It is time to clean the EGR. My idea is to try out Wynn's Diesel EGR Cleaner. I am new to diesel engines though, so I figured it is best to get some answer from the forum. Where is the best place to use the spray? I was assuming that I should remove the hose at that the red arrow is pointing to? Any suggestions?
You could do it there however you would be missing loads of the inlet track. I would remove the air intake after the air flow meter & spray it in there, that way it will also clean the turbo & intercooler. Its the pipe just to the right of the brake fluid reservoir in the pic.
It would work if you sprayed it up there but you wouldn't get the full advantage of cleaning the whole inlet track. Also you need to rev the engine a bit when you use EGR3 spray, you may find the engine would go into limp mode if you disconnected the pipe straight at the inlet manifold.
Remember also when you use the pipe i suggested it will most likely log a mass air flow fault, remember to go in & clear the fault codes afterwards.

I'd agree with this. It's what I did when using the spray, you will need someone in the car keeping constant revs let's say 2k and warn them not to panic when the revs start rocketing it's the spray doing it.
