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 Parts Information.
| Vehicle model | 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 (8XF or 8XK model code) | 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 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 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 retroactivAPPROVED REFRIGERANT OILS AND CAPACITIES ely 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 APPROVED REFRIGERANT OILS AND CAPACITIES . 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 of refrigerant during production from 06/2014 through 11/2014. The refrigerant capacity was reduced from 500 g to 475 g 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 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 with a waterproof pen, if necessary (or replace the information label). Refer to Refrigerant Circuit (vehicle-specific repair information) and the Parts Information.
