WARNING!
When doing any repair work, especially in the engine compartment, 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 pull off ignition wiring when engine is running or turning at starter speed.
- The ignition must be switched off when disconnecting or connecting injection and ignition system wiring as well as test instrument cables.
- If the engine is to be turned at starter speed, without starting:







- Disconnect 6-pin connector off power output stage for ignition coils -arrow-.







- Remove fuse 32


NOTE: Removing fuse 32 interrupts the voltage supply to the injectors.


Observe following if test and measuring instruments are required during a test drive:
- Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location.

If test and measuring instruments are operated from front passenger's 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.
