Additional procedures tested and approved by Audi as well as corresponding information about them. Refer to ODORS IN VEHICLES WITH A/C SYSTEM
A/C unit may be contaminated by other substances
- Only use a suction feed spray gun and a spray lance that were not already used with other fluids.
The vacuum cleaner is only necessary if there is dirt in the plenum chamber or in the A/C intake shroud, or if dirt has gotten into the evaporator housing through the dust and pollen filter.
The :VAS6288 is only necessary if dirt has gotten into the evaporator housing through the dust and pollen filter.
It is recommended to have several short and long spray lances, since they are used either in their straight form, or must be bent to different degrees for various vehicles (or they are already bent). Repeatedly changing the form of the spray lance will damage it and is therefore not advisable.
Recommended bend radius of the :VAG1538/5 -A- for this vehicle.
The guide washer -B- is attached opposite of the spray lance holes -C-. This also allows the spray direction to be recognized when the spray lance is inserted.
The :VAG1538/5 -A- with this bend radius is also suitable for the following vehicles, for example: Audi A1 from MY 2011, Audi A4 from MY 2008, Audi A5 from MY 2008, Audi Q5 from MY 2009, Audi A6 from MY 2011, Audi A7 from MY 2011 and Audi A8 from MY 2010.
