Safety measures
To prevent injuries to persons and/or serious damage to the fuel injection and ignition system, the following must be noted:
t  Do not touch or remove the ignition cables with the engine running or idling.
t  The ignition must be switched off before connecting or disconnecting injection or ignition system wiring or tester cables.
If in the test drives it is necessary to use the tester units, take note of the following:
t  Testers and measuring instruments must always be secured to the rear seat and operated by a second 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.
If the engine is to be turned at starter speed without starting:
–  Remove the fuses in order to cut off the power supply to the injectors and the ignition coils. Fuse installation → Current flow diagrams, Electrical fault finding and Fitting locations
  Note
When removing the fuses, the power supply of the injectors and the ignition coils is interrupted.
Consult fault memory; if necessary, repair any faults and then erase fault memory → Vehicle diagnosis, testing and information system VAS 5051“guided fault finding”
After deleting the fault memory, the conformance code must be generated.
