To prevent injuries to persons and/or damage to the fuel injection and ignition system, the following must be noted:

CAUTION: When doing any repair work, especially in the engine well, due to the cramped conditions, pay attention to the following:

Route all sorts of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.

Ensure sufficient clearance to all moving or hot components.

Do not touch or disconnect ignition wiring when the engine is running or being turned at starter speed.
The ignition must be switched off before connecting or disconnecting injection or ignition system wiring or tester cables.
If the engine is to be turned at starter speed, without starting, e.g. when checking compressions, pull connector off output stage:
