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.

For m.y. 1997, the illumination of the display 
field and the operating button is via light 
emitting diode (LED), and can not be replaced. 
     Always refer to parts information for correct 
control head versions. 
     Control heads with part number 8D0 820 043 
should only be installed in vehicles through m.y. 
1996. 
     Control heads with part number 8L0 820 043 
should only be installed in vehicles beginning 
m.y. 1997. 
     A/C control head -E87- with Part No. 8D0 820

M.y. 1997 vehicles can only have A/C control head -E87- with the Part 
No. 8L0 820 043 up to and including Part No. index letter "C." For m.y. 1998 the harness connector to A/C control head -E87- has

Notes:  
     
If both display fields of A/C control head -E87- 
(Part No. 8L0 820 043 beginning with Part No. 
index letter "D") are not illuminated when the 
ignition is switched on, check the voltage supply 
from terminal 58d (dimmer) to A/C control head 
-E87-  page 01

 (Electrical test). 
     
If the buttons for A/C control head -E87- (Part 
No. 8L0 820 043 beginning at Part No. index 
letter "D") do not light up when the light is 
switched on, check the voltage supply from 
terminal 58s (illumination) to A/C control head -

If an A/C control head -E87- with the Part No. 
8L0 820 043 beginning with Part No. index 
letter "D"is installed in a 1997 m.y. vehicle, the 
brightness in the switch cannot be changed

-136
 ). 
    
Install strap -A- (on bracket for motor) first into mounting -B- (on 
heater/air conditioning assembly). After installing, always check DTC memory   page 01

Wiring harness must be installed so that it does not come in contact 
with moving components (e.g. motor linkage). If the crank on the motor is positioned so that the lever can not be 
hooked in or the motor can not be installed, connect motor to the 
wiring harness, switch on ignition and place lever in appropriate 
position by activating the button for air distribution on A/C control head 
-E87-.
