Note
♦ The replacement compressor contains the full quantity of oil
intended for the refrigerant circuit. On A/C compressor re‐
placement, the quantity of oil in the A/C compressor is there‐
fore to be adjusted. Refer to
⇒ “5 Removal and Installation“, page 191 .
♦ The Audi A4 is equipped with different A/C compressors de‐
pending on engine and production period. The replacement
part for this A/C compressor has different oil capacities. Pay
close attention to the exact part number. Refer to ⇒ Heating,
Ventilation and Air Conditioning; Rep. Gr. 87 ; Description and
Operation (vehicle-specific repair manual) and to the Elec‐
tronic Parts Catalog.
♦ At start of production, the compressor types in the first line of
the table were supplied with a refrigerant oil quantity of 180
cm
3
. These compressors can be recognized from the index of
the part number (8E0 260 805 with one index or with double
index up to AH). In model year 2004 (as of approximately
01.04), a gradual change was made to other types of com‐
pressor with a refrigerant oil quantity of 120 cm
3
or 130 cm
3
.
These compressors can be recognized from the index of the
part number 8E0 260 805 (with a double index as of AJ) or 4F0
260 805 (and the index E for vehicles with 8-cylinder engine).
Refer to Electronic Parts Catalog (ETKA).
♦ The reason for the different oil capacities inside the A/C com‐
pressor is due to the design of the A/C compressor (with or
with an oil separator on the high pressure connection) or to the
design of the refrigerant circuit if the A/C compressors are
have the identical design. Pay attention to the different ca‐
pacities. Too much oil in the circuit leads to higher pressures
and reduces cooling performance of the system. Too little oil
may lead to lubrication problems in the compressor.
♦ A data plate may be attached to the A/C compressor by the
manufacturer, indicating the part number and refrigerant oil
quantity.
