    W211 E320cdi Eu3 or Eu4 ??

    Hi All, I have seen references of Eu3 and Eu4 for the E320cdi W211. How would I know which version I have? What are the differences? IceBoy

    EU4 to EU3

    Anyone know if its possible to convert an EU4 engine back to EU3? Car is a 2005 E320CDI (last of the straight 6 engines) I understand that the EU3 cars were 10% better on fuel economy
