Hi all,
Bit of a basic question - sorry for my ignorance.
Where exactly do i spray EGR cleaner?
Is the blue circle my air filter housing? So i spray down the pipe circled red?
Citroen dispatch 1.6 Bluehdi XS 2018
Thank you

Re: Spray EGR Cleaner
This video is on a 1.6 HDi C4 but basically the same as your engine. It will show you how to go about it,
I used to be indecisive, now I'm not so sure!

I was almost on the the right track. So is that the turbo?

Re: Spray EGR Cleaner
I would be surprised if it worked, I have had various EGR valve's off different engines and sometimes struggle to get all the crap out by hand. I cant see how a spray wizin through would do much... Just my opinion
Thanx to all the admins & knowledgeable people that make this the best forum on the interweb. BUT COME BACK MARC , We miss you!

Re: Spray EGR Cleaner
My thoughts too, especially after having gone through the combustion process.
