Safety precautions
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 2nd person from this location.
If test equipment is operated from the front passenger's seat, the occupant could suffer injury in the event of an accident if the front passenger's airbag is triggered.
If the engine is to be turned at starter speed without starting:
–  Remove the fuse for the injector units and ignition coils the from the fuse holder. Fuse installation → Current flow diagrams, Electrical fault finding and Fitting locations
Consult fault memory; if necessary, repair any faults and then erase fault memory → Vehicle diagnosis, testing and information system VAS 5051“guided fault finding”
If the fault memory has been erased, you must generate the readiness code again.
