Replacement restrictors with different holes are available: yellow 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 [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
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 refrigerant fill volume is slightly less in a 10-cylinder TFSI engine than in other engines.
