2014 GU Fault Diagnosis

[Wildthing_507]

Thanks Threedogs, had a sneaking suspicion about that. I've heard of others doing it on different makes but didn't realize the Nissan might need it.

Also, I wasn't sure what size hole. Now I know.

Pretty sure most drill a 6mm to 10mm hole ,to send a maessage to the ecu the egr is still working
Have a search Im sure theres plenty written on it. Start with a 6mm hole and see how you go
Could I also suggest you buy a Scan gauge for your patrol.
Great piece of kit, a sort of must have, clear faults out the
middle of no-where if required

Scandisk, one of the many things on the list. Probably the next thing.

Hey wild thing, I am going to chuck the EGR blanking plate in my 2014 on Saturday, how many Kays have you got on yours I just ticked over 30,000, and decided to block it (i was a bit worried about warranty) i got a free EDS with a subscription to 4wd Action so I thought stuff it if I have drama's I can just remove it ($7 on ebay) are you running catch can needle valve and all that nonsense or just the blanking plate?

Hi Fatty Man, 35,000. You won't believe the difference the egr plate makes. I had a chip which made a big difference but I took it out when the dash light came on. Other than that, nothing else yet. Catch can next though. Dawes valve I guess eventually but not a priority yet.
I'm sure the light is because of the plate (EGR not registering on the sensor) but for you, the EDS should clear it. If the little bluetooth dongle and Torque pro app won't clear mine I'll take the plate out to get it cleared and put a small hole in it and put it back in afterwards. It makes too big a difference to leave it out.
As for warranty, the question is whether the crap building up in the intake manifold is something to be ignored? As for me, it would drive me insane knowing that there is the extra power and cleaner running available and not take advantage of it so I'll risk it. There are mixed reports from people who have had warranty done on other things and left the plate in with Nissan knowing it's there. Someone has said that Nissan can check to see what errors have come up and been cleared which put me off clearing it myself but as someone else said the chances of them looking are minimal to say the least. They'd have to be a pack of you-know-whats to not give you warranty on something unrelated to the egr fault code.

Also, let's face it,
1. you can always take it out. It's a bit of a bitch the first time you put it in but like everything, it would only take half the time from then on.
2. These engines are becoming very reliable and the chances of anything major needing warranty are pretty slim.

I'll run the gauntlet on warranty for the extra benefits.

well ive got a EGR solid plate - not hole it in - when i scan with my wifi and iphone using tourqe its got a fault code of low EGR flow, but no dash light - never had one yet. Im in a CRD but out of warranty so dont care now. I personally dont see the point of blocking the EGR if your going to put a hole in it. A hole lets the crap through.

That's true but if a small hole keeps the light off it's still gotta be better than the Ø30 odd hole that's there without it. Just letting enough through to keep the sensor happy instead of flooding the whole intake with the crap. I'd rather not have the hole so if torque pro clears the code and it's not coming up too often then I'll leave it out.
If I do put a hole, I've read a post where the guy got away with just a Ø3 hole so that's where i'd start.

The sensor doesn't always trigger the engine light. In owning my 3L patrol, a 3 year span, I have had the light come on twice... Easily reset-able.
And somebody here had a photo up once of a blank with a hole, and the hole had all the soot crusted up around it, pretty much blocking it anyway.
When the engine light comes on, it is only a warning letting you know something is up. It does not alter the performance in any way, like putting it into limp mode for example. So if you have a scangauge or Torque up (as mentioned above), i would not be putting a hole in it. It defeats the purpose I think.

Thanks Hodge.

Twice in three years I could certainly live with especially if I can reset it myself.
