2010 Audi A3 2.0T, 2.0 E, StandardSECTION Safety Precautions
WARNING: This page is about a different car, the 2007 Audi A3 and 2006 Audi A3. 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. Note the following:

CAUTION:

The fuel system is pressurized. Before loosening hose connections or opening the test connection (to measure fuel pressure), place a cloth around the connection. Then release pressure by carefully loosening the connection.

  • Always switch off ignition before disconnecting or connecting lines of the fuel injection and ignition system, including test leads.
  • During some of the tests, a Diagnostic Trouble Code (DTC) may be recognized and stored by the control module. At the end of all tests and repairs, the DTC memory should be checked and, if necessary, erased. After erasing the DTC memory, a readiness code must be generated for the engine control module.
  • Always switch ignition off before cleaning engine.
CAUTION:
  • The battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module (ECM) can otherwise be damaged.
  • Observe procedures for disconnecting battery.

Observe the following if test and measuring instruments are required during a test drive:

CAUTION:
  • Test and measuring equipment must always be secured to the rear seat and be operated from there by a second person.
  • If test and measuring instruments are operated from the front passenger's 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 deployed.
