1.7 Dti/Di Egr Delete ASTRA/CORSA/COMBO

[@rafalipinski4048]

This operation costs me about 10 GBP in Poland, I am on it any time soon, very helpfull instructions.

[@BOB-gu5qf]

I’m glad to help thanks

Good job, but there's the ecu on the engine to relocate. Me, as I changed 3 of them, i just made an L shaped flange with two bolts on the side of the right shock absorber place (you will find two bolts flanged on the metal), then i drilled two holes in the flange and put the ecu. I also opened a 30-40cm of the original electric cords and cut two as they are not longer than 8cm and then goes directly from a sensor on the fuel pump to the edu plug. Then added a piece of electric cord to make these two cords longer

Hi Bob, just wondering: i havent delete my egr yet...but, can we just screw a bolt in that T shape in that 1 left hose conected to nothing? Like that little 2/3 cm hose? I dont want to take the T conector off. What change if i close that hose anyway even if i didnt delete the egr?? Thanks.

Hi mate. Great video thanks. Just wondering what I do with the other end of the 40mm astra boost pip once it’s on the intake manifold? Cheers

[@perfektrepairs7934]

I never blanked of my egr control valve oops lol I’ll do that tomorrow good video mate

[@BOB-gu5qf]

Cheers pal & it's fine you sometimes get a weird clicking noise from the egr solenoid if it's still getting vacuum. The noise goes away when the vacuum is blanked off👍

Hi have a opel corsa c 1.7 dti 2001 I don’t get turbo acceleration and the car on 5th gear can hardly reach 90 klm ph if i plug the air intake sensor won’t ever reach 50 I unplugged drives ok turbo control is perfect had the egr clean it up

Hi mate, awesome detailed video. I have a dti turbo to intercooler hose and only one end is 40mm. The other end is aboht 35mm and wont go over the cut black metal pipe. Do you have to just stretch it on?

[@BOB-gu5qf]

Hi sorry for delay just noticed comment! throw the rubber pipe in some boiling water for a few minutes, this should do the trick👍

Can u remove the egr while it isn’t remapped and wil it not go into limp mode ay botherd if engine light on cause of it

[@jakubjedrzejczyk473]

Hey dude can you help me? I've got a error p0400 from egr and I don't know what to do I've blank hoses but should I blank a hose from the solenoid? Sorry for my English

[@BOB-gu5qf]

Sorry for delay! Remove the 2 solenoid hoses, take the vacuum feed hose( hose that comes from the t-piece)install screw in there to prevent a vacuum leak. Also Leave solenoid electronic connected👍

[@jakubjedrzejczyk473]

@@BOB-gu5qf hi I still have this problem since then , from time to time , driving with the same speed and bam p0400 , I've change everything from vacum pomp to new houses and new solenoid and still this problem, when I turn off the engine error disappear and I have full power again , I've done everything like y said

[@Adrian-re9fh]

@@jakubjedrzejczyk473 I've got the same problem, the issue here is that the MAF sensor which is the one measuring the air entering the engine detects that the egr is not opening by looking at how much oxygen is entering in the engine. A remap should be done to get rid off that error. I tried with kess V2 and Ads Professional EGR remover but the error still appears. So I guess you need to map out the EGR code in the ECU.

[@perfektrepairs7934]

I got a issue with my dti :( random rough idle not all the time but now it’s getting worse when I go to pull away sometimes it holds back loads and smokes like a train then if I let of and on again it’s fine I noticed I had 2 pipes coming of my old egr motor I blanked both one was connecting to the 3 piece T and other was of the egr I removed an I supposed to blank both ?

