Hello fellow D.I.Y mechanics:d
The aim of this thread is to hopefully give you enough information to remove, clean and re-install the EGR Valve on a 1.9dCi Engine.
My Car:- Renault Laguna 1.9dCi Dynamique 120Bhp
Difficulty:- **
Time:- 1-3 Hrs
Items Required:-
- Ratchet Set
- Medium flatblade screwdriver
- Large flatblade screwdriver
- Pick / Scribe
- Carb cleaner
- Gloves
- Overalls / Old Clothes
- Rags
- Old / New tootbrush
Time is subject to how stubborn the EGR is to get out and also how long you spend cleaning it up.
Before we start the information that follows is a narrative of how i went about cleaning my EGR and should you wish to use it its completley your own discretion and responsibilty.
Ok lets get to it start by disconnecting the negative terminal from the battery.
Then remove the plastic engine covers secured in place by 3 bolts place to one side.
TIP:- Place the bolts back on the threads and finger tight them reducing the risk of misplacing them.
OK now thats out the way locate the black tubing on the right hand side of the engine going into the inlet manifold.
slacken off the jubilee clip enough to remove the pipe off the butterfly body move it out the way as best you can to give you room to get at the EGR.
There she is that cylindrical looking thing with the white clip and wires coming out of it
to remove the wiring clip using the picture for orientation on the top right hand side of the connector you should see the securing clip lift that up andf then pull the connector off.
Ok get the ratchet ready and remove the 3 retaining bolts which secure the EGR once removed you
should be able to freely pull away the solenoid portion of the EGR if it dosn't come straight away give it a wiggle.
NOTE:- My picture shows my solenoid covered in oil as opposed to carbon build up this is due to the
fact i only had my EGR out about 4 weeks ago for cleaning and yes it was covered in carbon build up
this recent photo only taken this morning is due to the fact my turbo blew up on sunday.
Ok so using the carb cleaner spray the solenoid and leave to soak in whilst that is soaking in
turn to the other portion of the EGR still inset into the inlet manifold.
Using a Medium flatblade screwdriver gently manipulate it between the inlet manifold and the EGR
and start to gently jimmy the EGR out
As the Medium blade runs out of leverage i upped it toa larger blade and continued the EGR slowly progressing out of the inlet manifold i did use a hammer aswell to help it on its way by placing the screwdriver at angle and gentley tapping it out when the EGR got about half way out then got my mitts round it wriggled it it out the rest of the way.
NOTE:- It will be coated in soot and carbon build up and will be quite stubborn to get out mine certinly was when i did mine but that was 4 weeks ago when i pulled it out to clean it just keep slowly leavering it out and spray some Carb clean on it to try and help it on its way.
Also note in the picture the metal gasket i found it was re usable providing you did not damage it on removal.
Give it a good coating of Carb cleaner to soak in and start cleaning the solenoid portion.
Use the Pick and scribe to get rid off largq build ups of carbon and use a rags and a stiff bristled toothbrush to clean some of the lighter build ups.
when you are satisfied you have cleaned both parts of the EGR up spray the inlet manifold where the EGR slots into with the carb cleaner as that will be pretty caked up in there aswell using your toothbrush and rags.
Installation
All of the opposite of which you have just done
Place gasket over EGR and slot back into inlet manifold offer up solenoid portion and hold in place while you re-insert the 3 retaining bolts finger tight then get your ratchet to tighten them off 5 white knuckles did it for me but your call.
Reconnect wiring clip
Connect black tube to inlet manifold butterly housing
Re tighten jubilee clip
Refit plastic engine covers
Re-connect negative terminal on battery
Ensure you have all your tools and none are left in the engine area
Fire it up!
NOTE:- You may have to get car connected to a VAG com to remove the error code as a result of carrying out this job but the car still drives i didnt bother with mine.
It might be worth noting while you are working on the EGR to check out the inlet outlet pipes and airbox pipes going to the Turbo checking
the pipes and the surrounding areas for any oil that shouldnt be there as mine started getting the hessitation upon accelerating which led me to
clean the EGR out guess what 4 weeks later and one blown turbo i did start to get the tell tale signs just wasnt expecting that to happen so definatly check for signs of your turbo goin and listen out for signs it may be going.
Well i hope this helps
If you got any questions or feel i have missed something out drop me a message and ill update
Otherwise
Enjoy
:mechanic: Now where did i put that bolt???
