Safety precautions when working on the injection and glow plug system
To prevent injuries to persons and/or damage to the fuel injection and glow plug system, note the following:
t  The operation of piezo systems and control units requires very high voltages; certain components can cause injury if touched directly.
t  Persons wearing a cardiac pacemaker must at all times maintain a safe distance from high-voltage components such as piezo systems and gas-discharge headlights.
t  Always switch off the ignition before connecting or disconnecting tester cables or electrical wiring for the injection or glow plug system.
t  Do not open any fuel line connections while the engine is running.
t  Always switch off ignition before washing engine.
t  Certain tests may lead to entries being stored in the event memory of the engine control unit. Therefore, interrogate and, if necessary, erase the event memory after all repairs and tests → Vehicle diagnostic tester.
