The fuel system is under pressure! Before opening the system lay cleaning cloths around the connection point. Reduce pressure by carefully releasing the connection point.
Observe the following points to prevent injury to persons and/or damage to the injection and ignition system:
t  Do not touch or remove ignition leads with the engine running or at start speed.
t  Ignition must be switched off before disconnecting and re-connecting the cables of the fuel injection and the ignition system as well as of the test equipment.
t  If the engine must be operated at start speed without it starting, as for example, when checking the compression pressure, remove the fuse for the voltage supply of the injection valves and the ignition coils from the fuse holder → Current flow diagrams, Electrical fault finding and Fitting locations.
If test and measuring devices are required during test drives observe the following:
t  Always secure the test and measuring devices on the rear seat and have a second person operate them there.
t  If the test and measuring devices are operated from the passenger seat, the passenger could be injured by the release of the passenger airbag in the event of an accident.
