If 22 C (71 F) is always displayed after
switching on the ignition regardless of the last
setting, check voltage supply to E87 (terminal
30) using wiring diagram.
E87 readout can be switched over from C to
F and vice versa by pressing the "temperature
+" and "recirculating air" buttons
simultaneously.
If E87 remains in operation after switching off
the ignition, test cable connection to E87
connector -D- contact -1- for short circuit to
positive (connection for auxiliary heater
operation) using wiring diagram.
