Hi as some may know a few days ago I fitted a EGR delete kit and all has been well until this morning.After a brief drive I noticed the car sounded louder from under the bonnet stopped had a look and it turned out the small metal pipe that goes onto the inlet manifold that was attached to the old EGR had split causing the blowing sound.Anyway sorted that removed that pipe and fitted the delete plate back onto the inlet and stopped it blowing.Now what I've noticed is the car seems to not boost straight away and seems sluggish until you get the revs up higher it will start to pull ok but not as strong as it usually does.The car actually sounds louder now as well compared to yesterday sounds made in know but it does plus my MPG are not as good either.Had a chat with a friend and he said that the car will need remapping to map the EGR out which I'm getting sorted shortly.Just curious if anyone else has had a similar issue it's almost like the car is in a kinda limp mode bare in mind everything was fine before so I can't see it being nothing major and the car still drives fine just slower at the min thanks.

Just had it tested for faults and no faults found or error codes etc.
-
What year is the car and engine?
I did the same thing as you and left the flexi pipe on :lipsrsealed:
Fitting the blanking plate to the manifold cured the problem mind :undecided:
Have you blocked the pipes that were going to the EGR valve (you are meant to by the way)
-
Yeah blocked the vacuums off however they wasn't but its still the same.The cars a 2002 100 bhp pd it had been remapped before I had it not sure who buy though.Car just seems to hold back until it hit about 3k on the revs and its bit louder.Mate reakons the fresh air or delete kit has knocked the old map out.
-
Shouldn't make that much of a difference if any at all :undecided:
-
Don't know then lol have to see what the lad says who does the mapping etc
-
It must be to do with the delete kit as it was perfect before so I can only think it needs mapping out have to see.

I cannot see how that would affect your car in any other way than posotive?!

I would start with a smoke injection test into your turbo pipes to see if you've got a leak somewhere, thats the easiestbway of finding a boost leak. It could be a complete coincidence. But I'm finding it strange that there's no fault codes..boost leaks would usually cause a fault code...air mass meter might not...

Boost leaks never brought a code up on my 130. I had the EGR to intercooler pipe blow off, the red turbo pipe split and the intercooler was leaking and at no point did it flag up a code :sad:

Really?! That is a suprise..9 out of 10 at work will flag up a loss of boost code, especially volvo's!! Haha
Even more of a reason to get a smoke test done then :)

Yep. I think the only time i had a code was when the flexi pipe snapped off and threw me into limp mode
I dont think there were even any codes from when my turbo went pop!! There were deffo no warning lights lol
-
I usually find intermittent loss of boost or irregualar boost, would really expect something from a pooped out turbo :shocked: haha

Thats usually if you hit limp mode. Never hit limp mode with the boost leaks i had Just hit 'f**ked mode' when the turbo went :laugh:
-
I don't even think I got anything when I went into limp mode!
I'v driven like 30miles with the pipe to me EGR almost entirely out without knowing about it or a light.
Just check all of your boost pipes for leaks, take the bumper off to make it easier.

Well at the moment I havent a clue why its behaving the way it is :huh: a friend of mine at R Tech explained that the EGR should not really cause any powerloss etc as already mentioned on here.Im taking the car into a garage I use tomorrow afternoon he is going to have a look at the car for me as I just havent a clue with anything to do with turbos and boost etc.The car is still driving fine as im still using it for work etc always the way with me I have unusal faults :grin: thanks again for all replys etc and if anyone else has any feedback what it could be post away as ill be passing it all on to the chap tomorrow thanks.
-
Does the EGR delete have a take off for a boost gauge? Has that been blocked off? I assume all the o-rings are in place?? :undecided:
Just want to make sure you've covered the basics as its often those that are overlooked :smiley:

Took the car to my friends today as I was showing him what ive done I spotted a vacuum pipe hanging down which was the vacuum that connects to the bottom of the N75.Reconnected it and the car is now back to normal :rolleyes: happy days :grin: thanks again for your help
-
School boy! You won't let that happen to you again!!
Glad it is all fixed mate! :afro:
-
Ive lernt so much in a few days :grin: thanks again :wink:
