Battery, Disconnecting And Connecting: Notes

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:

Risk of accident:

  • When working on pyrotechnic components (such as airbags and belt tensioners), the battery must be disconnected with the ignition switched on.

TDI (SCR) vehicles

  • After the ignition is switched off, the reducing agent goes from the metering line to the Reducing Agent Injector -N474- and back into the reducing agent active chamber.
  • Wait until all the reducing agent has been returned before working in this area. This could take up to 10 minutes after switching off the ignition.
  • Only after this is complete can the battery be disconnected. Again, this could take up to 10 minutes after switching off the ignition.
