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
or yellow colored restrictors must only be installed. Yellow col‐
ored restrictors were installed in model year 2001. Red colored
restrictors were installed as of model year 2002. The restrictor
modification (a red colored restrictor may also be installed in
vehicles of model year 2001 instead of a yellow colored re‐
strictor) does not alter the capacity for these vehicles.
♦ Depending on time period of production and depending on
engine, different A/C compressors are installed (these A/C
compressors do not have an A/C clutch)
♦ At the start production, Denso A/C compressors 6 SEU 12 and
7 SEU 16 were installed. As of model year 2004, there was a
running change to other Denso compressor types (6 SEU 14
and 7 SEU 17). Refer to ⇒ Heating, Ventilation and Air Con‐
ditioning; Rep. Gr. 87 ; Description and Operation (vehicle-
specific repair manual) and Electronic Parts Catalog (ETKA).
♦ The Audi RS 4 has an condenser with a smaller internal vol‐
ume, therefore the capacity for this model is less than for other
models. Refer to the Electronic Parts Catalog.
