Note
♦
Replacement restrictors with different holes are available: yel‐
low colored 1.54 mm, red colored 1.42 mm.
♦
Depending on manufacturer, color of red restrictor may tend
more towards orange.
♦
To avoid altering the cooling output of the air conditioner, red
colored restrictors must only be installed.
♦
Different A/C compressors are installed depending on their
version. Refer to ⇒ Heating, Ventilation and Air Conditioning;
Rep. Gr. 87 ; Description and Operation and Electronic Parts
Catalog (ETKA).
♦
In contrast to vehicles with other engines, vehicles with the 10-
cylinder TFSI engine (Audi R S6) have a condenser with a
smaller interior volume installed. For this reason, the refriger‐
ant fill volume is slightly less in a 10-cylinder TFSI engine than
in other engines. Refer to Electronic Parts Catalog (ETKA).
