Anybody got a "how to" for checking/cleaning the EGR on a 2002 c220 cdi?
There appears to be a lot of threads where the answer is "clean the EGR". I cannot find one that gives me enough confidence to tackle the job.
I believe that I may need to clean mine, power is down, fuel consumption has increased, and I emit clouds of black smoke at over 3000 rpm.
As I have recently had all of my injectors refurbished and a new MAF, it points to the EGR (unless one of my refurbished injectors has gone faulty). As I have now done over 220K miles, it is likely to be very dirty, maybe sticking.
As I have never had to deal with an EGR before, I would appreciate if someone could tell me how to find it, what it looks like, and what I need to remove to get at it. Any suggestions about what to use to clean it? How fragile is it?
Pictures would be great.
Thanks
