  Note
At present, remote control is available as an optional extra.
  Note
t  The auxiliary heating radio controlled receiver -R64- is installed on the left of the luggage compartment in the direction of travel behind the luggage compartment lining in the area behind the wheel housing → Chapter and → Radio, telephone, navigation; Rep. Gr.91
t  Only one activation/deactivation signal is transmitted by the auxiliary heater remote control hand transmitter. On vehicles with air conditioner, the auxiliary heater control unit -J364- determines the auxiliary heater start-up mode (auxiliary heating/auxiliary ventilation). The necessary information is obtained via the convenience data bus system from the operating and display unit, Climatronic control unit -J255- of the air conditioner and from the control unit in dash panel insert -J285-. On vehicles with no air conditioner, the function (auxiliary heating/auxiliary ventilation) is determined by the last setting in the control unit in dash panel insert -J285-.
  Note
t  On the Audi A4, the auxiliary heater ON/OFF signal is received by different aerials depending on vehicle model.
t  Saloon (and Coupe): By way of aerial in rear window
t  Avant: By way of aerial in rear left side window
t  Cabriolet: By way of aerial in boot lid → Radio, telephone, navigation; Rep. Gr.91, → Current flow diagrams, Electrical fault finding and Fitting locations and → Parts List
   
1 - Rear window aerial module
q   Designation in current flow diagram depends on vehicle equipment (e.g. aerial -R11- or telephone aerial -R65-)
q   On Saloon (and Coupe)
q   For vehicles with auxiliary heater remote control unit with additional outgoing circuit → Parts List
q   Fitting location → Radio, telephone, navigation; Rep. Gr.91
2 - Left aerial module -R108-
q   For Avant
q   For vehicles with auxiliary heater remote control unit with additional outgoing circuit (marked e.g. “TS”) → Parts List
q   Fitting location → Radio, telephone, navigation; Rep. Gr.91
3 - Aerial wire with aerial
q   Designation in current flow diagram is governed by vehicle equipment
q   For Cabriolet
q   Only installed on vehicles with auxiliary heater remote control unit → Parts List
q   Routed in boot lid → Radio, telephone, navigation; Rep. Gr.91
4 - Aerial wire from aerial module to auxiliary heating radio controlled receiver -R64-
q   On Saloon (and Coupe)
5 - Aerial wire from aerial module to auxiliary heating radio controlled receiver -R64-
q   For Avant
6 - Auxiliary heating radio controlled receiver -R64-
q   Transmits appropriate information to auxiliary heater control unit -J364- on reception of remote control signals (activation or deactivation of auxiliary heating/auxiliary ventilation)
q   Can be deactivated by auxiliary heater control unit -J364- (thus reducing no-load current input) → Chapter (Reading measured value block, display group “007”)
q   Checking signals from auxiliary heating radio controlled receiver -R64- → Chapter
  Note
t  The remote control hand transmitter is adapted in the auxiliary heating radio controlled receiver -R64- and not in the auxiliary heater control unit -J364- → Chapter (Adaption, adaption channel “004”).
t  The remote control hand transmitter signals are only relayed by the auxiliary heating radio controlled receiver -R64-. The auxiliary heater control unit -J364- then processes the signals → Chapter (Reading measured value block, display group “007”).
t  If the auxiliary heating radio controlled receiver -R64- is replaced, all hand transmitters have to be adapted → Chapter (the remote control hand transmitters are assigned in the auxiliary heating radio controlled receiver -R64- by way of the auxiliary heater control unit -J364-).
7 - 6-pin connector to auxiliary heating radio controlled receiver -R64-
q   Contact “1”
–  Output for ON and OFF signal to auxiliary heater control unit -J364- → Chapter
–  If the receiver is in power saving mode, no signal is supplied after/on pressing the remote control ON or OFF button → Chapter
q   Contacts “2”, “3” and “5”
–  Not used
q   Contact “4”
–  Earth
q   Contact “6”
–  Power supply (terminal “30”)
8 - Wiring to auxiliary heater control unit -J364-
q   Incorporated into vehicle wiring harness → Current flow diagrams, Electrical fault finding and Fitting locations
9 - 12-pin connector to auxiliary heater control unit -J364-
q   Contact “1”
–  From auxiliary heating radio controlled receiver -R64- to input for ON and OFF signal in auxiliary heater control unit -J364- → Chapter
q   If the receiver is in power saving mode, no signal is supplied after/on pressing the remote control ON or OFF button → Chapter
q   Procedure for electrical checks at connector → Chapter
q   Further pin assignment → Chapter and → Current flow diagrams, Electrical fault finding and Fitting locations
10 - Auxiliary heater control unit -J364-
q   Adaption of remote control hand transmitter in auxiliary heater control unit -J364- → Chapter (Adaption, adaption channel “004”)
q   If auxiliary heating/auxiliary ventilation is implemented by way of remote control, the operating and display unit, Climatronic control unit -J255- or the control unit in dash panel insert -J285- determines whether “auxiliary heating” or “auxiliary ventilation” mode is activated → Chapter
  Note
t  At present, a maximum of 4 remote control units can be adapted in the auxiliary heating radio controlled receiver -R64- (by way of the auxiliary heater control unit -J364-). Adaption of a fifth remote control unit causes the first matched remote control to be erased.
t  The remote control hand transmitter signals are only relayed by the auxiliary heating radio controlled receiver -R64-. The auxiliary heater control unit -J364- then processes the signals → Chapter (Reading measured value block, display group “007”).
t  The auxiliary heating radio controlled receiver -R64- can be deactivated by the auxiliary heater control unit -J364- (thus reducing no-load current input) → Chapter (Reading measured value block, display group “007”).
t  Checking signals from auxiliary heating radio controlled receiver -R64- → Chapter
t  If the auxiliary heater control unit -J364- is replaced, the function of at least one remote control hand transmitter must be checked (if function is not OK, all hand transmitters must be adapted to the auxiliary heater control unit -J364-) → Chapter (remote control assignment is performed in auxiliary heating radio controlled receiver -R64- by way of the auxiliary heater control unit -J364-).
