WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.

The following safety precautions have to be observed for these cooling aids (additional laws may apply for different countries)

Empty (evacuate) refrigerant circuit first if the refrigerant circuit has to be opened during service. See A/C REFRIGERANT SYSTEM (R-134A), EVACUATING AND RECHARGING . The refrigerant must not come in contact with your skin. If refrigerant should escape although all safety precautions were observed, do not inhale refrigerant/air mixture.

The subassemblies and lines of the air conditioner are filled with

1.1.1.2 Tetrafluoroethane (CF 3  -CH 2  F or CH 2  F-CF 3  ) 

This refrigerant is currently known as R134a, H-FKW 134a, SUVA 134a and KLEA 134a (different names may apply to different countries.

  • Refrigerant R-134a replaces the refrigerant R-12 which is reported to have harmful effects on the earth's ozone layer.
  • R-134a and R-12 systems are similar in design but there are very important differences in the refrigerants, lubricating oils, service equipment and A/C system components.

Reason: 

If refrigerant R134a is released into the environment, it enhances the green house effect.

NOTE:
  • Compared to R12, R134a has a substantially lower green house effect.
  • Because R-134a does not contain chlorine atoms, the major catalyst in ozone depletion, R-134-a has no ozone depletion potential. The ozone depletion in the upper atmosphere is only initiated by splitting carbon-chlorine bonds (e.g. properties of R12)

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
