Clean Working Conditions

When working on the exhaust gas recirculation (EGR) system, pay careful attention to the following "7 rules" of cleanliness:
- Thoroughly clean all connections and surrounding area before disconnecting.
- Place parts that have been removed on a clean surface and cover them. Use lint-free cloths.
- Carefully cover over opened components or seal, if repairs are not performed immediately.
- Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored loose (e.g. in tool boxes etc.).
- Transport and protective packaging and sealing caps are to be removed only immediately prior to installation.
- During repairs, clean oil from connections and hose ends.
- When system is open: Avoid working with compressed air if possible. Do not move vehicle unless absolutely necessary.
