WARNING: This page is about a different car, the 2013 Volkswagen Jetta and 2012 Volkswagen Jetta. 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:
- If engine is to be cranked at starting speed without starting, for example during a compression pressure test, disconnect the connectors from the ignition coils and the 8 pin connector for the fuel injectors -3-.
- After performing the work, check and erase the Diagnostic Trouble Code (DTC) memory. Refer to "Guided Functions" in the vehicle diagnostic tester.
- 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.
- The battery must only be disconnected and connected with the ignition turned off, otherwise the Engine Control Module (ECM) can be damaged. Obtain the radio code for radios with a anti-theft code before disconnecting the battery.
- Follow required safety precautions after connecting the battery. Refer to Removal and Installation .
If special testing equipment is required during road test, note the following:
- Test and measuring instruments must be secured to the rear seat and operated by a second person from this location.
If test and measuring instruments are operated from the front passenger 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.
