Egr cooler delete 335d e92 -2007
Discussion
Hey!
Im new to this website and this is my first post. Before I ask my question I just want to thank all of you guys. Without these forums there would be a lot harder to find information on problems on these cars. So thank you all for posting and sharing your experiences.
My question:
My EGR cooler is probably leaking. Im sometimes getting this cloud of white smoke when I drive. It will smoke like sh** and after a couple of minutes it is gone. It doesnt smoke so much now but there is this white liquid on the edge of the tailpipes and it feels a bit like oil but smells like burnt coolant. Some of you will probably say that it might be the head gasket. Well, I dont have any white residue on the oil cap. And the oil level is at half and barely moves when I check the dipstick from time to time.
A friend of mine who is a mechanic at bmw says that he is pretty sure that it is the egr cooler failing.
Anyway, when removing the cooler and the egr valve. Should I remove the whole assembly including what looks to be a thermostat? (Where my finger is laying on in the pic).
Also, should I just plug this line that goes to the egr valve? (Seen in pic 2)
Is it something I need to be aware of when doing this delete?
Should I just connect the coolant hoses to each other after removing the cooler?

Did they change the egr cooler on your 640d?
Seems like this part is prone to failure. I want to remove it completely instead of buying a new one every time it breaks.
Im running at 340hp with the dpf still fitted. Going for a dpf delete first then ill test to run without the egr for a while and see if it makes a difference.
Is there someone here who runs without EGR?
