    D3 V8 EGR

    Hi all,
    After a bit of searching and not coming up with much, want to ask about blanking the EGR on an early D3 V8. Mainly because I've just had it done by my local Landy specialist. It was in for a few items, and they detected a leak in the EGR (sticky valve, I guess), and blanked it off, and it seems to be running fine. I know this is commonly done in diesels, and done it myself in a few older models, but they indicated it may throw up a computer fault from time to time, and if it gets annoying, they're happy to replace the non-functioning EGR with a new one.

    If the V8 can happily handle not having an EGR, I'm happy not to replace it.

    Has anyone with the petrol V8 blanked off or removed the EGR, or should I be looking to replace it with a functioning EGR at some stage?

    Not having it in use is great for your engine internals - it keeps the intake much cleaner, however EGR is used to reduce harmful NOx in the exhaust fumes. So, if you are ok with the air we all breath killing us just a little bit more, then go for it.

    No error code so far? How long have you had the blanking plate in for? Can the EGR system be turned off electronically (e.g. through Nanocom or the like)?

    With a software patch it can, that's what they do with the TDV6 with EURO4 + models.

    So is there actually a software patch available for the V8 then?

    We all fit snorkles to try and make sure we are getting nice clean air into our engines and yet people don't worry about getting the filthy exhaust gasses pushed back through the engine via the EGR systems, The first thing I did to my Navara was to blank off that sucker
    NASTY little things EGR valves

    D3 V8 EGR

    True, but emitting lots of exhaust fumes that aren’t healthy is slightly different than emitting lethal fumes. There is a reason for EURO 6 and the statistics of deaths from exhaust fumes in cities bear it out. I guess my point is that we all play a tiny part in the world order. Even diesels, of which I own one, have awful exhaust fumes, forgetting the actual makeup of it. The fine particles are not good for human lungs. This is unfortunately why the government has to legislate such things out as if we were individually left to make our own decisions, we’d choose what benefits us 99.99% of the time, not the greater good overall.

    Anyhow, sorry, I’m no angel, it was just food for thought, and off topic.
