honda and then they did not see any EGR code.

    DIY 7th Gen Pre-Facelift Diesel Fuel Filter Change

    I was able to do replace the fuel filter with few problems, and re-tighten that bolt - I had to do the bolt with a ratchet while holding a nut on the other side with a round spanner. Took a few minutes but was done. Easy to prime and bleed and had no problems, so job done. It made no different...

    Prefacelift (2003-07) iCDTi - replacement of injectors and ECU

    Thanks Fahad - hope you are doing well and I don't forget your help a couple if years ago Honda were the 2nd opinion this time :unsure: my mechanic had a look at the EGR first (was coming as a code) and it's definitely not clogged... EGR was one of the codes (5002) they found, but there were...

    Prefacelift (2003-07) iCDTi - replacement of injectors and ECU

    DIY 7th Gen Pre-Facelift Diesel Fuel Filter Change

    Hi Great write up and the pictures are of excellent quality I'm about to do it for the first time. I started having serious problems with stalling, going into limp mode and EML coming on (with lots of error codes etc) recently after a garage having fitted a non genuine filter (I can see by the...

    P2004 - IMRC Intake Manifold Runner Control problems

    Hi Steve I had the hesitation you describe and yes, the Frequency solenoid was the cause, and is said to be the usual culprit. If you want to be sure, like me, have the valve manually checked by Honda to confirm it is faulty. Mine was checked at at Honda Holdcroft and I replaced it myself...

    P2004 - IMRC Intake Manifold Runner Control problems

    (Quick update and thanks to Fahad for his time and help). The car is a little better after being put back to stock. The remap has been removed and the car is back on the factory map. Just before this the engine was low on power (think 120bhp) which was more obvious just above 2400rpm...

    P2004 - IMRC Intake Manifold Runner Control problems

    Fahad, the problems were there before the map. Maybe the technician who did the remap can be considered a little irresponsible to do so in an unhealthy car....I did ask the question... However, as he explained to me, the map made more visible other areas of concern which needed doing and we...

    P2004 - IMRC Intake Manifold Runner Control problems

    Fahad, No, I haven't been there again because it is far for me to drive and need a day off work (another good thing about HH is a courtesy car for me to get to work). I did find very interesting a mention you made about mapping out the EGR, but I agree I should be taking care of the...

    P2004 - IMRC Intake Manifold Runner Control problems

    Well, hello again. I must post again because my situation is yet to be resolved, After leaving HH I was quite happy with my car was showing the full power of the remap, albeit smoking a lot. I expect it was because they cleaned the pipes. It gradually reduced and now it barely does. After two...
