Safety Precautions
WARNING: This page is about a different car, the 2012 Volkswagen Touareg and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Very hot fuel can burn your skin.
- In extreme cases, the fuel lines and the fuel itself in vehicles with a common rail engine can be as hot as 100 °C (212 °F) after the engine has been turned off. Let the fuel cool down before opening any line connections otherwise there is a danger of scalding.
- Wear safety gloves.
- Wear protective eyewear.
There is a risk of injury because the fuel is under pressure.
- If the battery is not going to be disconnected, then for safety reasons, remove the fuse from the Fuel Pump Control Module -J538- before opening the fuel system. Otherwise the door contact switch on the driver door will activate the fuel pump.
- Place clean rags around the connection before opening the system. Then release pressure by carefully loosening the connection.
- Wear safety gloves.
- Wear protective eyewear.
If special testing equipment is required during road test, Note The Following:
- Test and measuring instruments must be secured to rear seat and operated by a second person from this 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.
WARNING:
Secure the scan tool on the rear seat and have a second technician operate it from there.
To reduce the risk of personal injury and/or damage to the fuel injection and glow plug system, always observe the following:
CAUTION:
- Always follow the instructions when disconnecting the battery. Refer to BATTERY .
- Only disconnect and reconnect wires for glow plugs and fuel injection system, including test leads, when ignition is turned off.
- If the engine will run at starter speed without starting, disconnect the connector from the Fuel Pressure Regulator Valve -N276- .
- Obtain the code for anti-theft radios before disconnect the battery.
- Always switch the ignition off before disconnecting or connecting the battery. Failing to do so could damage the diesel direct injection system control module.
