so I followed this instruction, (lucky for me someone already removed heat shield so I didn't have to eff with that.
And you do not have to remove the EGR cooler (radiator) just need to remove 4 bolts and that is it. Be carefull not to lose wrench behind the engine or a nut
When it comes to cleaning, I just spray it heavily with brake cleaner until its nice and clean, (just avoid electric part you can be careful its not that big of a deal if some of it sprays on it) Not sure how effective it is, once It was decently dirty and car ran great after clean, next time I had a judder and was able to bet it was dirty but it really wasnt that bad. Then I plugged it on diagnostics and saw that it has an intermittent error for EGR, I literally know when it pops up but it hasn't been bugging me for a while. Good thing that you have to so you can swap from car to car
Hi Neecola, I have been reading your messages on EGR blanking and I agree with you and the car does not run properly with it blanked. I have tested this also with it blanked and it run ok but sometimes it can run rough and have low flat spots at certain revs. The MPG is slightly lower also. I have now removed the blanking plate and it runs so much better and smoother. I have 2 cars 407 sw and my older one is suffering with EGR problem so I want to know how you remove and clean it because I would like to do the same. My other 407 egr is working perfectly at the moment. Thank you very much
Hey awesome that you messaged me, thanks for the reply, well with mine it foams when its cold, and on low speed there is juddering when turning the wheels so I will probably try your fix since it is pain in the ass to pour extra half of the liter every winter
Hey mate, I know that it is low chance that you will read it but I want to try, its about https://www.peugeotforums.com/forums/101440-post24.html
So you connected the return hose to the new 1/4 inch hose you placed in? Correct? So you drill out out place where return hose were fit originally? Correct?
I got tired of people telling me I need to replace pump or to service it as nobody can tell me WHY but you offered an explanation that makes sense. I am willing to try it but not to break something so I am checking that this I understood you
Hope you see this
Oh hello neecola. I just logged into the forums and saw your question. Well thing is, that externally everything stays like it is from factory. I just made return hole larger in pump body/reservoir and installed extra tube there. You can start by just making the hole bigger and see if it helps. What is wrong with your steering pump anyway - is the fluid foaming?
