Refrigerant R134a Servicing - Edition 01.2011
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
Different A/C compressors are installed depending on pro‐
♦
duction period and engine.
At start of production, exclusive use was made of A/C com‐
♦
pressors 7 SEU 16 from Denso (for example, A/C compressor
with part no. 1K0 820 803 up to index D). In model year 2004
(as of approximately 10.03), a gradual change was made to a
different type of Denso A/C compressor (7 SEU 17 for exam‐
ple, A/C compressor with part number 1K0 820 803 as of index
E).
Beginning the production year 2006, the name of the Zexel A/
♦
C compressor was changed from Zexel to Valeo.
As of MY 2008, and depending on the engine, A/C compres‐
♦
sors made by Denso (6 SEU 14) and Delphi are being instal‐
led. Refer to the Electronic Parts Catalog and ⇒ Heating and
Air Conditioning; Rep. Gr. 87 ; Description and Operation .
These A/C compressors are available as replacement parts
♦
with different oil fill capacities, therefore note capacity on the
A/C compressor and the exact part number. Refer to the ⇒
Heating and Air Conditioning; Rep. Gr. 87 ; Removal and In‐
stallation and Electronic Parts Catalog.
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.
