Adaption of auxiliary/additional heater
Adaption of auxiliary/additional heater
The following adaption channels are provided for the auxiliary/additional heater
-
‒ For adaption of the fixed value of the undervoltage cut-off for coding "00XX2"
-
‒ For adaption (adjustment) of the CO2-content in the additional heater exhaust gas => Page 82-27
-
‒ Only for additional heaters with a control unit as of software version "D50"
-
‒ For adaption of the additional heater (only if when connecting contact "3" to earth of the additional heater 6-pin connector the heater does not operate and no other fault is present) => Page 01-97
Notes:
-
◆ Perform the "adaption" function in order to:
-
‒ Set the CO2 content in the exhaust gas (channel number "02") => Page 82-27
-
‒ To check, enter or alter the value for the manual undervoltage cut-off (cut-off occurs at a fixed voltage value, channel number "01") => Page 01-90
-
◆ The additional heater control unit -J162 allows only the adaption described here. No additional adaption options for the Audi A2 additional heater must be employed (e.g. for the version as auxiliary/additional heater).
=> Audi A8 auxiliary/additional heater
=> Audi A6 auxiliary heater
-
◆ On vehicles with additional heater, the voltage value can be modified within the specified limits. However, the voltage value entered should not be too high, so as not to jeopardise the heater function => Page 01-90
-
‒ The cut-off voltage of 9.5V that was set by the manufacturer can be varied within the specified limits.
-
‒ As the additional heateronly operates when the engine is running, the cut-off voltage is of secondary importance. No voltage higher than 10.0 Volts should be entered in order not to adversely affect additional heater operation.
