Hi I have a w220 S320,2000 model... had it running really rough and found that the fuel filter had metal filings or partices in it which I also found stuck in 2 of the injectors...
Any idea as to what internally could of caused this?
Internal corrosion in the fuel line before and after the filter? Has the car been stored dry at any time? Maybe repair that required the lines to be removed and allowed to dry then reinstalled? I'm with you Derek, you can see filings--they ought not have got past the filter.
