Hi all, posting my pics following an EGR overhaul on my 2006 plate Scenic Grand 1.9 DCi. Engine is the F9Q version 80 E I think?
**Please note I changed my glow plugs at the same time if this does not apply ignore some of the sections!**
Ok first things 1st before you even start make sure you have an ex torx socket if like my engine you have the external torx bolts on the EGR pipe, mine was an 8mm socket
The rest just involves your run of the mill spanner and socket set and a torx screwdriver set
I bought some carb cleaner in advance, take your pick there are many to choose from, i also had a little stiff brush (old toothbrush will do)
Disconnect battery
Remove the cover off car to expose the shroud covering your glow plugs etc (sorry if some of the terminology is not exact, i'm not a mechanic:d)
There are several things that I removed in order to make life easier and get better access, choose whatever suits you best.
Undo the plastic screws covering windscreen shroud
10mm plastc nuts and 2 x torx screws at each end
Remove the rubber strip and rubber stops at each end.
Next remove the 1st piece of plastic shroud covering the windscreen wipers
Ok now pop of the three covers that hide the nuts securing the windcreen wipers, unscrew and remove, i didn't need a puller for mine they came off with ease.
I also removed the plastic covers in the corners
Remove wipers
Next its time to start removing the firewall panels
note the position of the bolts, it comes aprt in two sections, smaller panel to the right (for access to air filer box) and larger panel to the left, jiggle it a bit to get it out or remove the pipes to manifold and remove shroud over glow plugs whichever makes life easier
Undo the two nuts holding this part of the manifold
unclip the the pipe next to it
Once done you can fold the flexible pipe out of the way to remove the shroud over the glow plugs
Allowing access if you need to examine or change them
Next I removed the two ex torx bolts from the EGR pipe
Then remove the 3 bolts holding the EGR in place, last one at rear near bottom, I used a 13mm spanner
Once I did this I could wiggle the EGR out
This is what I saw
Pretty carbed up!
So I cleaned it
OK not content with that, I wanted to check the motor, I took the cover off (more torx screws) checked the cogs (no broken teeth) and then placed two spade connectors on the motor to test it on the battery, it span fine so I knew it worked:d
I moved the cog by hand and the valve moved freely
Put it all back together and reassembled.
The valves cost in excess of £200.00 so for me it was worth checking and cleaning. Mine had stuck, it was burning loads of fuel, now closed:d
Hope this helps someone along the way
