| Encoding the operating and display unit for air conditioner/Climatronic -E87- |

Note | t
| The operating and display unit for air conditioner/Climatronic -E87- is encoded in the Audi A2 by means of the control unit in the dash panel insert -J285- and the convenience system central control unit -J393-. The data is transmitted to the operating and display unit for air conditioner/Climatronic -E87- via the “data bus system”. The encoding which is currently valid is displayed in the measured value block → Chapter. and → Electrical System; Repair group 01 |
| t
| There is no facility at present for direct code input into the operating and display unit for air conditioner/Climatronic -E87- (however, this feature may be introduced for optional extras at a later date). |
| t
| If the control unit in the dash panel insert -J285- was encoded for the “Japan” country variant, the air conditioner remains in recirculated-air mode after switching the ignition off and on again, if recirculated-air mode had been selected before the ignition was switched off. |
