Capacities For AUDI A1 (8X_) From My 2011
Features of the refrigerant system:
- Expansion Valve
- Receiver/Dryer
- "Denso", "Sanden" (or "Delphi/Mahle") A/C compressors with A/C Compressor Regulator Valve -N280-. Refer to Refrigerant Circuit (vehicle-specific repair information) and the appropriate Electronic Parts Information.
| Vehicle type | Production period | Capacity in grams | Differing features of this refrigerant circuit |
|---|---|---|---|
| Audi A1 (type key 8X1 or 8XA) | From 08/2010 through 06/2014 (running change) | 500 + / - 15 |
|
| Audi A1 (type key 8XF or 8XK) | From 06/2014 (running change) | 475 + / - 15 |
|
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 of production, A/C compressors manufactured by "Denso" type "6 SEU 14C" or "Sanden" type "7 PXE 16/14" were installed. Refer to the appropriate Electronic Parts Information and Refrigerant Circuit (vehicle-specific repair information).
Depending on the engine, A/C compressors from manufacturers "Sanden" type "11 PXC 14" or "Delphi/Mahle" type "6 CVC 140" may also be installed at a later time (introduction TBD, planned from 09/2012). Refer to the appropriate Electronic Parts Information and Refrigerant Circuit (vehicle-specific repair information).
From 11/2012 the refrigerant oil quantity for the "Denso" A/C compressor with the part number "5Q0 xxx xxx" was increased from 80 ccm to 110 ccm. The increased refrigerant oil capacity applies retroactively to all vehicles with this A/C compressor. For vehicles that were built through 11/2012 with this A/C compressor, check whether the refrigerant oil capacity was already topped up during a previous workshop visit. If not, fill the refrigerant circuit with an additional 30 ccm of refrigerant oil. Refer to CAPACITIES FOR AUDI A1 (8X_) FROM MY 2011 . Then note the refrigerant oil capacity with a waterproof marker on the sticker and fill the refrigerant circuit with the above-specified refrigerant quantity. Refer to Component Location Overview - A/C System (vehicle-specific repair information).
The evaporator, the expansion valve and the associated refrigerant lines were changed from 06/2014 (different lines, attachment points, etc.). These A/C systems were still filled with 500 g (17.6 oz) of refrigerant during production from 06/2014 through 11/2014. The refrigerant capacity was reduced from 500 g to 475 g (17.6 oz to 16.8 oz) from 11/2014. Reason: unfavorable ambient conditions (high ambient temperatures, dirty condenser, etc.) may cause excessive pressures in the refrigerant circuit when the capacity is 500 g (17.6 oz) on these vehicles. For vehicles that were built in this time period, check the capacity specification for the refrigerant on the information label and correct it to 475 g (16.8 oz) with a waterproof pen, if necessary (or replace the information label). Refer to Refrigerant Circuit (vehicle-specific repair information) and the appropriate Electronic Parts Information.
