  Caution
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  Ensure that there is sufficient clearance to all moving or hot components.
To prevent injuries to persons and/or damage to the injection and ignition system, the following must be observed:
t  Switch off ignition before connecting or disconnecting injection and ignition system wiring as well as test instrument cables.
t  If the engine is to be turned at starter speed without starting:
   
–  Pull off all 4-pin connectors -arrows- from ignition coils.

–  Pull fuse no. 28 and 32 out of fuse holder.
  Note
Removing the fuses interrupts the voltage supply to the injectors and the fuel pump.
Observe following if test and measuring instruments are required during a test drive:
t  Test and measuring instruments must be secured to rear seat and operated by a second person from this location.
If test and measuring instruments are operated from front passenger seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.
