    I've changed that hose on my car two weeks ago too.
    In my case though that wasn't the source of the hissing noise. It was the pipe between the turbo and EGR cooler.

    Yes, depends on the severity of the leak though, if its extreme then of course limp occurs, but minor it may just seem a little of key as such as its based the fuel levels on the air intake which it isn't receiving due to the leak, ideally it needs leak testing to be sure.

    Clean out exhaust, I used a cleaner from a agricultural company in Italy & cleaned it all out perfectly & no cat issues, smoking lasted seconds due to cleaning the whole lot out, never did it since.

    Hi guys

    same issue i have with some oil in the xhaust due to a blownnturbo...all is fixed now, though i'm experiencing a serious loss of power n boost (replaced boost pipenthat a leak) so am thinking maybe its a faulty EGR...am i thinking in the right direction?

    In what way is car down on power ? If its not picking up very well then it sounds like boost leak so u need to test the boost hoses with smoke machine also if its making a dump valve kind off noise its definately boost leak, oil will take a good 6mo ths to clear out or can be cleaned out with cleaner as mentioned above in a previous comment also you shpuld make sure all hoses are inserted into pipes properly as could be leaking from there aswel
