Capacities, AUDI A3 (8L_) 1997 Through My 2004 And AUDI TT (8N_), From My 1999
Features of the refrigerant system:
- Expansion Valve
- Fluid Reservoir
- A/C compressor manufactured by Sanden or Zexel / Valeo. Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Removal and Installation .
Capacities Audi A3 (8L_) 1997 up to 2004
| Vehicle model | Production period | Capacity in grams | Differing features of this refrigerant circuit |
|---|---|---|---|
| Audi A3 | As of 08.96 | 750 + 50 |
|
Exclusive use was made at the start of production of Sanden A/C compressors. As of model year 1999, use was also made of Zexel compressors. Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
If no condenser with a flat pipe width of 20 mm is available for Audi A3 as a replacement part, and a condenser with a flat pipe width of 16 mm is installed, only 650 + / - 20 g of refrigerant instead of 750 + 50 g may be filled in. In addition, capacity specification must be changed accordingly on sticker (to do so, please observe notes for Audi TT CAPACITIES, AUDI A3 (8L_) 1997 THROUGH MY 2004 AND AUDI TT (8N_), FROM MY 1999 ).
Beginning the production year 2006, the name of the Zexel A/C compressor was changed from Zexel to Valeo.
Capacities Audi TT (8N_) from MY 99
| Vehicle model | Production period | Capacity in grams | Differing features of this refrigerant circuit |
|---|---|---|---|
| Audi TT | As of 10.98 up to 10.03 (and as of 06.04 up to 08.04 CAPACITIES, AUDI A3 (8L_) 1997 THROUGH MY 2004 AND AUDI TT (8N_), FROM MY 1999 ) | 750 + 50 |
|
| As of 10.03 (except 06.04 up to 08.04 CAPACITIES, AUDI A3 (8L_) 1997 THROUGH MY 2004 AND AUDI TT (8N_), FROM MY 1999 ) | 650 + / - 20 |

Exclusive use was made at the start of production of Sanden A/C compressors. As of model year 1999, use was also made of Zexel compressors. Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
As of calendar year 2006, the Zexel / Valeo identification was changed to Valeo.
There was a change in production for Audi TT as of 10.03 (from vehicle identification number (VIN) 8N41015239) from condenser with part number "1J0 820 411 J" (flat pipe width of 20 mm) to condenser with part number " 8N0 820 411 A" (flat pipe width of 16 mm), refer to DETERMINING DIMENSIONS OF FLAT PIPES FROM CONDENSER . From 06.04 to 08.04, a certain number of vehicles not specified were equipped again with condensers having a flat pipe width of 20 mm.
Condensers with a flat pipe width of 16 mm require 120 g less of refrigerant than condensers with flat pipe width of 20 mm.
On the Audi TT, from 10.2003 (from VIN 8N41015239) through 06.04, a condenser with a 16 mm flat pipe width (part number " 8N0 820 411 A") was installed filled with 750 + 50 grams of refrigerant, and in addition to this, these vehicles have label with the incorrect filling quantity: 750 grams (or 700 grams in 06.04) instead of 650 grams, refer to STICKER FOR CAPACITY OF REFRIGERANT R134A . Due to overfilling of the system, the A/C compressor may be switched off under certain circumstances (for example high ambient temperatures) since the pressure in the refrigerant circuit is too high; in addition, drivers may complain about the engine performance (for example, rumbling and buzzing sounds, the engine is heavier loaded as the A/C compressor is working steadily against the excessive pressure). Solution: drain refrigerant circuit, then refill correct capacity and replace sticker with one indicating correct capacity specification, or cross out wrong capacity specification on sticker and note correct capacity, for example using a waterproof marker.
If condenser is replaced, observe flat pipe dimensions. If a condenser with another flat pipe dimension is installed, the sticker specifying the capacity for refrigerant R134a is also to be replaced, or the old capacity specification is to be removed and the new capacity is to be noted, for example, using a waterproof marker.
