Safety Precautions
WARNING: This page is about a different car, the 2009 Volkswagen GTI and 2008 Volkswagen GTI. However, it is still accessible from the selected car via links, so may be relevant.
To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:
- Do not touch or disconnect the ignition coils with power output stages when the engine is running or turning at starting speed.
- Only disconnect and reconnect wires for the injection and ignition system, including test leads, when the ignition is turned off.
- If the engine is to be cranked at starting speed without starting, disconnect the connectors from the ignition coils and fuel injectors. After performing work, check and erase the Diagnostic Trouble Code (DTC) memory.
- Cleaning the engine should only be performed with the ignition turned off.
- The battery must only be disconnected and connected with the ignition is turned off, since the Engine Control Module (ECM) can otherwise be damaged.
If special testing equipment is required during a road test, note the following:
- Testing and measuring instruments must be secured on the rear seat and operated by a second person from that location.
If the vehicle is involved in a collision while testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.
