Re:


hi Everyone,
its been a number of years since ive been on here, and glad that the xtrail community is still going strong.
my diesel xtrail after 150k kms has decided to throw the engine light on saying the EGR needs to be replaced. My mechanic is talking about blocking it off, and doing a retune for better performance and fuel economy.
ive done some searching on here although can't see anyone that has actually done this, just replaced the EGR. there was reference to patrol's that were doing this although wanted to see if any xtrails have done this?
im keen to do it to get some better performance and freshen up things although want to make sure im doing the right thing

any input will be greatly appreciated
thanks
Sam

Hi Sam,

One of our other members just did this and they are getting P0488 codes occasionally.

Re:


thanks Kev for the link

After speaking to the tuner, reading some posts on here and then doing some looking around about the patrols (based on posts from here) it seemed like a no brainer.

The main concern i had was the DPF light may come on more frequent. My concern on this was the wife does a lot of short trips to school and back. I guess I can always go down the highway and do a burn

When i weighed up the cost of replacing the valve vs the flashing of the ECU, i decided to go ahead with the flashing the EGR on the ECU.

The only thing they couldn't determine was if the valve was opened or closed, so they recommended to block off the valve

Straight out of their workshop I noticed that the car was more responsive. Reminded me of when the car was brand new. Its only been a week, although so far so good.

i will keep you guys up to date with the progress

take care everyone
Sam

Hi Mr Xtrail,
Was toying with the idea of doing same as you with EGR. But as EGR being so tied into ECU and other engine control functions I was warned off it by a guy who used to perform this service...he stopped providing this service as he said the more he looked into the knock on effects of engine mapping he decided to stop. I am so interested in how the mod performs including fuel consumption chages. As far as DPF burn goes it should happen less, exhaust temp will increase which should encourage passive burns. And without engine oil residue getting into exhaust system the ash from the engine oil should decrease. It is this ash that doesn't completely burn away and sets in the DPF like concrete that leads to permanent blocking...where the particular matter from fuel combustion burns away. If you care to pass on how much did this mod cost and what area do you live? I am in Brisbane. I have also heard about a plug in solution to block EGR opening. It plugs into the MAF and tells ECU that engine is to cold to open EGR valve. Please report back how car performs with this mod. Ta
