Releasing pressure in high-pressure area |
WARNING The injection system consists of a high-pressure section (maximum approx. 120 bar) and a low-pressure section (approx. 6 bar). |
Prior to opening the high-pressure area, e.g. when removing the high-pressure pump, fuel rail, injectors, a fuel line, or the fuel pressure sender -G247-, the fuel pressure in the high-pressure area must be reduced to a residual pressure of approx. 6 bar. The appropriate procedure is described as follows. |
|
WARNING The fuel line is under pressure. |
Risk of injury to eyes and skin from fuel. |
Wear eye protection and protective clothing to avoid eye injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully opening the connection point. |
|
–
| Wrap a clean cloth around the connection and carefully open to release residual pressure of approx. 6 bar. Catch the escaping fuel. |
–
| After completing work, read event memory of engine control unit, erase all entries that may have been created by pulling off connector. |
