speed cannot be regulated):
- 1. Read measured value block (Function 08) =>Page

◆ If, when the ignition is switched on, no "Signal for ignition off time" has been detected by operating and
display unit -E87, the -E87 assumes a standing time of more than 4 hours and it is assumed that the engine
temperature is the same as the ambient temperature. It can happen when operating the heater that there
is a delay before the fresh air blower starts, even though the engine has reached operating temperature
(=>Page 31 Reading measured value block). The ambient temperature indicator -G106 in the dash panel
insert may display incorrect ambient temperature values.
