R-320
Fuel filter 2008 R-320

Hello all!
I have an R-320 CDI with 60K miles on it.
The check engine light went on and its seems to be losing power.
I have never replaced the fuel filter so I believe its about time to
get this done. I have a replacement filter and no resources for a shop manual or Mercedes reference guide. Any suggestions?? This shouldnt be a complicated process so I was looking for some tips or assistance for procedures for filter replacement.
any help is greatly appreciated!
JB

Just go to StarTekInfo and sign up for a one day subscription, print off what you need and have fun. It is not that bad, but not simple.
I usually replace my fuel and air filters every 20K miles.
If the CEL is on, have the codes checked as something else could be an issue.
