A4 Mk3
|
| Capacity for Audi A3 (8L_) 1997 to 2004 |
| Vehicle model | Production period | Capacity in grammes | Differing characteristics of this refrigerant circuit | ||
| Audi A3 | From 08.96 onwards | 750 + 50 |
|
Note| t | Exclusive use was made at the start of production of „Sanden“ air conditioner compressors. With effect from Model Year 1999, use has also been made of „Zexel / Valeo“ air conditioner compressors → Heating, air conditioning; Rep. gr.87 and → Electronic parts catalogue. |
| t | If no replacement condenser with a flat tube width = 20 mm is available for an Audi A3 and a condenser with a flat tube width = 16 mm is fitted, only 650 + / - 20 g of refrigerant are to be added instead of 750 + 50 g. In addition the capacity given on the label must be altered accordingly (heed notes on Audi TT → Anchor). |
| t | The logo of the compressor manufacturer „Zexel“ attached to the air conditioner compressor was modified from „Zexel“ to „Valeo“ from year of production 2006 onwards (change in manufacturer's name). |
| Capacity for Audi TT (8N_) 1999 ► |
| Vehicle model | Production period | Capacity in grammes | Differing characteristics of this refrigerant circuit | ||
| Audi TT | From 10.98 to 10.03 (and from 06.04 to 08.04 → Anchor) | 750 + 50 |
| ||
| From 10.03 onwards (except 06.04 to 08.04 → Anchor) | 650 + / - 20 |

Note| t | Exclusive use was made at the start of production of „Sanden“ air conditioner compressors. With effect from Model Year 1999, use has also been made of „Zexel / Valeo“ air conditioner compressors → Heating, air conditioning; Rep. gr.87 and → Electronic parts catalogue. |
| t | The air conditioner compressor designation „Zexel / Valeo“ was changed as of 2006 to „Valeo“. |
| t | With effect from 10.03 (as of vehicle identification number 8N41015239), production of the Audi TT was switched from the condenser with part no. „1J0 820 411 J“ (with a flat tube width of 20 mm) to the condenser with part no. „8N0 820 411 A“ (with a flat tube width of 16 mm) → Anchor. In the period between 06.04 and 08.04, a certain number of vehicles was again fitted with condensers with a flat tube width of 20 mm. |
| t | Condensers with a flat tube width = 16 mm must be filled with approx. 120 g less refrigerant than condensers with a flat tube width = 20 mm → Electronic parts catalogue. |
| t | In the period between 10.03 (vehicles as of vehicle identification number 8N41015239) and 06.04, the Audi TT was fitted at the factory with a condenser with a flat tube width of 16 mm (part no. „8N0 820 411 A“) and the refrigerant circuit filled with 750 + 50 grammes of refrigerant. These vehicles were also provided with a sticker showing the incorrect capacity - namely 750 grammes (or 700 grammes in 06.04) instead of 650 grammes → Anchor. Under certain ambient conditions (e.g. high ambient temperatures), over-filling of the systems may result in the air conditioner compressor being shut off on account of excess pressure in the refrigerant circuit. Complaints may also be received about engine performance (e.g. humming and drumming; the engine is subjected to greater load as the air conditioner compressor constantly has to cope with excessively high pressure). Remedy: Discharge the refrigerant circuit, then re-charge with the correct quantity and replace the label with a label indicating the correct capacity or delete the old capacity indicated on the label and enter the new capacity in waterproof ink for example. |
| t | Pay attention to flat tube dimensions if condenser is renewed. If a condenser with different flat tube dimensions is to be fitted, also replace the label indicating the refrigerant R134a capacity or delete the old capacity and enter the new capacity in waterproof ink for example → Electronic parts catalogue. |