[@BOB-gu5qf]

Sounds like the crank sensor, have you done the pedal test for fault code? 0335 is crank sensor. Btw You don't need any hoses going to the egr solenoid, just blank the t-peice hose. Or better yet remove the t-piece altogether & join the only two hoses left( which is for the boost control solenoid )

[@perfektrepairs7934]

BOB131 there’s a 3 way connector back left of engine do I not need any of those pipes ? And cheers mate I’ll do peddle test tomorrow nice one

[@BOB-gu5qf]

Aye that's it, just remove the egr hose from that t-piece & blank the NOW spare outlet on the t-piece. Or better yet , remove the t-piece altogether & fit a vacuum hose jointer, this is to connect the two hoses that's leftover👍btw if you pause this video & look closely I'v fitted a better t-piece but with a screw in the 3rd outlet hose.

BOB131 I get you nice one mate appreciate the help

[@almac6316]

hi mate sorry to mither but i did the egr delete today and also changed the coolant but my van doesnt seem to get up to temp, i know it takes longer to warm up with the egr deleted but not sure if its that or coolant related. any chance u could shine a bit of light for me? cheers

[@BOB-gu5qf]

No problem the egr shouldn't make much difference to temp. Have you bled the coolant system? & Does the interior fans blow hot air?

[@almac6316]

@@BOB-gu5qf yeah bled it to my knowledge of squeezing pipes and filling reservoir but doesnt seem to get to temp. and yes interior fans blow hot air. at least i know ive not done something wrong with egr👍

Looking good mate. Where you from. Could get a dti meet.

Cheers pal & sounds good im near Aberdeen Scotland wbu's? my bro rocks a dti astravan also👍

[@dmcn3226]

@@BOB-gu5qf just put a multimeter across the pot with the engine running and the resistance disappears. Think it's something to do with the map.

[@BOB-gu5qf]

It Could be the map but evry does work on the di. It's not as extreme as the 1.9tdi's but defo works, I'm gonna put a multimeter on mine just to see where the sweet spot is.....

[@dmcn3226]

@@BOB-gu5qf let me no how you get on mate. Like I say I get a reading with the engine off but as soon as it's running it doesn't give me a reading. Strange like gonna get another look at it tonight.

[@BOB-gu5qf]

Aye will do pal & that's super weird like!!🤔......, Btw got 6 vans keen for the meet so far. But Gonna do a shoutout video this week for more. I want to get my astravan done 1st it's out o action atmo😩

Hi there,do you have to unplug the egr solonoid also after this mod?

What about the ecu, you don't have to reprogram???

Hi my8 opel corsa c 1.7 dti 2001 turbo is in perfect condition but I don’t get no turbo boost any idea 💡 can a mass airflow sensor make that not to work ?

Ever thought about selling ready made ones 👍👍

[@oliam123]

Can anyone tell me where the oil pressure sensor is on th 1.7 di?

[@BOB-gu5qf]

Its on the right hand side of the engine(gearbox side) almost directly below the thermostat housing. Its a single cable that goes to it & cable has a rubber boot/shroud round it. Cable simply pulls straight off, no crappy plastic clips etc

[@oliam123]

@@BOB-gu5qf thanks 👍

[@oliam123]

@@BOB-gu5qf also I've not attempted it yet but the rocker cover to take it off, how is it done with them 4 pipes in the way?

[@BOB-gu5qf]

Its easy enough! just slacken the 4x17mm fuel lines & separate the metal lines from the injectors. Then remove the 4 rubber seals that surround injectors( 8x10mm’s) be careful to not damage these seals though. The rocker cover can now be removed(all 10mm heads bolts iirc🤷‍♂️) it is a wee bit fiddly to get over injectors. Once it’s back together leave the 17mm metal lines hand tight as there’s air in the fuel lines. Turn the engine over & watch them until there’s fuel leaking out all 4 lines,try be quick on tightening them, also grease the rubber seals before refitting them! Keep me posted🤙

[@oliam123]

@@BOB-gu5qf thanks for that, can't find how to do it anywhere. I've done a few things to it like the water ingress, clean the egr and anti roll joints to get it through mot. Going to do the rocker cover soon👍
