Does CRD GU8 require EGR block etc.

[Blacklotusdog]

Catch can is up to you, some people fit some don't. If you get rid of the soot via the egr block then it can't mix with the oil in intake which the catch can would remove so can't form a sooty deposit. I think you will find most people with crd just do egr block.

Scanguage 2 is great bit of gear, you can use it to check your boost isn't spiking once egr blocked, shouldn't be issue as crd motors seem to be pretty good at controlling boost. Can also help you learn to drive more economically, and can monitor few other things like coolant temp.

I think you will find the crd is pretty reliable compared to the early DI. There is some around now with some pretty high km on em.

Scan gauge will give you boost, egt shouldn't be an issue and is pretty involved in fitting. I would grab a scan gauge and get an idea of what your boost does in diff driving conditions then whack in egr block and check again. Make sure your boost does not spike over about 16psi, you should also see you car now running a higher boost when cruising on hwy speed. Mine sits around 6 I think.

Thanks man! If I can get away without the catch can thats one less job to do, cant find a good reason not to do the EGR block thats definitley on the cards with the scangauge.

Does Ferret still do the block plates?

I am in two minds regarding egr block. Putting it on pretty much voids the warranty, mine is a new 2012 GU8.
From what I have heard (it could be a rumor) , even if you remove the egr block and clear any error codes before the service, the dealer is able to see the that the ECU has been cleared or any past error codes unless a full factory reset of the ECU is done.

If I block the EGR than the dealer can blame a lot of future issues etc on engine tampering.. if I dont block then the engine gets full of crud.... not an easy decision....

How long is your warranty for Ronin? I juts bought a 08 so no warranty issues there. Dont plan on Nissan ever touching it again to service either. Got a good mate who runs his own diesel mech business and is a keen 4wd buff to.

Just wait till its out mate and then fit it?

I got the 5 year warranty. waiting 5 years means there will be 5 years worth of crud build up.

I also noticed that Nissan has put red tamper evident paint on the bolts of the egr.Pr1cks

Bummer, Nissan must have cotten onto it then!

Looking at it in a positive light, at least up to that 5 year mark if your truck stops due to much crud build up, you can get it fixed under warranty!!

Hey ronin I have 2012 GU8 too. I have had one service with Nissan which I took the plate out for just in case it through the engine light. I don't think the codes are stored, once it's cleared it's gone. If you service your car at a Nissan dealer you will be lucky if they actually change your oil let alone go searching for cleared codes in your ecu.

Also as far as I know they have to prove the modification caused the issues if they don't want to honour warranty.

One final thing your warranty is still valid as long as your car is serviced by a qualified mechanic. So of you don't want to pay ridiculous prices and want your car serviced properly take it to a good mechanic you trust and only takeout to Nissan for warranty issues. Once you have put in the egr block it will only take you twenty minutes to pull out, So it's easy to remove

Haven't seen him around on forum lately but apparently is still around. He sells his gear on eBay do may be easier to grab from there.
